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.
A natural hazard [18] is a natural phenomenon that might have a negative effect on humans and other animals, or the environment. Natural hazard events can be classified into two broad categories: geophysical and biological. [19] Natural hazards can be provoked or affected by anthropogenic processes, e.g. land-use change, drainage and ...
The type of managed retreat proposed depends on the location and type of natural hazard, [4] [5] [6] and on local policies and practices for managed retreat. In the United Kingdom, managed realignment through removal of flood defences is often a response to sea-level rise exacerbated by local subsidence.
Coastal hazards are physical phenomena that expose a coastal area to the risk of property damage, loss of life, and environmental degradation.Rapid-onset hazards last a few minutes to several days and encompass significant cyclones accompanied by high-speed winds, waves, and surges or tsunamis created by submarine (undersea) earthquakes and landslides.
A natural disaster is the very harmful impact on a society or community after a natural hazard event. Some examples of natural hazard events include avalanches, droughts, earthquakes, floods, heat waves, landslides - including submarine landslides, tropical cyclones, volcanic activity and wildfires. [19] Additional natural hazards include ...
Natural hazards can be influenced by human actions in different ways and to varying degrees, e.g. land-use change, drainage and construction. [17] Humans play a central role in the existence of natural hazards because "it is only when people and their possessions get in the way of natural processes that hazard exists". [5]

Example of a hazard map. A hazard map is a map that highlights areas that are affected by or are vulnerable to a particular hazard. They are typically created for natural hazards, such as earthquakes, volcanoes, landslides, flooding and tsunamis. Hazard maps help prevent serious damage and deaths. [1]
