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 prepared for disasters, fighting disasters effectively, ensuring the safety of life during disasters and helping in rebuilding society after the disaster.
