It is an ongoing process by which governments, civil (and military) society plan for and reduce the impact of disasters, react during and immediately following a disaster, and take steps to recover after a disaster has occurred.[1][2] There are variations to the cycle but the most common version is the 4 phases of disaster cycle:[3]
Mitigation: involves implementing measures for preventing future threat of disaster and/or minimizing their damaging effects of unavoidable threat. It requires hazard risk analysis and the application of strategies to reduce the likelihood that hazards will become disasters, such as flood-proofing homes or having flood/fire insurance, following safety standards of building materials and appliances. This phase (and the whole cycle disaster management cycle), includes the shaping of public policies and plans that either modify the causes of disasters or mitigate their effects on people, property, and infrastructure.
Disaster preparedness:preparedness efforts include plans or preparations made in advance of an emergency that help individuals and communities get ready to either respond or to recover. It aims to achieve a satisfactory level of readiness to respond to any emergency situation through programs that strengthen the technical and managerial capacity of governments, organizations, and communities. These measures can be described as logistical readiness to deal with disasters and can be enhanced by having response mechanisms and procedures, rehearsals, developing long-term and short-term strategies, public education and building early warning systems. The preparations may include the stocking of reserve food and water, the gathering and screening of willing community volunteers, or citizens education & evacuation plan, holding disaster drills, and installing smoke detectors, mutual aid agreements, development of hospital disaster plans, emergency medical service plans, etc.
Disaster response: Disaster response work includes any actions taken in the midst of or immediately following an emergency, including efforts to save lives and to prevent further property damage. Ideally, disaster response involves putting already established disaster preparedness plans into motion. It’s what the public typically thinks of when imagining a disaster: Flashing lights, evacuation, search and rescue, and sheltering victims. Healthcare and psychosocial intervention response starts here. The focus in the response phase is on meeting the basic needs of the victims until sustainable community has been achieved.This phase may still continue even when recovery phase can already be started.
Disaster recovery: Recovery involves restoring, rebuilding, and reshaping the impacted area. It starts after damages have been assessed and adequate response effort is achieved and on-going. It involves actions to return the affected community to its pre-disaster state or better. As the emergency is brought under control, the affected population is capable of undertaking a growing number of activities aimed at restoring their lives and the infrastructure that supports them. Recovery activities continue until all systems return to normal or better. These measures, both short and long term, aim to return vital life-support systems to minimum operating standards; such as temporary housing, public information, health and safety education; continued health monitor and care, reconstruction of vital facilities; counseling programs; grants, and it may include economic impact studies.
In reality, there is no clear distinct point at which these 4 phases change through out the cycle. There can be opportunities during the recovery period to improve prevention and increase preparedness, thus reducing vulnerability. Recovery can start when the response phase is still on-going. A smooth transition from recovery to mitigation is ideal. The disaster management cycle is just the typical flow of events. When disaster strikes response is prioritized, mitigation can’t start yet. When disaster hasn’t yet happened, mitigation - preparedness start and there is nothing to respond yet. But the lines between each following cycles blur.
To some degree, the cycle flows in such flexible order.
