What is a Hazard? Hazard is danger event, natural or human induced that could cause injury, loss of life damage to property, livelihood or environment. A hazard should be natural like earthquake, tsunami, volcanic eruption etc. Some of the hazards like floods landslides, droughts are socio -natural hazards since their cause are both natural and human induced. For example flooding in an area can take place because of excessive rain which is natural phenomenon or because of lack of proper drainage facility which is because of human negligence. Some of the hazards are human induced. Example of some human induced hazards are industrial accidents, rails, road and air accident, terrorist attack, dam failures, leakage of toxic waste, war and civil strife etc. A community may prone to multiple hazards for example; Gujarat is a prone of earthquake, but it is also frequently affected by floods and cyclone.
