Disaster Management

  Some of the natural Disasters that have a huge impact on the mankind are: Earthquakes An earthquake is a sudden tremor or movement of the earth’s crust, which usually originates at or below the surface. The outer layer of the earth is solid and is divided into many sections known as plates. These plates, float over the molten magma that flows beneath the earth’s crust. Many of the earthquakes occur on the edges of these plates along fault lines where the plates collide or try to slide past each other. Apart from natural causes like the movement of the Earth’s tectonic plates and volcanic eruptions, there are other man-made causes of earthquakes. These include vibrations caused by big rocks falling down hills because of erosion, hollow parts of mines falling down due to dissolution of minerals by water and, in the present times, due to nuclear explosions. The point of origin of the earthquake within the crust or mantle is called the seismic focus. Since the focus is often deep below t

  A disaster is a destructive event that occurs suddenly and involves loss of life and property. Disasters can be of two types, natural and man-made. Earthquakes, volcanic activity, tsunamis, floods, cyclones, landslides, avalanches and droughts are natural disasters and man has no control over them. The man-made disasters are triggered by human beings. Some of the man-made disasters are: bomb explosions, terrorism, war or civil war, leakage of poisonous chemicals, breach in dams, air or water pollution, industrial accidents and epidemics. Whether natural or man-made, these disasters hamper normal routine of the society and usually affect a large number of people. Disasters can also lead to huge loss of life and property. When a disaster strikes a society, external help is usually needed in the form of aid to cope with its impact. Disaster Management refers to the measures taken for the safety and protection of life and property from natural or man-made disasters. This means being prep
