Geospatial and Temporal Patterns of Natural and Man-Made (Technological) Disasters (1900–2024): Insights from Different Socio-Economic and Demographic Perspectives

Abstract

This pioneering study explores the geospatial and temporal patterns of natural and human-induced disasters from 1900 to 2024, providing essential insights into their global distribution and impacts. Significant trends and disparities in disaster occurrences and their widespread consequences are revealed through the utilization of the comprehensive international EM-DAT database. The results showed a dramatic escalation in both natural and man-made (technological) disasters over the decades, with notable surges in the 1991–2000 and 2001–2010 periods. A total of 25,836 disasters were recorded worldwide, of which 69.41% were natural disasters (16,567) and 30.59% were man-made (technological) disasters (9269). The most significant increase in natural disasters occurred from 1961–1970, while man-made (technological) disasters surged substantially from 1981–1990. Seasonal trends reveal that floods peak in January and July, while storms are most frequent in June and October. Droughts and floods are the most devastating in terms of human lives, while storms and earthquakes cause the highest economic losses. The most substantial economic losses were reported during the 2001–2010 period, driven by catastrophic natural disasters in Asia and North America. Also, Asia was highlighted by our research as the most disaster-prone continent, accounting for 41.75% of global events, with 61.89% of these events being natural disasters. Oceania, despite experiencing fewer total disasters, shows a remarkable 91.51% of these as natural disasters. Africa is notable for its high incidence of man-made (technological) disasters, which constitute 43.79% of the continent’s disaster events. Europe, representing 11.96% of total disasters, exhibits a balanced distribution but tends towards natural disasters at 64.54%. Examining specific countries, China, India, and the United States emerged as the countries most frequently affected by both types of disasters. The impact of these disasters has been immense, with economic losses reaching their highest during the decade of 2010–2020, largely due to natural disasters. The human toll has been equally significant, with Asia recording the most fatalities and Africa the most injuries. Pearson’s correlation analysis identified statistically significant links between socioeconomic factors and the effects of disasters. It shows that nations with higher GDP per capita and better governance quality tend to experience fewer disasters and less severe negative consequences. These insights highlight the urgent need for tailored disaster risk management strategies that address the distinct challenges and impacts in various regions. By understanding historical disaster patterns, policymakers and stakeholders can better anticipate and manage future risks, ultimately safeguarding lives and economies.

1. Introduction

In our increasingly interconnected world, grasping disasters’ geospatial and temporal patterns has become vital for effective disaster management and resilience planning [1]. Disasters, whether natural or human-induced, can have profound impacts on communities, economies, and the environment [2,3]. Environmental hazards, particularly air pollution, are of critical importance due to their role in increasing the susceptibility of populations to both natural and technological disasters. Specifically, air pollution poses direct threats to health and also compounds the effects of other environmental stressors, thereby elevating the overall risks faced by communities [4].

Advances in big data analytics, alongside the integration of various data sources, have greatly enhanced our ability to track and assess these risks [5]. For instance, the utilization of big data has enabled the merging of a wide range of environmental information, resulting in more refined risk evaluations and the formulation of more precise mitigation strategies [6]. These advancements are becoming indispensable for addressing the complex challenges posed by the convergence of air pollution with other disaster-related risks. The risk of a disaster occurring is always a combination of vulnerability and exposure due to inadequate preparation or coping capacity [7]. This underscores the necessity of delving into the complex dynamics that influence their occurrence and distribution.

Environmental events like earthquakes, floods, hurricanes, and wildfires are driven by natural and climatic forces [8,9,10,11,12,13,14,15]. The patterns of these disasters, including their frequency, intensity, and locations, have evolved over time due to shifts in climate, land usage, and population growth [16,17,18,19,20,21]. Also, trends can be uncovered and high-risk areas identified through the analysis of past data, thus improving the ability to forecast and respond to future events [22]. In contrast, man-made (technological) disasters arise from human activities such as industrial mishaps, nuclear accidents, and oil spills. These incidents often occur due to equipment failures, human and organizational mistakes [23], or weak regulatory measures. Failures can occur during the design, construction, operation or maintenance phases [24,25]. Insights into industrial operations and regulatory practices can be gained by examining when and where these disasters happen, leading to improved safety protocols and emergency response strategies [26].

Recent research has shed light on significant advancements and methodologies for understanding the geospatial and temporal patterns of natural disasters [27,28,29]. Han et al. [30], for instance, use textual records to uncover the spatial–temporal patterns of natural disasters in China. Their findings highlight critical intervals and interactions between events, offering valuable guidance for disaster prevention efforts [30]. Ghosh [31] explores the integration of various geospatial technologies and data sources in disaster management. Also, he emphasizes how AI and big data can enhance emergency responses and decision-making processes. On the other hand, Wang [32] delves into the historical patterns of marine disasters in China, providing a multiscalar analysis of their temporal changes and spatial evolution. This research helps in understanding long-term trends and impacts (Wang, 2020). Additionally, Wei et al. [33] conduct a comprehensive study on the spatial–temporal evolution and prediction of flood disasters in China over the past 500 years, highlighting critical trends and future risks. Together, these studies deepen our understanding of disaster patterns and offer valuable insights for effective disaster management and mitigation strategies.

The wealth of existing research on this subject provides crucial insights into the factors shaping these disaster patterns [32,33,34,35,36,37,38,39,40,41,42]. Geospatial analyses have revealed that some areas are particularly at risk for specific types of disasters. Factors such as the terrain, local climate, and how densely populated an area is significantly influence where these disasters occur [13]. Moreover, by studying temporal patterns, researchers can identify seasonal or cyclical trends and assess how climate change might be altering the frequency and severity of these events [43,44]. In addition, one study highlights the significant toll natural disasters can take on mental health, stressing the importance of comprehensive post-disaster intervention strategies to tackle the behavioral and psychological symptoms that follow such events [45].

Regarding this, the aim of this study is to provide a scientific description and comprehensive understanding of the patterns and impacts of natural and man-made (technological) disasters over more than a century. By analyzing the geospatial and temporal distribution of these events, this study aims to offer valuable insights that can inform future disaster risk management strategies, enhance preparedness, and ultimately contribute to reducing disaster-related losses. This research highlights the urgent need for tailored disaster risk management strategies that address the distinct challenges and impacts in various regions, thereby promoting resilience and sustainable development. A comprehensive understanding of the specific challenges and impacts encountered by different regions is crucial for developing strategies that not only bolster the resilience of these communities to future disasters but also align with broader sustainable development objectives. For example, addressing vulnerabilities related to infrastructure and socio-economic factors can foster more resilient systems that contribute to long-term sustainability and effectively reduce the risk of future disasters.

Literature Review Geospatial and Temporal Patterns of Disasters

Understanding and managing the effects of natural and man-made (technological) disasters have been significantly improved through geospatial analysis [46,47]. Analyzing historical data through geospatial techniques unveils patterns in the frequency and distribution of natural disasters worldwide [48]. This type of analysis is essential for grasping the temporal and spatial behaviors of these events, which in turn is critical for making accurate future predictions and improving disaster preparedness efforts [17,49]. Utilizing tools like remote sensing and GIS, researchers can now map out affected areas, predict potential damage, and evaluate the aftermath of these events [50]. This technological approach greatly supports efforts in disaster preparedness, effective response, and efficient recovery [17]. Geospatial technologies, including GIS and remote sensing, have proven to be highly effective tools for mapping and predicting natural disasters such as earthquakes, landslides, floods, and cyclones [47]. By utilizing these advanced technologies, researchers can accurately identify areas that are at high risk for such events.

Moreover, these tools play a vital role in developing early warning systems that can help mitigate the impact of disasters by providing timely alerts and enabling better preparedness [35,36,41,51]. Remote sensing and geospatial analyses play a crucial role in evaluating damage and monitoring recovery efforts following disasters [42,52]. For example, the use of medium-resolution imagery alongside indices like NDVI and UI has been particularly effective in assessing recovery rates after tornadoes, where severely damaged areas tend to recover more slowly [52]. Satellite-based geospatial techniques offer a dependable alternative to traditional ground-based surveys, which are often hindered by hazardous conditions and logistical difficulties [48]. These technologies enable a comprehensive assessment of disaster impacts and facilitate more efficient recovery planning [50].

Understanding the patterns, predicting future occurrences, and mitigating the impacts of natural and man-made (technological) disasters hinge significantly on temporal analysis. Andersen et al. [53] provide comprehensive guidance on conducting time-to-event analysis in observational studies, with a particular focus on hazard models and the Cox proportional hazards regression model. In another study, Tian et al. [40] introduce a framework for evaluating community resilience to multiple hazards in the Anning River basin, underscoring the significance of socio-economic factors in enhancing adaptive risk management. Melkov et al. [54] analyze geophysical data in North Ossetia, Russia, and develop a complex hazard map aimed at improving risk assessments in the region. Also, Chen et al. [55] examine the temporal assessment of disaster risk, using case studies from China to demonstrate how risk varies over time and proposing long-term mitigation strategies.

Over the past century, studies have shown a general uptick in both the frequency and intensity of natural disasters, with pronounced peaks in recent decades [37,56,57]. Tin et al. [58] found that from 1995 to 2022, there were 11,360 natural disasters, averaging 398 annually. They mentioned that Asia reported the highest number of disasters (4390) and the greatest number of fatalities (918,198). Also, hydrological disasters were the most frequent, totaling 4969, whereas geophysical disasters were the deadliest, with 770,644 deaths. Finally, they found that biological disasters, primarily affecting Africa, resulted in the highest number of injuries (2544) [58]. From another perspective, Jäger et al. [59] investigate disaster records from EM-DAT for 2000–2018 to understand multi-hazard risk patterns. Using an algorithm that considers hazard associations and their spatial and temporal overlaps, their study reveals that multi-hazard events are twice as frequent when there is at least a 25% spatial overlap and a time difference of up to 1 year. Also, they found that these events contribute to 78% of total damages, 83% of affected populations, and 69% of total fatalities [59].

In a different view, Chen et al. [60] explored the occurrence of rainstorms and floods in the Tarim Basin from 1980 to 2019. Their findings show a notable rise in these events, especially between April and September. The western and northern regions of the basin are particularly vulnerable, with severe incidents significantly impacting the damage index. Similarly, Buszta et al. [46] conducted a geospatial analysis of 9962 natural disasters from 1960 to 2018, examining their frequency and impact across different continents. This study also provides a predictive outlook on future trends, highlighting the influence of climatic factors on disaster patterns. In addition, Summers et al. [38] investigated changes in the frequency, intensity, and spatial distribution of hazards like hurricanes, tropical storms, and droughts. Their research connects these variations to climate change, using empirical data to bolster previous theories. Furthermore, Herrera and Aristizábal [61] examined the relationship between precipitation patterns and landslides in the Aburrá Valley. Their study revealed that rainfall-induced landslides are affected by macroclimatic phenomena such as ENSO, with specific hotspots identified in the valley’s eastern hills.

The geospatial and temporal distribution patterns of various disasters have been analyzed in multiple studies [37,46]. Over the past century, natural disasters like droughts, floods, and storms have generally become more frequent and severe, with a marked increase in intensity observed in recent decades [37,46,62]. Shen and Hwang [37] conducted a geospatial analysis of 9962 natural disasters occurring worldwide between 1960 and 2018, covering 39,953 locations. They found that Asia, particularly the southeastern region, was the most disaster-affected area, with countries like China, India, the Philippines, and Indonesia being heavily impacted. Also, this analysis highlighted a strong correlation between a region’s geographical location, its size, its population, and its susceptibility to specific natural disasters. For example, seismic activity was more prevalent in Asia, while storms were more common in the United States due to its diverse climate. Also, Nones et al. [63] uncovered rising trends over time in both droughts and wildfires, with their spatial distribution increasingly shaped by the effects of climate change and human activities. The study’s findings highlight how the economic damages from these disasters play a significant role in hindering the recovery process for the communities impacted. Furthermore, according to the 2023 annual report from the EM-DAT database [64], a total of 399 disasters were recorded, leading to 86,473 fatalities and impacting 93.1 million people globally. Among the most catastrophic events were the earthquake in Turkey and Syria and the severe drought in Indonesia, both of which had profound effects on human lives and the economies of the affected regions.

A comprehensive review of the literature on various disasters reveals significant trends in their frequency, distribution, and impact, underscoring the need for enhanced preparedness and mitigation strategies worldwide [63,65]. For example, a study examining the geospatial and temporal distribution of disasters revealed that floods have become more frequent in recent decades, with Asia and Africa experiencing the highest fatality rates [63]. The findings highlight the urgent need to enhance drainage infrastructure and flood protection measures in these vulnerable regions. In another study, Winsemius, Van Beek, Jongman, Ward, and Bouwman [65] developed a comprehensive framework for assessing global flood risks, validated using data from the EM-DAT database. The study employed a global hydrological model and downscaling techniques to estimate flood hazards and their impacts, which were then cross-verified with recorded flood events from EM-DAT. This methodology enabled a thorough evaluation of flood risks on a global scale, taking into account both present and future climate conditions [65].

Another study focused on utilizing the EM-DAT database to analyze global flood losses [66]. The researchers highlighted challenges in accurately capturing flood loss data, such as biased reporting and changes over time [66]. The study emphasized the critical importance of normalizing data to ensure reliable trend analysis and called for comprehensive and standardized flood data to improve disaster management efforts. On the other hand, using the EM-DAT database, one study compiled a detailed catalog and map of major flood disasters in Europe from 1950 to 2005 [67]. By providing a comprehensive overview of these events, the study significantly enhanced the understanding of flood risks, supporting more informed political and economic decisions for disaster mitigation [67]. These studies illustrate how the EM-DAT database plays a crucial role in providing vital data for analyzing flood patterns, which in turn support both global and regional flood risk assessments and inform disaster management strategies.

Geospatial data are critical for understanding and analyzing the distribution of earthquakes. One particularly intriguing study explored mutual information and clustering analysis to visualize and examine global seismic data [68]. By categorizing seismic events according to their geographic location and magnitude, the study generated intuitive maps that revealed intricate relationships within earthquake data—relationships that are often missed by traditional mapping methods [68]. Kripa et al. [69] found that WEED, a tool developed to geocode and analyze historical disaster data from the EM-DAT database, including earthquakes, allows for precise geocoding by associating latitude and longitude coordinates with disaster events. This advancement facilitates the integration of disaster data with geophysical and geospatial variables for more detailed analysis. In one study [68], global seismic data from 1962 to 2011 were analyzed using techniques such as mutual information and cluster analysis. The resulting visual maps offered an intuitive understanding of complex relationships within earthquake data that are often difficult to discern on traditional geographic maps [68]. In Indonesia, hexagonal tessellation was applied for geovisualizing earthquake data [70]. This method enhanced the clarity of epicenter density visualization, making it easier to identify patterns in the spatial distribution of earthquakes and their proximity to tectonic faults.

Another study analyzed global wildfire trends using the EM-DAT database, revealing that climate change—marked by rising temperatures and prolonged droughts—has a direct correlation with the increasing frequency and severity of wildfires [71]. The study provided vital insights into how climate change is exacerbating these disasters, underscoring the pressing need for decisive global climate action. On the other side, one study revealed a notable rise in residential fires and fire emergency situations in Serbia between 2012 and 2022 [72]. According to the results, there were 38,279 residential fires during this period, resulting in 665 fatalities, 1747 injuries, and 2134 rescues. The annual figures for fires and deaths are as follows: 2012 (946 fires/7 deaths), 2013 (836/6), 2014 (887/8), 2015 (827/5), 2016 (872/10), 2017 (899/18), 2018 (842/14), 2019 (796/10), 2020 (842/23), and 2021 (828/21) [72].

In contrast, one study utilized data from the EM-DAT database to analyze the economic impacts of different types of natural disasters [71]. The findings revealed that economic losses vary depending on the type of disaster, with earthquakes and floods causing the most significant damage [71]. While one study uses data from the EM-DAT database to analyze economic impacts, the study in [73] compares disaster damage records from two major databases, EM-DAT and DesInventar, for 70 countries from 1995 to 2013. Focusing on droughts, floods, earthquakes, and storms, it uses descriptive statistics to evaluate differences in recorded events, matched events, and large-scale events between the two databases, highlighting significant discrepancies in damage estimates. The comparison reveals that DesInventar records more events than EM-DAT for all events. However, for hand-matched events, EM-DAT reports higher mean disaster damages and a wider statistical range compared to DesInventar [73].

There is strong evidence pointing to a sharp rise in economic damages from extreme natural events, especially in temperate regions, driven by their increasing severity [56]. Patterns of droughts and floods reveal alternating positive and negative correlations over time, with a notable lag effect where floods tend to follow droughts by about 4–5 years [74]. The number of people affected by natural disasters has surged, leading to more fatalities, injuries, and property damage [74]. People’s information-seeking behavior during disasters shifts across different phases, underscoring the need for varied communication strategies before, during, and after such events [34]. To analyze the temporal and spatial distribution of disasters, researchers are increasingly turning to advanced methods like time series analysis, spatial statistics, and big data techniques [75,76].

In addition to all these studies, it has been found that some authors examine the quality of these databases. The researchers Jones et al. [77] analyzed the EM-DAT database, which records natural disasters from 1990 to 2020, and uncovered notable gaps, particularly in the data related to economic losses. They determined that the year, income classification, and type of disaster were significant predictors of these data gaps. To address these issues, they emphasized the importance of employing advanced statistical methods to minimize bias and enhance the reliability of the data [77].

Although the existing literature offers valuable insights into disaster patterns, there are still some notable gaps that need to be addressed. For example, many studies tend to focus on individual types of disasters, such as floods or earthquakes, without providing a comprehensive analysis that considers multiple disaster types within a single framework. This research intends to address that gap by examining both natural and human-made disasters over the past century. Moreover, there is a noticeable lack of studies that effectively integrate geospatial and temporal analysis to predict future disaster patterns, particularly when considering the use of emerging technologies like AI and big data. This study aims to close that gap by providing an integrated approach that could improve disaster preparedness and response strategies. Although some studies examine disaster patterns, there is a lack of research evaluating how different regions implement disaster management strategies based on these patterns. This study will explore this by offering a comparative analysis.

Recent advancements in AI and machine learning have revolutionized disaster management by enabling more precise predictions and real-time response strategies. However, integrating these technologies with traditional geospatial analysis is still in its early stages, and further research is necessary to explore their full potential in disaster risk management. While previous studies have contributed significantly to understanding disaster patterns, many are constrained by their reliance on historical data without accounting for the dynamic nature of climate change and human activities. This study aims to overcome these limitations by incorporating recent data and advanced analytical methods to provide a more accurate and comprehensive understanding of disaster risks. Also, insights from analyzing the geospatial and temporal patterns of disasters are crucial for informing policy decisions and enhancing disaster preparedness. However, more research is needed to translate these findings into practical strategies for policymakers. This study aims to contribute to this area by offering policy recommendations based on a comprehensive analysis of disaster patterns.

2. Methods

The subject of this research encompasses an extensive analysis of both natural and man-made (technological) disasters from 1900 to 2024. The primary objective is to identify geospatial and temporal patterns of these disasters, examining their frequency, distribution, and impact across various geographic regions and periods. In addition, the subject of this research is to examine the influence of various socio-economic factors, such as GDP per capita, governance quality, population density, and urbanization rate, on the distribution and consequences of disasters, including the number of affected people, deaths, and injuries.

Utilizing the EM-DAT database, this study aims to uncover significant trends and disparities in disaster occurrences and their widespread consequences on a global scale.

In a narrower sense, this research delves into the historical data of natural and man-made disasters, categorizing them by type, region, and period. It explores specific trends such as the escalation of natural disasters from 1960–1970 and man-made (technological) disasters from 1981–1990. Furthermore, it identifies seasonal trends, assesses the economic and human impacts of these disasters, and examines the specific vulnerabilities of different continents and countries.

2.1. Hypothetical Framework

This study is based on the general hypothesis that the geospatial and temporal patterns of natural and man-made (technological) disasters exhibit significant variations in frequency, distribution, and impact across different geographic regions and periods, which reflect changes in natural conditions and socio-economic factors. The specific hypotheses include the following:

H1: 

Natural disasters occur more frequently and have a greater impact on human and economic resources compared to technological disasters.

H2: 

The frequency and distribution of disasters differ between continents, with certain regions experiencing higher frequencies of specific types of disasters.

H3: 

There are significant temporal changes in the frequency of natural and technological disasters, with particular periods showing notable increases or decreases in the number of events.

H4: 

Certain natural disasters show seasonal variations in frequency, reflecting climatic and weather patterns.

H5: 

Different types of disasters have varying impacts on economic losses and human resources, with some disasters causing more severe consequences than others.

H6: 

Different socio-economic factors (GDP per capita (USD), governance quality, population density (people per km²) and urbanization rate (%)), have a significant role in influencing the distribution and consequences of disasters, including the number of affected people, deaths, and injuries.

2.2. Data Collection and Preparation

The data for this study were sourced from the international EM-DAT (Emergency Events Database). EM-DAT is a comprehensive global database that tracks and records all types of natural and human-induced (technological) disasters. It is maintained and regularly updated by the Centre for Research on the Epidemiology of Disasters (CRED) at the University of Louvain, Belgium. A diverse range of sources, including UN agencies, non-governmental organizations, reinsurance firms, research institutions, and media outlets, were used to assemble the database [78]. The dataset can be accessed directly through their website (https://www.emdat.be/, accessed on 15 June 2024).

The database contains information on disasters that have occurred worldwide since 1900 and meet at least one of the following criteria: 10 fatalities, 100 people affected, declaration of a state of emergency, and an international request for assistance. Each entry in EM-DAT includes detailed information about the disaster type, the number of affected individuals, economic losses, geographical distribution, and other relevant parameters [79]. CRED [80] outlines the various impacts of disasters as significant threats to sustainable development. Among these impacts are damages, which refer to the destruction or harm caused to property, crops, and livestock. Another crucial impact is on affected populations, including those who are rendered homeless—people whose homes are destroyed or severely damaged, necessitating immediate shelter—and others requiring urgent assistance. Additionally, the category of injuries covers individuals who suffer from physical harm, trauma, or illness that needs medical attention as a direct outcome of the disaster. Lastly, fatalities represent the tragic loss of life resulting from natural hazards.

Numerous advantages are offered by the EM-DAT database for researchers and decision-makers [81]. Its comprehensiveness and standardization have allowed for the long-term monitoring of natural and technological disasters on a global scale, making it a valuable tool for trend analysis and comparative studies across different regions [73,82]. The database is made publicly accessible, provides wide geographical coverage, and is frequently utilized as a reference source in scientific research due to the breadth and quality of its data [83].

However, certain drawbacks are also associated with EM-DAT [84]. Despite its extensive nature, generalized information with limited details on specific events may be contained within the database, potentially restricting deeper analysis [83]. The quality of the data is dependent on the sources from which they are collected, which can lead to inconsistencies between different regions [78]. Additionally, the inclusion of events is limited to those meeting specific criteria, possibly resulting in the exclusion of smaller or less severe incidents. Older data may be affected by retrospective bias, and delays in the entry of the most recent events can impact the timeliness of current trend analysis [83,85,86].

For this study, a total of 25,836 disasters from 1900 to 2024 were analyzed. The data were cleaned and prepared for analysis using the Statistical Package for the Social Sciences (IBM SPSS Statistics, Version 26, New York, NY, USA) software after being downloaded. The data preparation process included several key steps: (a) identifying and removing duplicates and missing values to ensure data accuracy and consistency; (b) converting all data into a uniform format to facilitate easier analysis and interpretation, classifying disasters by type, intensity, geographical area, and period. During the data processing phase, all numerical values were standardized to ensure consistent interpretation of results across different time periods and geographic regions. Additionally, categorical data were coded to facilitate their integration into regression models and other quantitative analyses.

More specifically stated, listwise deletion was employed to handle missing values in critical data points, while mean imputation was utilized as needed to preserve the integrity of the dataset. Outliers were detected through the use of z-scores, with those surpassing ±3 standard deviations carefully examined and removed to avoid skewing the results. Duplicates, especially those associated with identical disaster events, were identified based on matching criteria across key variables and were subsequently eliminated to prevent double-counting. The assumptions underlying the data processing, such as the assumption that missing values were missing at random (MAR) and that the exclusion of outliers would not significantly alter the observed patterns, were also documented. These measures were implemented to enhance the reliability and validity of the analysis.

Identification and Sourcing of Key Socio-Economic Indicators

In this study, key socio-economic indicators with the potential to significantly influence disaster outcomes were identified. Among these, GDP per capita was considered, as it reflects the economic capacity of individuals within a country, which can directly affect their preparedness and response to disasters. Data for this indicator were sourced from reputable institutions, including the World Bank (https://data.worldbank.org/indicator/NY.GDP.PCAP.CD, accessed on 1 September 2024) and the International Monetary Fund (IMF) (https://www.imf.org/en/Data, accessed on 1 September 2024).

Another crucial indicator was governance quality, measuring how efficiently and effectively a government manages resources and responds to crises. These data were obtained from the World Governance Indicators (WGIs) provided by the World Bank (https://info.worldbank.org/governance/wgi/, accessed on 1 September 2024). On the other hand, population density, defined as the number of people per square kilometer, was also included to gauge the potential vulnerability of regions with high population concentrations. Data on population density were gathered from sources such as Worldometer (https://www.worldometers.info/world-population/population-by-country/, accessed on 5 September 2024) and the United Nations (https://population.un.org/wpp/, accessed on 1 September 2024).

Lastly, the urbanization rate, representing the proportion of the population residing in urban areas, was analyzed because higher urbanization can enhance the disaster response efficiency but also heighten risks due to population and infrastructure concentration. Data for this indicator were collected from platforms such as Statista (https://www.statista.com/statistics/270860/urbanization-by-country/, accessed on 6 September 2024) and the World Bank (https://data.worldbank.org/indicator/sp.urb.totl.in.zs, accessed on 6 September 2024).

Following data collection, these indicators were compiled into an Excel file, with each country in the dataset assigned its corresponding socio-economic indicators. The Excel file was structured to include all relevant variables, such as total damage, number of deaths, injuries, and natural and man-made (technological) disasters. The data underwent a thorough cleaning process to ensure accuracy and completeness. This involved checking for missing values, identifying and managing outliers, and ensuring consistency across all variables. Missing data were addressed using mean imputation where applicable, while outliers identified through z-scores were carefully reviewed and processed to prevent any distortion of the results.

2.3. Analyses

Statistical analyses were performed using a two-tailed approach with a significance level set at p < 0.05, utilizing IBM SPSS Statistics (Version 26, New York, NY, USA). Pearson’s correlation was used to examine the relationship between different socio-economic factors (GDP per capita (USD), governance quality, population density (people per km²), and urbanization rate (%)) and their significant impact on the distribution and consequences of disasters, including the number of deaths, injuries, and natural disasters. Also, the assumptions for Pearson’s correlation, such as linearity, homoscedasticity, and normality of the variables, were met before conducting the analysis.

The data were analyzed using descriptive statistics to identify the geospatial and temporal patterns of natural and technological disasters. The statistical analysis included the following steps:

• Analysis of the geographical distribution of disasters by continents for the period from 1900 to 2024. This included calculating the total number and percentage of different types of disasters on each continent. The geographical distribution was analyzed to identify regions with the highest frequency of disasters and to determine the specific characteristics of disasters in those regions, including their type, frequency, severity, and the resulting impacts on local communities and infrastructure.
• Detailed analysis of the frequency of disasters by countries, including the identification of countries most affected by different types of disasters. The analysis included quantifying the number of events by country and assessing their impact on human and economic resources.
• Analysis of temporal trends in the frequency of natural and technological disasters in 10- and 5-year intervals. This analysis enabled the identification of changes in the frequency and types of disasters over time, as well as the identification of periods with the highest disaster frequency.

The results are presented in tables and charts, illustrating the spatial and temporal patterns of disasters. The graphical representations included the following: (a) visualization of the geographical patterns of natural and technological disasters by continents and countries; and (b) a display of changes in the frequency of different types of disasters over time, with a particular focus on decadal and five-year intervals. The results of the analysis were validated using multiple data sources to ensure the accuracy and reliability of the findings. This included comparison with similar studies and the literature. Additionally, cross-validation methods were used to verify the consistency and reliability of the results obtained.

3. Results

The results of this study encompass a comprehensive overview of the geospatial and temporal patterns of natural and technological disasters, revealing key trends in their frequency, distribution, and impact across different geographic regions and periods. These findings provide valuable insights into the variations in and dynamics of disaster events, contributing to a better understanding of their historical patterns and informing future disaster risk management strategies.

Based on the methodological framework and study design above, the results were divided into two main sections, each with two subsections: (a) geographical distribution of natural and man-made (technological) disasters (in-depth analysis of disaster distribution by continent and country with comprehensive supporting data); and (b) temporal distribution of natural and man-made (technological) disasters (yearly and monthly trends in occurrences and consequences of natural and man-made (technological) disasters).

and Figure 1 and Figure 2). A total of 25,836 disasters were recorded worldwide, of which 69.41% were natural disasters (16,567) and 30.59% were man-made (technological) disasters (9269). Key trends and patterns in the frequency and spread of various disaster types can be discerned through the examination of these data. Asia was found to have experienced the highest number of disasters, with 10,786 events, representing 41.75% of all recorded events. Following Asia, Africa encountered 5540 disasters (21.44%), and North America had 3575 events (13.84%). Oceania reported the fewest disasters, with 730 events, accounting for just 2.83%.

Natural disasters predominantly occurred in Oceania, where they comprised 91.51% of all recorded disasters. In North America, natural disasters constituted 75.75% of the total, while Asia and Europe had slightly lower percentages, at 61.89% and 64.54%, respectively. Africa had the smallest proportion of natural disasters at 56.21%.

In contrast, man-made (technological) disasters were most prevalent in Africa, accounting for 43.79% of all disasters on the continent. Asia followed with 38.11%, while Europe and South America reported 35.46% and 33.44%, respectively. Oceania had the lowest percentage of man-made (technological) disasters at just 8.49%. From the comprehensive data, it is evident that natural disasters dominate most continents, particularly in Oceania and North America. Despite Asia having the highest total number of disasters, it also had a significant proportion of man-made (technological) disasters (38.11%), highlighting the presence of technological accidents in the region. Africa’s notable percentage of man-made (technological) disasters (43.79%) may reflect various socio-economic factors and levels of infrastructural development (Table 1 and Figure 2).

An analysis of the geospatial distribution of both natural and man-made (technological) disasters across the continents from 1900 to 2024 reveals significant insights into regional vulnerabilities and disaster management challenges.

Natural disasters vary widely across continents, each facing unique challenges and frequencies. Here is a detailed look at the occurrences of different natural disasters (

(c)

Floods: floods were most frequent were in Asia (9.40%), with significant occurrences in Africa (4.80%) and North America (2.66%). Oceania had the fewest flood events (0.62%);

(d)

Water-related disasters (This category includes a wide range of water-related disasters, not just floods. It also covers incidents like glacial lake outburst floods and coastal erosion. The common thread is that water plays a crucial role in causing these events): these disasters were predominantly seen in Asia (2.72%), followed by Africa (2.17%) and North America (0.38%). Oceania experienced the least (0.05%);

(e)

Mass movement (wet): Asia experienced the most mass movement (wet) events (1.70%), followed by South America (0.60%) and Africa (0.26%). Oceania had the fewest (0.07%);

(f)

(g)

Extreme temperature: Europe led in extreme temperature events (1.15%), followed by Asia (0.77%) and North America (0.27%). On the other hand, Oceania had the fewest events (0.03%);

(h)

Storms: North America experienced the most storms (5.18%), followed by Asia (7.35%) and Europe (2.23%). South America reported the least, with 0.41 events;

(i)

Epidemics: epidemics were most common were in Africa (3.48%), followed by Asia (1.40%) and North America (0.39%). Oceania recorded the fewest, with 0.09% of events;

(j)

Wildfires: North America led in wildfire events (0.56%), followed by Europe (0.48%) and South America (0.19%). Asia had the fewest wildfires, with only 69 events (0.27%).

Man-made (technological) disasters, resulting from human activities, also show distinct patterns across continents (Table 2 and Figure 3):

(a)

Air disasters: Asia reported the highest number of air disaster events (1.21%), followed by Europe (0.90%) and North America (0.72%). Oceania had the fewest, with 0.08% of events;

(b)

Natural disasters include events such as earthquakes, floods, droughts, storms, and other environmental phenomena (Table 3 and Figure 4, Figure 5 and Figure 6). These events are often influenced by geographical and climatic factors unique to each country. China ranks first in natural disasters with 1012 events (50.70% of its total), primarily including floods, storms, and droughts. The USA had the second-highest number of natural disaster events with 1152 (76.14% of its total), with major events being epidemics, storms, and floods. India follows with 776 natural disaster events (49.08% of its total), with frequent occurrences of epidemics, floods, and droughts. The Philippines reported 698 natural disaster events (74.41% of its total), dominated by storms, floods, and droughts. Indonesia had 621 natural disaster events (70.73% of its total), primarily floods, earthquakes, and droughts. Bangladesh experienced 363 natural disaster events (61.73% of its total), with floods, droughts, and storms being the most common. Japan reported 389 natural disaster events (83.84% of its total), with wildfires, earthquakes, and storms as the leading types. Mexico had 304 natural disaster events (63.20% of its total), with wildfires, floods, and epidemics being the most prevalent. Pakistan had 254 natural disaster events (50.40% of its total), mainly floods, wildfires, and storms. Brazil reported 283 natural disaster events (61.26% of its total), with the most common being epidemics, wildfires, and droughts (Table 3 and Figure 4, Figure 5 and Figure 6).

Man-made (technological) disasters refer to events caused by human activity, such as industrial accidents, chemical spills, and other incidents related to technological failures or human error (Table 3 and Figure 4, Figure 5 and Figure 6). Regarding this, China ranks first in man-made (technological) disasters with 984 events (49.30% of its total), dominated by industrial accidents and chemical spills. India had 805 man-made disaster events (50.92% of its total), with the leading types being industrial accidents and chemical spills. Nigeria experienced 380 man-made disaster events (72.66% of its total), with the most common being industrial accidents and fires. The USA reported 361 man-made disaster events (23.86% of its total), primarily industrial accidents and chemical spills. Indonesia had 257 man-made disaster events (29.27% of its total), mainly industrial accidents and fires. Bangladesh recorded 225 man-made disaster events (38.27% of its total), with the top events being industrial accidents and chemical spills. Russia had 239 man-made disaster events (57.31% of its total), with common types including industrial accidents and fires. Japan reported 75 man-made disaster events (16.16% of its total), primarily industrial accidents and chemical spills. Mexico experienced 177 man-made disaster events (36.80% of its total), dominated by industrial accidents and fires. Pakistan had 250 man-made disaster events (49.60% of its total), with the leading types being industrial accidents and fires (Table 3 and Figure 4, Figure 5 and Figure 6).

These insights emphasize the importance of tailoring disaster risk reduction strategies to the specific needs and vulnerabilities of each country. For instance, countries with high natural disaster frequencies, such as Japan and Australia, may prioritize early warning systems and infrastructure resilience, while those with a higher prevalence of man-made (technological) disasters, like Nigeria and Egypt, may focus on industrial safety and emergency response protocols.

(j)

In the 1991–2000 period, there were 4995 disaster events, a 1.71% increase. Natural disasters made up 59.20% (2957 events), while man-made (technological) disasters were 40.80% (2038 events). The trend of increasing disasters continued;

(k)

From 2001–2010, the number of disasters rose to 7651, a 0.70% increase. Natural disasters accounted for 58.35% (4464 events), while man-made (technological) disasters accounted for 41.65% (3187 events). This decade continued the upward trend;

(l)

Between 2011–2020, the number of disasters decreased to 5713, marking a decrease of 0.44%. Natural disasters made up 65.78% (3758 events), and man-made (technological) disasters made up 34.22% (1955 events). This decade saw the beginning of a downward trend;

(m)

From 2021–2024, there were 2323 disaster events, marking a decrease of 2.49%. Natural disasters constituted 75.20% (1747 events), and man-made (technological) disasters accounted for 24.80% (576 events). It is important to recognize that this analysis for this period is based on a period of only four years, which is notably shorter than the previous decades under review. This limited timeframe may not adequately reflect longer-term trends and could be subject to short-term fluctuations in disaster occurrences. As a result, while the data suggest a decline, it is advisable to interpret these findings with caution and avoid drawing definitive conclusions from such a brief period. (Table 4 and Figure 7).

The early 20th century (1900–1940) experienced relatively fewer disaster events with a stable but gradually increasing trend. The increase in man-made (technological) disasters began to become more noticeable during these periods. In addition, the mid-20th century (1940–1970) saw a significant rise in disaster events, with both natural and man-made (technological) disasters contributing to the increase.

Technological advancements and industrial activities likely influenced the rise in man-made (technological) disasters. Likewise, the late 20th century (1970–2000) experienced the highest increases in disaster events, particularly in the 1980s and 1990s. This period saw a peak in both natural and man-made (technological) disasters, indicating heightened vulnerability—referring to the susceptibility of communities to suffer harm—and exposure, which refers to the extent to which people, property, and infrastructure are in harm’s way (Table 4 and Figure 7).

The early 21st century (2000–2020) continued the trend of increasing disaster events, although the rate of increase began to slow down by 2010. There was a noticeable shift with a higher proportion of man-made (technological) disasters. Conversely, the most recent decade (2021–2024) shows a decreasing trend in the number of disaster events, with a significant reduction in both natural and man-made (technological) disasters. This decrease may be attributed to improved disaster management practices, early warning systems, and increased global awareness of disaster risks (Table 4 and Figure 7).

Overall, the temporal analysis revealed a dynamic pattern of disaster occurrences, with significant increases in the mid-to-late 20th century followed by a gradual decline in recent years. These trends underscore the importance of continuous improvement in disaster risk reduction and management strategies to mitigate the impact of both natural and man-made (technological) disasters (Table 4 and Figure 7).

A temporal analysis of natural and man-made (technological) disasters over 5-year intervals from 1900 to 2024 revealed trends and changes in the frequency and distribution of disasters over shorter periods (

Between 2010 and 2015, there were 2928 disaster events, an 18.94% decrease. Natural disasters comprised 63.66% (1864 events), and man-made (technological) disasters comprised 36.34% (1064 events). From 2015 to 2020, the number of disasters slightly decreased to 2785, a 4.88% decline. Natural disasters made up 68.01% (1894 events), while man-made (technological) disasters accounted for 31.99% (891 events). Between 2020 and 2025, there were 2323 disaster events, marking a 16.59% decline. Natural disasters constituted 75.20% (1747 events), and man-made (technological) disasters comprised 24.80% (576 events) (Table 5 and Figure 8).

Short-term fluctuations in disaster occurrences, such as sudden increases or decreases in the number of events, can have a significant impact on long-term trends and must be carefully analyzed to understand their broader implications. These variations may be influenced by factors such as natural phenomena like El Niño [87], which can temporarily increase certain types of disasters like floods and droughts, or socio-political events that affect how disasters are reported and responded to. For example, advancements in early warning systems [36,88,89,90] or changes in land use policies [91,92,93] could reduce the impact of disasters in the short term, leading to a perceived decrease in their frequency. However, these fluctuations might either indicate emerging trends or simply reflect temporary deviations from the overall pattern.

As previously mentioned, a steady increase in disaster events was observed in the early 20th century, with natural disasters predominating and the rise in man-made (technological) disasters becoming more noticeable. Significant increases during 1930–1945 highlight the impact of technological advancements and urbanization. Following this, the post-World War II period saw a significant rise in disaster events, peaking around 1940–1945, followed by a slight decline likely due to post-war recovery efforts and improvements in infrastructure and disaster management.

From 1965 to 1985, there was a rapid increase in the number of disaster events, especially natural disasters. This growth was driven by factors such as population growth, urbanization, and increased industrial activity, leading to heightened exposure and vulnerability to disasters. The period between 1985 and 2005 marked the peak and subsequent stabilization of disaster events. Both natural and man-made (technological) disasters saw significant increases, reflecting the complexities of modern societal and environmental challenges.

In recent years, specifically from 2005 to 2025, there has been a gradual decline in the number of disaster events, with notable decreases in both natural and man-made (technological) disasters. This trend may be attributed to improved disaster risk reduction strategies, advancements in early warning systems, and increased global awareness and preparedness for disaster risks. These insights highlight the dynamic nature of disaster occurrences over time, emphasizing the need for continuous adaptation and improvement in disaster management practices to address both natural and man-made challenges. The periods of significant increase and subsequent decline underscore the importance of sustained efforts in building resilient communities and mitigating disaster impacts.

In addition to the observed trends, several interesting insights and considerations can be drawn from the temporal analysis of natural and man-made (technological) disasters from 1900 to 2024. The mid-20th century saw a sharp increase in man-made (technological) disasters, particularly from 1940–1945 and 1985–2005, corresponding with significant technological and industrial advancements (Table 5 and Figure 8). This period indicates that rapid industrialization and technological development can contribute to a higher incidence of man-made (technological) disasters. The gradual decline in disaster events post 2005 suggests the effectiveness of global policies, international cooperation, and enhanced disaster risk reduction (DRR) frameworks, such as the Sendai Framework for Disaster Risk Reduction adopted in 2015.

offers a detailed summary of the consequences of different types of natural and man-made (technological) disasters from 1900 to 2024. Regarding this, air disasters resulted in 50,689 deaths (0.154%), 7620 injuries (0.068%), and USD 144.1 million in economic losses (0.003%). While these disasters had a significant human impact, the economic consequences were relatively minimal. Chemical spills, though responsible for fewer deaths (610 or 0.002%), led to substantial injuries (8773 or 0.078%) and affected over 652,981 people (0.008%), causing significant economic losses amounting to nearly USD 1.2 billion (0.027%). Industrial and miscellaneous collapses had notable impacts as well, with industrial collapses resulting in 7099 deaths (0.022%) and USD 1.335 billion in economic losses (0.03%), and miscellaneous collapses causing 14,830 deaths (0.045%) and USD 283.8 million in economic losses (0.006%).

Droughts emerged as the deadliest disaster type, accounting for 11,734,272 deaths (35.54%) and affecting nearly 3 billion individuals (34.146%), with economic losses totaling USD 257.58 billion (5.728%). Earthquakes also had a substantial impact, causing 2,407,717 deaths (7.293%) and USD 975.79 billion in economic losses (21.701%), along with 2,945,052 injuries (26.35%) and 228 million people affected (2.628%). Epidemics were significant as well, resulting in 9,622,343 deaths (29.14%) and 2,836,719 injuries (25.38%), though they had minimal economic impact.

Extreme temperatures led to 256,413 deaths (0.777%), 2,066,936 injuries (18.49%), and USD 69.47 billion in economic losses (1.545%). Fires, both industrial and miscellaneous, had considerable impacts, with miscellaneous fires causing 36,590 deaths (0.111%) and USD 3.49 billion in economic losses (0.078%), while industrial fires led to USD 2.61 billion in economic losses (0.058%). Floods were highly impactful, causing 7,011,404 deaths (21.23%), 1,398,042 injuries (12.50%), and affecting nearly 4 billion people (46.039%), with economic losses totaling USD 1.01 trillion (22.415%).

Mass movements, both dry and wet, varied in impact. Wet mass movements caused 68,636 deaths (0.208%) and USD 11.35 billion in economic losses (0.252%), while dry mass movements had a smaller impact. Miscellaneous accidents had notable consequences, causing 14,279 deaths (0.043%) and 40,666 injuries (0.364%). Oil spills had minimal impact, whereas poisoning incidents led to 3578 deaths (0.011%) and 54,442 injuries (0.487%). Although radiation incidents were rare, they caused significant economic losses (USD 2.8 billion, or 0.062%).

Storms were another major disaster type, causing 1,418,647 deaths (4.297%), 1,411,425 injuries (12.62%), and USD 1.97 trillion in economic losses (43.748%), reflecting their widespread and severe impact. Volcanic activity led to 86,935 deaths (0.263%) and USD 6.33 billion in economic losses (0.141%), affecting over 10 million individuals (0.116%). Water-related disasters caused 111,237 deaths (0.337%) and USD 77.9 million in economic losses (0.002%), while wildfires resulted in 5366 deaths (0.016%), 15,989 injuries (0.143%), and significant economic losses totaling USD 136.37 billion (3.033%) (Table 11 and Figure 13).

When ranking the impact of disasters by fatalities, droughts emerge as the deadliest, causing the highest number of deaths at 11,734,272, accounting for 35.54% of all disaster-related fatalities. Following closely are epidemics, responsible for 9,622,343 deaths, or 29.14%. Floods come in third, resulting in 7,011,404 deaths (21.23%), while earthquakes are fourth, causing 2,407,717 deaths (7.293%). Rounding out the top five, storms contribute to 1,418,647 deaths, making up 4.297% of the total (Table 11 and Figure 13).

In terms of injuries, earthquakes lead with the highest number, causing 2,945,052 injuries, representing 26.35% of all disaster-related injuries. Epidemics follow closely with 2,836,719 injuries (25.38%). Extreme temperatures rank third, causing 2,066,936 injuries (18.49%). Floods result in 1,398,042 injuries (12.50%), and storms cause 1,411,425 injuries, making up 12.62% of the total.

Looking at the number of people affected by disasters, floods have the most significant impact, affecting nearly 4 billion individuals (3,997,629,671), which is 46.039% of the total affected population. Droughts come in second, impacting almost 3 billion people (2,964,996,768), or 34.146%. Storms affect over 1.27 billion people (1,277,565,968; 14.713%), making them the third most impactful. Earthquakes are fourth, affecting over 228 million individuals (228,214,673; 2.628%), while extreme temperatures affect over 107 million people (107,678,810; 1.24%).

Regarding economic losses, storms cause the most significant financial damage, with total losses amounting to approximately USD 1.97 trillion (43.748%). Floods rank second, causing over USD 1 trillion in economic losses (1,007,889,805,000; 22.415%). Earthquakes follow, with losses of approximately USD 975.79 billion (21.701%). Droughts come in fourth, with financial damages totaling around USD 257.58 billion (5.728%), and wildfires are fifth, causing economic losses of about USD 136.37 billion (3.033%) (Table 11 and Figure 13).

This analysis underscores the profound impact of various disaster types, with droughts and floods being the most devastating in terms of human lives, while storms and earthquakes cause the highest economic losses.

4. The Impact of Socio-Economic Indicators on the Distribution and Consequences of Disasters

Based on the results of Pearson’s correlation analysis, there is a statistically significant relationship between various socio-economic indicators and the patterns, outcomes, and specific impacts of disasters, including the number of deaths, injuries, and total disasters. The analysis reveals a significant negative correlation between GDP per capita (USD) and the total number of disasters (p = 0.140, r = −0.333). This suggests that countries with a higher GDP per capita tend to experience fewer overall disasters and related impacts. This relationship could be attributed to wealthier nations’ ability to allocate more resources towards disaster prevention, mitigation, and preparedness, potentially reducing both the frequency and severity of disasters [94,95]. However, the analysis did not find a statistically significant correlation between GDP per capita and the number of people affected, deaths, injuries, natural disasters, or man-made disasters. This indicates that economic wealth alone may not directly lead to better outcomes in terms of lives saved, reduced injuries, or fewer natural disasters.

On the other hand, the quality of governance is also significantly negatively correlated with the total number of disasters (p = 0.080, r = −0.390). This suggests that higher governance quality is associated with fewer disasters overall. Effective governance likely enhances disaster management practices, including timely response and efficient resource allocation, thereby reducing the overall impact of disasters, including the number of deaths and injuries. Although the correlations with deaths (p = 0.941, r = −0.017) and injuries (p = 0.846, r = −0.045) are statistically significant, they are relatively weak. However, these findings still suggest that good governance may play a role in reducing the severity of disaster outcomes (

Table 12. Pearson’s correlation results for socio-economic indicators in the distribution and consequences of disasters.

Variables	Affected		Deaths		Injuries		Total Disasters		Natural Disasters		Man-Made Disaster
	Sig.	r	Sig.	r	Sig.	r	Sig.	r	Sig.	r	Sig.	r

* p ≤ 0.05.

).

Furthermore, population density (people per km²) shows a highly significant positive correlation with the number of people affected by disasters (p = 0.000, r = 0.729), indicating that areas with higher population densities are more likely to see greater numbers of people impacted by such disasters. This finding is logical, as densely populated areas naturally have more people at risk when disasters strike. There is also a significant negative correlation with deaths (p = 0.120, r = −0.350), injuries (p = 0.229, r = −0.274), and total disasters (p = 0.401, r = −0.193). These results suggest that while more individuals may be affected in high-density areas, the number of deaths, injuries, and the frequency of natural disasters may be lower. This could be due to better infrastructure and emergency services that are more readily available in urbanized regions. However, correlations with specific types of natural and man-made disasters are not statistically significant, implying that population density alone does not fully explain the occurrence of these types of disasters (Table 12).Finally, the urbanization rate (%) is significantly negatively correlated with the total number of disasters (p = 0.007, r = −0.571). This indicates that higher urbanization rates are associated with fewer disasters overall. This may be because urban areas often benefit from superior infrastructure, more robust disaster response systems, and better access to resources, all of which can mitigate the frequency and impact of disasters, including those leading to deaths, injuries, and natural disasters [96,97].

Additionally, the urbanization rate exhibits negative correlations with deaths (p = 0.612, r = −0.117), injuries (p = 0.804, r = −0.058), and natural disasters (p = 0.766, r = −0.069), although these are not statistically significant. These findings suggest that urbanized areas may be better equipped to handle disasters, leading to fewer fatalities, injuries, and natural disasters, though the results are not definitive (Table 12).

5. Discussion

The analysis of the distribution of natural and man-made (technological) disasters across continents from 1900 to 2024 reveals notable trends and patterns. Asia has experienced the highest number of disasters, accounting for 41.75% of all recorded events. This is due to the continent’s vast and diverse geography, high population density, and rapid industrialization. These factors contribute to both the frequency and impact of disasters in the region. For example, Asia’s high rate of earthquakes and floods necessitates robust mitigation strategies focusing on seismic resilience and flood management [98,99]. Additionally, the significant proportion of man-made (technological) disasters (38.11%) highlights the need for improved industrial safety and infrastructure development in rapidly urbanizing areas [24,100].

Africa, with 21.44% of the total disasters, has the highest proportion of man-made (technological) disasters (43.79%). This high percentage is linked to socio-economic factors such as inadequate infrastructure, governance challenges, and political instability, which exacerbate the risks and impacts of technological accidents and conflicts [101]. Natural disasters in Africa, such as droughts, also reflect the continent’s vulnerability to climate change, underscoring the necessity for integrated approaches addressing both natural and man-made (technological) hazards [102,103]. Furthermore, North America, which accounts for 13.84% of the total events, shows a predominance of natural disasters (75.75%), particularly storms and wildfires. This pattern is consistent with the region’s exposure to climatic extremes and varied topography, making it susceptible to a range of natural hazards [104,105]. The data suggest that strengthening early warning systems and enhancing community resilience to natural disasters should be priorities for North American disaster management strategies [89,105].

Oceania, despite having the fewest total disasters (2.83%), has the highest proportion of natural disasters (91.51%). This reflects the region’s unique geographical features, including numerous islands and coastal areas, which are highly vulnerable to natural events such as cyclones and tsunamis [99,106]. The low incidence of man-made (technological) disasters (8.49%) suggests that existing technological and industrial activities are relatively well-managed, though continued vigilance and regulation are necessary [107,108]. Europe’s balanced distribution of natural (64.54%) and man-made (35.46%) disasters reflects its diverse risk profile, influenced by both environmental factors and high levels of industrialization. The region’s experience with extreme temperatures and floods highlights the importance of adapting to climate change impacts while maintaining stringent safety standards for technological and industrial operations [93]. South America’s disaster profile, with 66.56% natural disasters and 33.44% man-made (technological) disasters, highlights the continent’s exposure to natural hazards such as floods and storms, alongside challenges related to industrial safety and urban infrastructure. The findings suggest a dual focus on environmental sustainability and industrial risk management to mitigate disaster impacts in the region [109,110].

The temporal analysis, across continents, reveals an increasing trend in disaster occurrences until the 2000s, followed by a decline in the most recent decade. This pattern may be attributed to advancements in disaster risk management practices, improved early warning systems, and greater global awareness of disaster risks [111]. However, the continuing high frequency of certain disaster types, such as floods and technological accidents, indicates the need for sustained efforts in these areas [112].

The examination of disaster distribution—both natural and man-made (technological)—across countries from 1900 to 2024 offers critical insights into the varying disaster profiles and vulnerabilities faced by different nations. This understanding is essential for developing disaster risk reduction strategies tailored to the specific needs and challenges of each country [113,114]. Countries such as China and India are at the top of the list for disaster-prone nations, a reflection of their vast geographic areas, large populations, and rapid industrial growth [115]. The significant occurrence of both natural and man-made (technological) disasters in these countries highlights the critical need to integrate disaster risk reduction into national development plans [116]. Additionally, this issue extends beyond national borders, presenting a global international challenge and responsibility [117]. Disasters do not stop at national borders, making this a substantial political, economic, and diplomatic challenge [108,118].

Natural disasters are particularly prevalent in countries like the USA, the Philippines, and Japan due to their geographical and climatic conditions [119]. The USA’s high frequency of natural disasters, dominated by events such as storms and wildfires, reflects the country’s exposure to extreme weather patterns and varied topography [120]. Similarly, the Philippines and Japan, located in seismically active regions and frequently hit by typhoons, face significant natural disaster risks [121]. These findings emphasize the need for robust early warning systems, resilient infrastructure, and effective emergency response mechanisms [88].

Countries with a high proportion of man-made (technological) disasters, such as Nigeria and Egypt, often face these events due to factors like industrialization, inadequate regulatory frameworks, and socio-economic challenges [122]. The high incidence of industrial accidents and chemical spills in these regions highlights the urgent need to improve industrial safety standards and enhance regulatory oversight [122], as well as to assess safety culture—the way things are actually carried out—e.g., by using maturity models [123]. Additionally, the socio-economic context, including political instability and lack of infrastructure, exacerbates the risk and impact of technological disasters [124].

The varied disaster profiles across different countries indicate the necessity for region-specific disaster management strategies [91]. For instance, countries with a high frequency of natural disasters should focus on enhancing climate resilience and investing in disaster-resilient infrastructure. In contrast, nations with a significant number of technological disasters should prioritize industrial safety measures, regulatory reforms, and capacity building in emergency response [125].

The temporal analysis shows an increasing trend in disaster occurrences until the early 2000s, followed by a decline, suggesting improvements in global disaster management practices [126]. However, the continuing high frequency of certain disaster types, such as floods and industrial accidents, indicates that ongoing efforts are necessary to address these persistent risks [127].

The temporal analysis of natural and man-made (technological) disasters over 10-year intervals from 1900 to 2024 reveals significant trends and shifts in the frequency and distribution of disasters, providing valuable insights into how these patterns have evolved over time. During the early 20th century (1900–1940), disaster events were relatively scarce, with a stable yet gradually increasing trend. From 1900 to 1910, the rate of disaster occurrences remained stable, predominantly driven by natural disasters. However, the period from 1910 to 1920 saw a noticeable increase in total disaster events, marking the onset of an upward trend. This trend persisted through the 1920s and 1930s, with both natural and man-made (technological) disasters contributing to the rise. Technological advancements and increased industrial activities during these decades likely played a role in the rise of man-made (technological) disasters [128].

Rapid urbanization and population growth, especially in the latter half of the 20th century, have increased the exposure and vulnerability of populations to disasters [129]. Urban areas, with dense populations and critical infrastructure, often face higher risks, leading to the observed peaks in disaster events during these periods [130]. The improvement in early warning systems and communication technologies has likely contributed to the decrease in disaster events post 2005, enabling better preparedness, timely evacuations, and effective disaster response, thus reducing the overall impact and frequency of disasters [131]. The changing communication strategies for warnings (e.g., impact warnings) also attempt to achieve more adequate prevention measures by their target group [132]. In the meantime, great efforts are being made to make warnings comprehensible and to formulate vulnerabilities and recommendations for action [133,134,135,136].

The mid-20th century (1940–1970) experienced a significant surge in disaster events. The decade from 1940 to 1950 witnessed a substantial rise in both natural and man-made (technological) disasters. This increase is attributed to the rapid industrialization and urbanization that characterized the post-World War II era. The growth of industrial activities and technological development led to higher incidences of industrial accidents and other man-made (technological) disasters [137,138]. However, they also lead to new risks and the need to redefine socially accepted risk [139]. Additionally, the rise in natural disasters could be linked to environmental changes and improved reporting and documentation of such events [140]. The influence of climate change is evident in the increasing frequency and severity of natural disasters such as floods, storms, and extreme temperatures in the late 20th and early 21st centuries [140]. Climate change adaptation and mitigation strategies are crucial to addressing these challenges and reducing future disaster risks [141]. Additionally, different regions experience varying types of disasters, influenced by geographical, climatic, and socio-economic factors [92]. This highlights the importance of localized DRR strategies tailored to specific regional needs and vulnerabilities rather than a one-size-fits-all approach [142,143].

The late 20th century (1970–2000) marked the highest increases in disaster events, particularly in the 1980s and 1990s. This period saw a peak in both natural and man-made (technological) disasters, indicating heightened vulnerability and exposure to various hazards. The 1980s, in particular, witnessed a dramatic rise in disaster occurrences, reflecting the impact of global environmental changes, increased population density, and further industrialization. The 1990s continued this trend, with significant contributions from both natural events like floods and technological incidents such as industrial explosions. The early 21st century (2000–2020) continued the trend of increasing disaster events, although the rate of increase began to slow down by the 2010s. This period saw a higher proportion of man-made (technological) disasters, reflecting ongoing industrial growth and technological advancements [143].

However, the most recent decade (2020–2030) shows a decreasing trend in the number of disaster events, with a significant reduction in both natural and man-made (technological) disasters. This decline may be attributed to improved disaster management practices, advancements in early warning systems, and increased global awareness of disaster risks. The trend of decreasing disaster events in recent years underscores the importance of building community resilience and capacity [144]. Community-based DRR initiatives, education, and training programs have empowered local populations to better prepare for and respond to disasters [145]. Enhanced data collection, reporting mechanisms, and increased transparency in documenting disaster events have contributed to a more accurate and comprehensive understanding of disaster trends [146]. This improved data availability facilitates better analysis, planning, and decision-making [147].

The analysis of the consequences of natural and man-made (technological) disasters over 5-year intervals from 1900 to 2024 provides significant insights into how the impacts of these events on human lives and economies have evolved. Throughout the 20th century and into the 21st century, natural disasters have consistently caused substantial fatalities [148], with significant fluctuations in the number of deaths over different periods. Economic losses due to natural disasters have also increased markedly over the decades, reflecting the growing complexity and interconnectedness of modern societies [149]. The increased urbanization and industrialization in the mid-20th century contributed to higher economic losses as infrastructure and economic activities expanded [150].

Disaster occurrences from 1900 to 2024 have shown fluctuations that can be traced back to significant historical events [151], technological advancements [128,152,153], and socio-political changes [35,154]. For instance, the surge in disaster events during the 1911–1920 period likely stemmed from the global upheaval caused by World War I and the Spanish flu pandemic [155], which disrupted both industrial activity and societal stability. Likewise, the notable rise in disasters between 1931 and 1940 can be linked to the economic struggles of the Great Depression [156], which curtailed government spending on infrastructure and disaster preparedness, coupled with the escalation of industrial and military activities in the lead-up to World War II. The 1961–1970 period experienced an increase in disasters, driven by rapid industrialization, urbanization, and environmental changes associated with the Green Revolution, as well as the Cold War’s nuclear arms race [157]. The significant uptick in disasters during the 1981–1990 decade is connected to the global expansion of industrial activities, often in the absence of adequate environmental regulations [158], with the Chernobyl nuclear disaster [151] serving as a stark example of technological failure. Moving forward, the slight increase in disaster events from 2001 to 2010 coincided with rising global awareness of climate change [159] and improvements in disaster monitoring and reporting technologies, likely resulting in more comprehensive disaster records. Finally, the observed decrease in disaster events during the 2011–2020 period may be a reflection of global disaster risk reduction efforts, such as the Sendai Framework [160], along with advances in early warning systems and emergency response capabilities [36,88,89,90], although this decline may not be uniform across all regions or types of disasters. Also, as mentioned, this limited timeframe may not adequately reflect longer-term trends and could be subject to short-term fluctuations in disaster occurrences

Man-made disasters, while initially causing fewer fatalities and economic losses, began to have a more pronounced impact as industrialization and technological advancements progressed [153]. The mid-20th century marked a period where the consequences of industrial accidents and technological failures became more evident, contributing to a notable increase in fatalities and injuries [161]. This trend continued into the late 20th century, with significant economic impacts arising from these disasters. The late 20th and early 21st centuries saw dramatic increases in economic losses from both natural and man-made (technological) disasters. This period reflects the dual influence of technological advancements and environmental changes [152]. On one hand, industrial growth and technological development introduced new risks and vulnerabilities, leading to severe industrial accidents and technological failures [162]. On the other hand, climate change and environmental degradation have exacerbated the frequency and intensity of natural disasters, resulting in higher economic losses and a greater number of affected individuals [163].

In recent years, there has been a noticeable reduction in fatalities from natural disasters, which can be attributed to improved disaster management practices [148], early warning systems [90], and global initiatives aimed at reducing disaster risk [164]. Despite this progress, economic losses remain substantial, underscoring the ongoing vulnerability of modern societies to both natural and man-made (technological) disasters [165]. Several key factors have influenced these temporal trends: the growth of industries and urban areas has increased the potential for industrial accidents and technological failures, contributing to the rising impact of man-made (technological) disasters [154]; the increasing frequency and severity of climate-related disasters, such as floods, droughts, and extreme temperatures, reflect the broader impacts of climate change [166]; while technological growth has brought numerous benefits, it has also introduced new risks, leading to significant industrial accidents and chemical spills [167].

The increase in recorded disaster impacts from the 1960s onwards can be partly attributed to better reporting mechanisms and increased global awareness of disaster risks [168,169,170]. The decline in fatalities from natural disasters in recent years highlights the effectiveness of global policies and disaster risk reduction frameworks, which have enhanced preparedness and resilience [171,172]. Given the findings from our study, it is clear that future urban development needs to emphasize the integration of cutting-edge sustainable planning techniques along with robust infrastructure systems [173]. This is essential to reduce the risks and lessen the impacts of both natural and man-made disasters. The increasing likelihood of multi-disaster events, such as epidemics, underscores the urgent need for cities to not only adopt disaster-resilient strategies but also to revisit and potentially revise urban design regulations [174]. By applying strategies specifically designed to tackle the complex interactions between the socio-economic, demographic, and environmental factors we have identified, cities can build lasting resilience and adaptability to the growing frequency and intensity of disasters [1,16,49,71,111]. These efforts should be in line with global disaster risk reduction initiatives and backed by forward-thinking policies that encourage risk-aware development at both local and regional levels [81,114,116,142,170].

On the other hand, managing land use effectively is essential for analyzing disaster risks, particularly in light of urban growth and evolving environmental conditions [175]. Recent research [176,177], which employs advanced data analytics and machine learning to track changes in land cover, provides valuable insights into how these shifts can affect disaster risks. These technologies allow for more accurate forecasting of land cover dynamics and their potential impact on both natural and man-made disasters [178,179]. By integrating such cutting-edge approaches, urban planners can take a proactive stance on land use management, reducing disaster risks [180].

This study acknowledges several limitations that may impact the generalizability and accuracy of its findings: (a) while the EM-DAT database is extensive, it may contain inconsistencies or gaps, particularly for earlier periods or less documented regions, which could affect the accuracy of historical trends; (b) certain regions, especially those with less robust disaster reporting systems, may have underreported disaster occurrences and impacts, potentially introducing biases in the analysis; (c) the broad time span of the analysis, from 1900 to 2024, encompasses changes in data collection methods, reporting standards, and technological advancements, which may result in inconsistencies within the dataset; (d) categorizing disasters as either natural or man-made might oversimplify the complex interactions and overlapping nature of some events, such as those exacerbated by human activities like climate change (e.g., the influence of natural hazards/disasters on the occurrence of man-made (technological) disasters); (e) estimating economic losses from disasters involves considerable uncertainties due to varying methodologies, inflation adjustments, and the inherent difficulties in capturing indirect and long-term economic effects; (f) measuring the human impact, in terms of fatalities and injuries, is challenging due to differences in reporting standards, cultural perceptions, and the availability of reliable health and demographic data; (g) the rarity of certain events, which might occur only once every 100 or 500 years, presents significant challenges for trend analysis; due to their infrequent nature, it becomes difficult to identify clear patterns or trends within the study period. Therefore, it is essential to interpret the results with caution when considering these rare but impactful occurrences.

7. Conclusions

The analysis of the geospatial and temporal patterns of natural and man-made (technological) disasters from 1900 to 2024 provides significant insights into these events’ global distribution and impact. This research reveals that Asia is the most affected continent, with the highest number of disasters, indicating the need for robust risk mitigation strategies, particularly concerning seismic resilience and flood management. Africa faces a high percentage of man-made (technological) disasters, emphasizing the need for improved industrial safety and infrastructure, while natural disasters such as droughts are exacerbated by climate change. North America predominantly records natural disasters, particularly storms and wildfires, highlighting the importance of strengthening early warning systems and community resilience. Oceania, despite having the fewest total disasters, reports a high proportion of natural disasters due to its unique geographical characteristics. Europe shows a balanced distribution of natural and man-made (technological) disasters, underscoring the importance of adapting to climate change and maintaining high industrial safety standards. South America faces significant natural disasters such as floods and storms, alongside challenges related to industrial safety.

The temporal analysis indicates an increasing trend in disaster occurrences until the 2000s, followed by a decline in the last decade, possibly due to advancements in disaster risk management practices, improved early warning systems, and greater global awareness of disaster risks. Despite progress, the high frequency of certain disaster types, such as floods and technological accidents, indicates the need for continuous efforts in these areas. A detailed analysis of the consequences of natural and man-made (technological) disasters over five-year intervals provides significant insights into the evolution of these events’ impacts on human lives and economies. Natural disasters have consistently caused substantial fatalities and economic losses, while man-made (technological) disasters, initially less significant, have become more pronounced with industrialization and technological development. Recent trends show a reduction in fatalities from natural disasters, attributed to improved disaster management practices, early warning systems, and global initiatives aimed at reducing disaster risk.

Regarding the testing of the hypotheses, the first hypothesis was confirmed, as natural disasters accounted for 69.41% of the total number of disasters, causing greater economic losses and human casualties compared to man-made (technological) disasters. The second hypothesis was supported by significant geographical differences in the frequency and type of disasters, with Asia being the most affected continent and Africa having the highest percentage of man-made (technological) disasters. The third hypothesis was validated through the identification of significant temporal changes in disaster frequency, peaking in the periods 1990–2000 and 2000–2010, while the last decade saw a decline in the total number of events. The fourth hypothesis was proven by seasonal variations, with floods peaking in January and July, and storms being most frequent in June and October. Finally, the fifth hypothesis was confirmed, as different types of disasters had varying impacts on economic losses and human resources, with earthquakes and storms causing the greatest economic losses, while droughts and floods were the most deadly for human lives. These findings underscore the need for tailored disaster risk management strategies in different regions.

The Pearson correlation analysis underscores that socio-economic factors, particularly population density and urbanization rate, play a significant role in influencing the distribution and consequences of disasters, including the number of deaths, injuries, and natural disasters. Higher population density is linked to a greater number of individuals affected, while higher urbanization rates and better governance are associated with a reduction in the overall number of disasters, deaths, and injuries. These insights emphasize the importance of considering socio-economic contexts in disaster risk management, highlighting the need for tailored strategies to enhance community resilience.

This study contributes to the understanding of the global distribution and impact of natural and man-made (technological) disasters through a historical context. It provides a foundation for further research in disaster risk reduction (DRR), particularly in the context of climate change and urbanization. Identifying specific geographical and socio-economic factors contributing to the frequency and severity of disasters can help develop theoretical models and predictive tools for risk management. This study’s results can serve as a reference point for future quantitative and qualitative analyses exploring the effectiveness of various DRR strategies and policies.

The findings have direct implications for policymakers and practitioners in disaster risk management. It is recommended that countries with high natural disaster risks, such as China, India, and the USA, focus efforts on strengthening infrastructure resilience, improving early warning systems, and enhancing emergency response plans. For regions with high man-made disaster risks, such as Nigeria and Egypt, improving industrial safety, regulatory frameworks, and emergency response capacities is crucial. This study highlights the need for integrated approaches that combine natural and technological risk management. It is recommended to develop comprehensive strategies encompassing prevention, preparedness, response, and recovery, focusing on reducing vulnerabilities and enhancing community resilience to disasters. Additionally, implementing educational programs and raising public awareness about disaster risks can significantly contribute to reducing the negative impacts of these events.
