How do bushfires start in Australia? There are many causes of bushfires, some resulting from natural events and others caused by human activities. In Australia alone we have more bushfires than anywhere else in the world. Humans have used fire for warmth and preparation of food for as long as we know. At some point, humans began using fire to hunt more. By burning the fields we could turn them into grasslands, which would make hunting much easier, but we probably soon discovered that fire cannot be controlled by man. Deliberately lit bushfires have a unique pattern, a clear pattern in terms of when and where the bushfire occurred. . When trying to understand deliberately small brush fires, firefighters and investigators must observe the time and location of the fire. They also need to take into account how different types of fires vary by area. Another aspect of understanding a deliberately set fire is to focus on the interaction between biological factors. All this information is used to develop strategies to prevent and target suspects in particular situations. Intentionally set fires usually start between 3 p.m. and 6 p.m., after school hours. The largest percentage of these deliberately set fires came from children 18 and under. Between 6 p.m. and 6 a.m. on weekends, 48% of all fires are started deliberately, compared to only 30% non-deliberately in the same time frame. Accidental starting of a bushfire includes topics such as: Leaving a fire unattended, Having an open fire on a dry, windy day, Glass from a bottle or mirror can cause the fire to turn a small flame in a raging forest fire, A cigarette or match that has not been extinguished or flammable chemicals left in it. areas or in the sun, middle of paper ......r into small pieces, as the small pieces land on dry fuel, this causes smaller fires. Climate change can cause and increase the risk of bushfires by causing hot and dry weather, thereby fueling bushfires. All of these natural bushfires can be dangerous, but they play an important role in the reproduction of some of Australia's native flora. An example of significant bushfires caused by human and natural activities would be Black Saturday. In February 2009, a major bushfire ravaged Victoria, killing 173 people and injuring 414 others. It holds the title of bushfire having caused the most loss of life in Australia. Up to 400 isolated fires were recorded that day. The main causes of the Black Saturday ignition were downed power lines, arson and lightning. As stated in the first paragraph; Fire cannot be controlled by man.
