A natural hazard is a natural process and event that is a potential threat to human life and property. The process and events themselves are not a hazard but become so because of human use of the land. A disaster is a hazardous event that occurs over a limited time span within a defined area. Criteria for a natural disaster are (1) 10 or more people are killed, (2) 100 or more people are affected, (3) a state of emergency is declared, and (4) international assistance is requested. If any one of these applies, an event is considered a natural disaster. A catastrophe is a massive disaster that requires a significant expenditure of money and a long time (often years) for recovery to take place.
