A disaster is a sudden, catastrophic event that severely disrupts the normal functioning of a community or society, causing widespread human, material, economic, or environmental losses that exceed the affected community's ability to cope using its own resources. Disaster Management is a continuous, integrated process of planning, organizing, coordinating, and implementing measures necessary for risk reduction, emergency response, relief, and post-disaster rehabilitation.
