DISASTER MANAGEMENT CYCLE
The disaster cycle or the disaster life cycle consists of the steps that emergency managers take in planning for and responding to disasters. Each step in the disaster cycle correlates to part of the ongoing cycle that is emergency management. This disaster cycle is used throughout the emergency management community, from the local to the national and international levels.
The first step of the disaster cycle is usually considered to be preparedness although one could start at any point in the cycle and return to that point before, during, or after a disaster. For the sake of understanding, we will start with preparedness. Prior to a disaster’s occurrence, emergency manager will plan for various disasters which could strike within the area of responsibility. For instance, a typical city located along a river would need to plan for not only flooding but also hazardous material accidents, large fires, extreme weather (perhaps tornadoes, hurricanes, and/or snowstorms), geologic hazards (perhaps earthquakes, tsunamis, and/or volcanoes), and other applicable hazards. The emergency manager learns about past disasters and current potential hazards and then begins to collaborate with other officials to write a disaster plan for the jurisdiction with appendices for specific hazards or special types of response scenarios. Part of the planning process is the identification of human and material resources needed during a specific disaster and obtaining information about how to access those resources, whether public or private. If specific material resources are needed to have on hand prior to a disaster, those items (such as generators, cots, decontamination equipment, etc.) are obtained and stockpiled in appropriate geographic locations based on the plan.
