Huge landslide at La Conchita, 1995. A geologic hazard or geohazard is an adverse geologic condition capable of causing widespread damage or loss of property and life. [1] These hazards are geological and environmental conditions and involve long-term or short-term geological processes.
The factors that have been used for landslide hazard analysis can usually be grouped into geomorphology, geology, land use/land cover, and hydrogeology. Since many factors are considered for landslide hazard mapping, GIS is an appropriate tool because it has functions of collection, storage, manipulation, display, and analysis of large amounts ...
Debris flows can be more frequent following forest and brush fires, as experience in southern California demonstrates. They pose a significant hazard in many steep, mountainous areas, and have received particular attention in Japan, China, Taiwan, USA, Canada, New Zealand, the Philippines, the European Alps, Russia, and Kazakhstan.
Seismic microzonation is defined as the process of subdividing a potential seismic or earthquake prone area into zones with respect to some geological and geophysical characteristics of the sites such as ground shaking, liquefaction susceptibility, landslide and rock fall hazard, earthquake-related flooding, so that seismic hazards at different locations within the area can correctly be ...
The United States Geological Survey National Volcanic Threat Assessment is a report containing a ranked list of active volcanoes in the United States posing hazardous risks to the American population. [1] The report was published by the United States Geological Survey in 2005 [2] and revised in 2018. [3]
Environmental hazard identification is the first step in environmental risk assessment, which is the process of assessing the likelihood, or risk, of adverse effects resulting from a given environmental stressor. [6] Hazard identification is the determination of whether, and under what conditions, a given environmental stressor has the ...
This category is a loose grouping of natural hazards caused by movements or eruptions of land and secondary movements of water. These are here distinguished from Category:Weather hazards and other natural hazards: Category:Natural hazards.
