==Causes of hazards==
There are many causes of hazards, but they can broadly be termed in to:
*'''Natural''' - Natural hazards include anything which is caused by a natural process, and can include obvious hazards such as [[volcano]]es to smaller scale hazards such as loose rocks on a hillside and volcanoes.
*'''Man made''' - Hazards created by humans, which includes a huge array of possibilities, probably too many to list, as it includes long term (and sometimes disputed) effects such as [[global warming]] to immediate hazards such as building sites
*'''Activity related''' - Some hazards are created by the undertaking of a certain activity, and the cessation of the activity will negate the risk. This includes hazards such as flying.
