1 Wildfires can be caused by an accumulation of dead matter (leaves, twigs, and trees) that can create enough heat in some instances to spontaneously combust and ignite the surrounding area.  Lightning strikes the earth over 100,000 times a day. 10 to 20% of these lightning strikes can cause fire.
The causes of wildfires can be divided into 2 categories-natural and human. WIldfires are not like the other hazards that we have studied because, unlike earthquakes/volcanoes/storms, people can cause wildfires.Experts have suggested that 90% of wildfires are actually caused by people.ildfires are unplanned, unwanted wild land fires, including unauthorised human-induced fires.
