What are Bushfires?


A bushfire is a fire usually caused by naturally effects and spread quickly throughout bushland, forest and tundras with dry tall grass. Sometimes they are started on purpose and that is illegal and cause major damage to houses and can take lives as well. Bushfires are dangerous and you should keep well away from them and also if you live in a bushfire danger zone you should have a plan of what to do when bushfires come.  Bushfires are known to cause major damage and can kill many people and wildlife. Bushfires happens when there is low rainfall or droughts, heatwaves, high temperatures, strong dry winds, low humidity and human activity. They also occur when there is an El-NiƱo causing drought in Australia. Bushfires are common in Australia since we have many eucalyptus trees that are high in oil and very dry. The hot sun and dry atmosphere encourages dried leaf to be ignited and then the flames would spread quickly. Bushfires will burn down anything in its way and can spread from one bushland to another quickly. Bushfires also burns down human made objects such as houses and farms causing billions of dollars in damage. Firestorms are intense fires that happen when there are bushfires and this causes spot fires long distances away. The fire front spread the quickest so be sure to be out of the way. Bushfires can be clearly seen from out of space the heat can be felt hundreds of kilometres away.

Smokes from the Victorian bushfires

The Victorian Bushfires (7-8 Feb 2009) (Black Saturday)


On 7 February 2009 as many as 400 fires were recorded across Victoria. Before the fire started heatwaves and extreme heat was felt all over Victoria. There were 78 communities affected, 173 lives lost and 2029 homes destroyed. Twelve major fires and many more minor fires burned over 450,000 hectares of land and affected at least 78 communities. The Victorian Bushfires Royal Commission was established on 16 February 2009 to investigate the causes of and responses to the bushfires with the final report released and published in July 2010. The Insurance Council of Australia estimated the 2009 damage at $1070 million. This major fire was nicked named ‘Black Saturday’ because the fire started early Saturday (07/02/2009). The fires that broke out on Black Saturday spread quickly and soon were out of control and so people had to evacuate and leave their properties. The fire brigade only can maintain the fire and could not stop it completely. The fire spread quickly because of the low rainfall in the months following the fires and the dried eucalyptus provided a good fuel for the fire to spread even quicker than it was expected to.

How do Bushfires affect you? (The effects of a bushfire)


Bushfires are one of many natural disasters that can have critical effects on human and animals. Bushfires are known to cause many damage and destroy what’s in its path. They will burn anything combustible and this will cause many man made structural to be damaged. A bushfire then can result in millions of dollars in damage and usually the recovery process is long and expensive. A bushfire can also isolate the community since that they all need time to recover from the fire. But a bushfire can also help communities get closer together and allow them to develop closer relationship. This allows communities to pick up from where they are and rebuild the community quickly. Bushfires also can damage the environment badly not just by burning down bushland but also bushfires releases a lot of carbon-dioxide into the atmosphere. Bushfires can also kill a lot of animals an especially the slow moving ones which can’t get away from the fire fast enough. But bushfires are a necessary in the natural environment as it is needed for some plants to grow. As some plant seeds only grow after a bushfire. This will kill of the old dead plants and give way to new plants to take their place.



Where can I get help?


A bushfire can be dangerous and is not something that you should tackle by yourself. Then where do you get help when a bushfire is coming?
Bushfires aid is provided by many government departments and they include, the NSW Fire Brigade, SES and NSW Rural Fire Services. All of these 3 services can help you during a bush fire.

They are a department that only fight fires within a distant but anything beyond that distant the Rural Fire services takes charge.

SES: The NSW State Emergency Service (SES) is an emergency and rescue service dedicated to assisting the community. It is made up almost entirely of volunteers, with 228 units located throughout New South Wales. While our major responsibilities are for flood and storm operations, the SES also provides the majority of general rescue effort in the rural parts of the state.

 
NSW Rural Fire Services: On 1 September 1997, The NSW Rural Fire Service (NSWRFS) was established by an act of Parliament as the successor to the first bush fire brigade, redefining the world's largest fire service and building on a century of experience in protecting some of the most fire-prone areas on earth. Today the Service comprises over 2,100 volunteer rural fire brigades with a total membership of just over 70,000.
