Special Issue Information
Dear Colleagues,
This Special Issue of Geosciences aims to gather original research articles, reviews, and technical notes on Natural Hazard assessment, applied to geological systems, based on the collection of data and/or numerical modelling derived from in situ and remote sensing (including from satellites) measurements.
In volcanic systems, the passive release of fluids from hydrothermal and magmatic sources marks the inter-eruptive periods. The diffuse soil degassing activity can generate gas hazard, asphyxiation, or poisoning, allowing the accumulation of harmful gases, especially under low wind conditions or in depressed areas. In addition to the catastrophic events, attention would be focused on the long-term (active and passive) release which may affect human health and may increase the knowledge in terms of forecasting. Critical gas hazard conditions occur in volcanic areas: large plumes, weakly degassing sites, fumarolic fields, mud volcanoes, but they can occur also in other geological systems. Studies focusing on the natural gas quantification and dispersion numerical modelling are welcome. The articles must give an important contribution to improve the monitoring (that is not easy) and the forecasting of natural events.
In addition, also the ash release and dispersal are crucial considering the effects of ash amounts into the high troposphere-low stratosphere. Characterizing the pyroclastic fragments injected into the atmosphere during volcanic eruptions is crucial to the forecasting of plume dispersal. The main hazards connected to the tephra release are: 1) the fast in-plume heterogeneous reactions and 2) the deposition and the leaching of fresh-fallen ash.
This Special Issue will examine the state of the art of monitoring, including the complete range of aspects: the acquisition of the data, its interpretation, its application to generate models and forecasts. We would appreciate multidisciplinary research studies, including expertise from various fields of physics, chemistry, and geology, and as well as computer science and statistics. We welcome papers aiming to understand natural events using in situ, proximal, and remote sensing observations, laboratory analyses, numerical modelling, geophysical/geochemical techniques.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
