Seminar on Disaster management

Emergencies, Disasters, and Catastrophes are not gradients, they are separate, distinct problems that require distinct strategies of response[citation needed]. Disasters are events distinguished from everyday emergencies by four factors: Organizations are forced into more and different kinds of interactions than normal; Organizations lose some of their normal autonomy; Performance standards change, and; More coordinated public sector/private sector relationships are required.

Catastrophes are distinct from disasters in that: Most or all of the community built structure is heavily impacted; Local officials are unable to undertake their usual work roles; Most, if not all, of the everyday community functions are sharply and simultaneously interrupted, and; Help from nearby communities cannot be provided. Assets are categorized as either living things, non-living things, cultural or economic. Hazards are categorized by their cause, either natural or human-made. The entire strategic management process is divided into four fields to aid in identification of the processes.

The four fields normally deal with risk reduction, preparing resources to respond to the hazard, responding to the actual damage caused by the hazard and limiting further damage (e.g., emergency evacuation, quarantine, mass decontamination, etc.), and returning as close as possible to the state before the hazard incident. The field occurs in both the public and private sector, sharing the same processes, but with different focuses.
