Before this, I already mention a bit about disaster and give some example of it. But, do you know exactly what is disaster. In my mind, i thought that disaster is some phenomena that causes destruction. But do you know that as long as it doesn't needs any external help, it is not consider as disaster.
According to WHO, disaster is a sudden ecological phenomenon of sufficient magnitude to require external assistance. While according to American college of Emergency Physicians disaster is a destructive effect of natural or manmade force overwhelm the ability of given area or community to meet the demand for health care.
Disaster management plan is very important since it can reduce the impact and damage to the society. We can not control the the disaster itself, but at least by making a good prevention, mitigation and preparedness can reduce the damage that will occur.
Mitigation - any activity that reduces either the chance of a hazard taking place or a hazard turning into disaster.
Prevention - avoiding and reduce the chances of disaster, usually the impact and damage of disaster.
Preparedness - plans or preparations made to save lives or property, and help the response and rescue service operations. This phase covers implementation/operation, early warning systems and capacity building so the population will react appropriately when an early warning is issued.
Response - includes actions taken to save lives and prevent property damage, and to preserve the environment during emergencies or disasters. The response phase is the implementation of action plans.
Recovery - includes actions that assist a community to return to a sense of normally after a disaster.
