Disasters are the inconvenient situations faced by humans, especially which cause loss of life and resources. Bringing back the normalcy after a disaster has happened or reducing its effect while it is in place is called disaster management.
Disasters can be divided in two types, MAN MADE & NATURAL.
The man-made disasters like terrorist attacks, destruction caused by wars and nuclear explosions are very hard to manage.
Natural disasters like earthquake, flood, volcano eruption, cyclones are forms of natural disasters. Various organisations of the world like meteorological departments try to find the timing of the occurrence of these disaster so that their effect can be tackled and minimised.
