Two types of demands are made in disasters. Demands of the first type which are generated by the disaster agent as it strikes the community are called agent-generated demands. In responding to these demands, the community will in turn be confronted with a new and more general set of demands called response-generated demands. Both sets of demands must be given consideration in developing a comprehensive disaster-response plan. Agent-generated demands include warning, preimpact preparations, search and rescue, care of the injured and removal of the dead, welfare demands, restoration of essential community services, protection against continuing threats, and community order. Response-generated demands include communication, continuing assessment, mobilization and utilization of human and material resources, coordination, and control and authority. Disaster research studies have identified organized planning as the primary means of successfully aiding disaster victims. Bibliography
