Description

A flood is an overflow of an expanse of water that submerges land, or a temporary covering by water of land not normally covered by water. The word may also be applied to the inflow of the tide. Flooding may result from the volume of water within a body of water; river or lake, which overflows. An earthquake or a quake, tremor or temblor, is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. The seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. In meteorology, a cyclone or hurricane is an area of closed, circular fluid motion rotating in the same direction as the Earth. A wildfire/ bushfire/ forest fire/ desert fire is any uncontrolled fire in combustible vegetation that occurs in the countryside or a wilderness area. A wildfire differs from other fires by its extensive size, the speed at which it can spread out from its original source, its potential to change direction.
