What is a disaster?
The term disaster is said to be originated from the French word "Desastre" which is a combination of two words 'des' meaning bad and 'aster' meaning star. Thus the term refers to 'Bad or Evil star'.
A disaster can be defined as "A serious disruption in the functioning of the community or a society causing wide spread material, economic, social or environmental losses which exceed the ability of the affected society to cope using its own resources". A disaster is a result from the combination of exposure to hazard, vulnerability and insufficient capacity or measures to reduce the potential chances of risk. A disaster happens when a hazard impacts on the vulnerable population and causes damage, casualties and disruption.
