Disaster area

A disaster area is a region or a locale heavily damaged by either natural hazards, such as tornadoes, hurricanes, tsunamis, floods, earthquakes, technological hazards including nuclear and radiation accidents, or sociological hazards like riots, terrorism or war. The population living there often experiences a loss of energy supply, food, services, and an increasing risk of disease. Declarations of disaster areas open up the affected areas for national or international aid.
