Natural and Manmade Hazards (Disaster Management)

Natural hazards
These are the hazards which are caused because of natural phenomena (hazards with meteorological, geological or even biological origin).
Example: cyclones, tsunamis, earth-quake and volcanic eruption which are exclusively of natural origin.
Landslides, floods, drought, fires are socio-natural hazards since they caused by both natural and manmade.
For example flooding may be caused because of heavy rains, landslide, blocking of drains with human waste.

Manmade hazards
These are hazards caused due to human negligence.
Manmade hazards are associated with industries or energy generation facilities and include explosions, leakage of toxic waste, pollution, dam failure, wars or civil strife etc.
