Disaster Time Phases
Disaster Time Phases : "There are several discernible phases in the history of any disaster. The pre-disaster phase is the everyday situation in the community. A pre-impact phase begins with the earliest sign of possible danger and is the time between initial warning and actual impact. Warning may be official as in the case of a weather bulletin, or spontaneous such as the spotting of a gas leak by a passerby. The impact phase is that period when the disaster actually strikes?this period may be of limited or long duration, from a few minutes (tornado) to several weeks or more (flooding). The emergency phase is the period of response to the immediate demands presented by the agent. Recovery is the final phase and includes attempts to mitigate any longterm effects of the disaster agent and return the community to normal, everyday conditions".
