Natural disasters Essay
...﻿ Natural Disasters We have all seen the awful effects of a flood or an earthquake - if we’re lucky only on the news. About 75 percent of the world’s population live in areas affected at least once by earthquake, tropical cyclone, flood or drought between 1980 and 2000 (Reducing Disaster Risk UNDP report, 2005). What causes natural disasters ? First we need to get a bit technical. Natural hazards and natural disasters may sound like the same thing but there is a small but vital difference. Natural hazards are things like earthquakes, volcanic eruptions, landslides, tsunamis, floods and drought - any physical event that happens naturally. They are caused by changes in the atmosphere, the earth’s surface or the sea or other body of water. They can happen quickly, called a rapid onset hazard, or build up gradually, called a slow onset hazard. They can happen over smaller, local areas or affect countries, regions or the whole world – some even happen in space, on the sun for example.
