Natural hazards

A natural hazard[1] is a natural phenomenon that might have a negative effect on people or the environment. Natural hazard events can be grouped into two broad categories,[2] which are geophysical hazards[3][4] encompass geological and meteorological phenomena such as earthquakes, volcanic eruption, wildfire, cyclonic storms, flood, drought, and coastal erosion. Biological hazards can refer to a diverse array of disease and infestation.

Many geophysical hazards are related;[5] for example, submarine earthquakes can cause tsunamis, and hurricanes can lead to coastal flooding and erosion. Floods and wildfires can result from a combination of geological, hydrological, and climatic factors. It is possible that some natural hazards are intertemporally correlated as well.[5][6] An example of the division between a natural hazard and a natural disaster is that the 1906 San Francisco earthquake was a disaster, whereas living on a fault line is a hazard. Some natural hazards can be provoked or affected by anthropogenic processes (e.g. land-use change, drainage and construction).[7]
