Define and classify different types of natural hazard (climatic, tectonic).

Hazard: an event resulting from environmental processes that threatens or actually causes damage and destruction to people their property and settlements.

Natural disaster: when a hazard causes serious damage and destruction.

If there were no people, there would be no hazards because hazards, in this context, means hazards to people

Geological	Climatic	Biological	Technological
Earthquakes	Storms	Fires	Nuclear explosion
Volcanic eruptions	Floods	Pests	Accidents
Landslides	Drought	Diseases	Pollution

Some hazards have human causes or are made more hazardous by human activity         

•  e.g Diseases- some diseases can be caused and spread by humans due to us polluting our environment. This results in dirty water and causes waterborne diseases such as cholera.

Hazards can sometimes combine to create events                                                                           

• e.g lava from a volcanic eruption can block a river which causes a flood or tsunamis associated with earthquakes
