災害管理
Emergency management has four distinct phases that create the management process. These phases are mitigation, preparation, response, and recovery. While each phase has a distinct role in the emergency management process, there are aspects of each that interconnect with others. A management process without any one of the four phases could be deemed incomplete and inadequate. Mitigation is easily defined as prevention. Preparedness is the act of changing behaviors or processes to reduce the impact a disaster may have on a population or group. Response is assembling teams or units of emergency service to the area of disaster. Finally, recovery aims to restore the area affected by the disaster to its condition prior to the disaster.
