A geohazard is a geological source of danger.
There are many different types of geohazard with different natural and artificial processes causing them to occur. However, they all have the potential to create problems for development of the human environment and threats to the safety and well-being of people. Geohazards can develop quickly (seconds or minutes) in response to the processes that drive them, or take tens, hundreds, or thousands of years to develop to a point where they pose a danger. They are found in most parts of the world, including marine and fluvial environments. Their existence is an indication of the continuing evolution of the solid Earth as they are part of the processes by which rocks are eroded and moved and then recreated by deposition, burial, alteration as a...
