Geohazards Monitoring Assessment: Earth-Observation Techniques

Dear Colleagues,

With the increase in extreme weather and the expansion and intensity of human activities, the impact of geological disasters on human beings has become more and more remarkable. Frequently and widely distributed geohazards and hazard chains are a major threat to the sustainable development of human production and life. Earth-observation technology has unique advantages in long-time series regional data accumulation, multi-parameter high-frequency monitoring, multi-factor comprehensive analysis, and emergency relief support. There have been many contributions to geohazard detection and characterization. However, considering the geohazard conditioning factors of geological, geomorphological, and hydrological predictors, and also the geohazard-triggering factors of the short-term cumulative rainfall, antecedent rainfall, rain infiltration, and soil hydrological conditions, the time evolution monitoring and permanent real-time early warning system of geohazards still need strengthening. With the introduction of new technologies and methods such as 3S technology and intelligent algorithms, monitoring and assessment studies are necessary to adapt to the rapid development of Earth observation technology. The aim of this research topic is to explore the application of Earth observation systems in geohazard monitoring and risk assessment. We welcome research topics on time evolution monitoring, early warning systems, and hazard assessment of different types of single geohazards or multiple geohazards. We also welcome a wider range of geohazard-related research to join our Special Issue.

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. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
