Wildfires 3
Wildfires 3 : In certain cases, wildfires can be sparked by natural causes, such as the sun's heat. It is cases like these that naturally fall into the 'natural hazards' category, as opposed to those wildfires that are set by arsonists. Either way, vegetation that has been exposed to lengthy drought spells provides the perfect conditions for the rapid spread of a wildfire. The threat of an out-of-control wildfire is, of course, the widespread destruction of vegetation, property and the potential loss of life, but the greatest obstacle in controlling such a blaze is the speed at which it can spread. Australia's state of New South Wales has a long history of devastating wildfires: the "Black Christmas fires" of December 2001 and January 2002 destroyed more than 5 000 km2 of land and 150 homes (although no-one was killed). More than 80 individual fires tore through the state for eleven days, and it required more than 20 000 people in fire-fighting capacities to finally put the last embers out
