Abstract from DBPedia
    A natural hazard is a naturally occurring event that might have a negative effect on people or the environment. Natural hazard events can be grouped into two broad categories. Geophysical hazards 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 interrelated; 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. A concrete 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.
