Remote Sensing in Geologic Hazards and Risk Assessment

Dear Colleagues,

Geologic hazards such as landslides, rockfalls, debris flows, and earthquakes have presented many engineering geology and geotechnical challenges in the design, building, and maintenance of mountainous infrastructures in recent decades. As a result, the investigations of geologic hazards have gained much attention in the geosciences field, due to their likelihood of causing human casualties and severe economic damage. The activity of geologic hazards and the rough terrain may limit or preclude the collection of geological data necessary to characterize geologic hazards when traditional survey methods are employed. The study of geologic hazards has advanced significantly as a result of the rapid development of remote sensing and GIS technologies. Multi-sensor, multi-platform, and multi-temporal datasets and techniques can improve the quality and quantity of remotely sensed data, allowing us to better understand the behavior and geomorphic evolution of geologic hazards. However, it has been challenging to successfully develop effective early identification and warning systems for geological hazards. Therefore, carrying out a risk assessment and stability analysis for geologic hazards has important theoretical significance and application value, contributing to the establishment of an early warning system and implementing control measures for geologic hazards. This Special Issue aims to showcase the advances in the application of state-of-the-art remote sensing techniques, numerical modeling approaches, and their combination for the characterization, monitoring, simulation, and risk assessment of geologic hazards in different environments. Potential topics include but are not limited to the following:

• Spatiotemporal analysis of geologic hazards;
• Field investigations, descriptions, and formation mechanism analysis of geologic hazards;
• Applications of state-of-the-art remote sensing techniques in geologic hazards;
• Risk assessment methods for geologic hazards on a regional scale;
• Applications of advanced Earth observation technologies in geologic hazards;
• In-depth controlling factor analysis of geologic hazards;
• Construction of early warning system and reinforcement measures for geologic hazards;
• New techniques and materials for disaster risk reduction.
