IN CONCLUSION.
Sunday, April 11, 2010

Bushfires are on of the natural disasters, and occur in Australia more than any other country, have a huge impact on the environment, the economy, and to the people who witnessed it, and to the victims as well. They need certain circumstances to happen, and, depending on actions taken, their danger can be increased or decreased. Remember, when there is a bushfire, call 000 straight away, and ask for the fire department. Bushfires also cause a response from society, and can have a long lasting effect mentally on victims. Bushfires often destroy hundreds of homes, and many towns.


RESPONSES OF SOCIETY.

Bushfires cause responses from the society, and victims themselves. Society will experience many different feelings during a bushfire, and after a bushfire.

Some of these feelings are:

Determination;
Society will be determined to help the bushfire victims as much as they can, because they see the pain they have suffered, and empathise with them.

Fear;
After the bushfire, they might feel scared and anxious because something like this could happen again, and more damage could be done. During the bushfire, they could be afraid because they know they might lose their friends, loved ones, and members of the community, or that they would end up badly injured.

Indecision;
During the bushfire, victims often don't know what items they should save, how much time they have left before the fire destroys everything, and sometimes don't know whether they have enough time to get everything they want to save and make it out alive.

Longing;
For the things that are gone, and for things that will never be able to happen because of the bushfire.

Numbness;
The victims can't understand their feelings.

Regret;
For not being able to do things which could have reduced damage, and for not making the most of life in that area which was destroyed.

Sadness;
Knowing that loved ones, friends, and fellow community members have suffered terribly, and are dead or injured.

Shame and guilt;
For not being able to save people or reduce damage, for being alive and not in physical pain, and for being better off than others.

Shock and disbelief;
They never expected something like this to happen, and feel as if what they had is all gone.

Strength;
For being able to help others, knowing that they have been good enough to change someone's life (This is after they have helped the victims.)

Children, victims, will feel vulnerable, and will act like how they were when they were little, as in, have a lot of nightmares, become clingy or distressed, and cry a lot. Children who have witnessed the event on television, will react in a similar way,

Society and communities, (sometimes throughout the country depending on how much damage was done) try their best to raise money for the victims, because they have lost many of their needs. They empathise with them, which raise the hopes and lift the spirits of the bushfire victims. Australian Red Cross, is one of the popular organisations which fundraise.

Hungry Jacks raised the amount below for the Victorial Black Saturday Bushfire Appeal.

The amount above was donated to the Tooday Bushfire Appeal.


Victims appreciate what society has done for them, and are very grateful for all the help received, and feel stronger, and high hopes, knowing that, out there, there are many people who know what they have been through, and are trying to help them.

The media realeases many videos of the bushfire, its damage, and about people's responses and feelings, and it becomes news.


IMPACTS OF THE NATURAL HAZARD ON THE ENVIRONMENT, ECONOMY, AND PEOPLE.
Saturday, April 10, 2010




Bushfires have a strong impact on the environment, economy, and the people.

The impact on the environment:
The number of plants and bushes are drastically reduced. Trees are burnt down, which means oxygen is also annihilated by bushfires, and this leads to damage to the ozone layer. Bushfires leave animals dead, or without homes. In addition to that, many peoples' houses get burnt down. There are some positive outcomes of bushfires, for example, regrowth of plants. In fact, bushfires are an essential part of the life cycle of some Eucalyptus species. Bushfires also stimulate growth of many grassland plants. They can also harm livestock, therefore leading to less food for humans, and less money for farmers.

The impact on the economy:
A lot of money was used after bushfires destroyed many peoples' homes and buildings. There was an estimated cost of $200, 000, 000 to repair the damage caused by the Ash Wednesday Bushfires in 1983. Insurance losses are high as well, one cost being around $500, 000, 000. The Black Saturday bushfires costs were rather expensive. $1000 was offered to the victims the day after the bushfires happened.

The impact on the people:
When a bushfire occurs, the majority of people whose home was near the place where everything got burnt, become homeless. Depending on the bushfire's level of damage, sometimes they have to move houses. Take for example the Victorian Black Saturday bushfires in February, 2009, there were 2000 homes desroyed. Some poeple have to start their life all over again, because in some cases, the complete town is destroyed, including where they work, where their kids went to school, which means they have to go to a new town, because the damage done to the place they used to live in was too extreme too repair. In many cases, people suffer high levels of distress and grief, and shock, because everything they had was gone, in just a few hours. Victims will be scared, and will probably be depressed for the next few weeks, sometimes even months. Children will be scared, and in distress. They will feel vulnerable, and feel like anything could attack them, any moment, and feel helpless. Victims will also feel vulnerable, and very weak, and will rely on the society for help.

Bushfires overall have a negative impact, although they can bring victims closer, and encourage regrowth of some Eucalyptus species.


MAPS DESCRIBING AREAS IN AUSTRALIA MOST SERIOUSLY AFFECTED.
Friday, April 9, 2010

Australia has been affected by bushfires in many places, and here are a couple of maps to describe and demonstrate where.


Using the map above, you can see which climates bushfires occur in. Look at the bushfire areas on the maps below, use the above map to see what type of areas bushfires commonly occur in.


It can be concluded that the majority of bushfires occur in the dry parts of Australia.


GEOGRAPHICAL PROCESSES RESPONSIBLE FOR THIS NATURAL DISASTER.
Thursday, April 8, 2010

So what is a geographical process?
A geographical process is a process which changes the geography of a certain region.

A bushfire will need these components to occur:
Heat (high air temperature,) dry air (low humidity,) oxygen (wind,) fuel (vegetation.)

HEAT:
A chance of bushfire is when the temperature is over thirty-seven degrees Celsius. There is a very small chance of bushfires when air temperature is less than twenty degrees Celsius.

DRY AIR:
Relative humidity, (RH,) is the amount of dampness in the air. Low RH is the most dangerous, and can seriously affect the occurrance of bushfires.

OXYGEN:
Bushfires are highly probable when wind speeds are higher than 50 kilometres per hour. They push flames in all directions, dry out vegetation (which makes bushfires travel faster,) bends flames, blows burning objects and rubbish onto unburnt areas (thus spreading the fire,) and supplies oxygen to increase bushfires.

FUEL:
A fire can only burn if there is vegetation. The denser the vegetation, the more dangerous the bushfire will be. Double the amount of fine fuel will double the height of the flames, as well as its speed, and this quadruples intensity. Different types of vegetation will affect the bushfires at different levels. Vegetaion lets the fire flow more easily, and smoothly.

Some geographical processes which affect bushfires are slopes and human input.
Slopes inclining upwards make the fire's speed higher, in fact a bushfires speed doubles every 10% increase in slope, whereas, going downhill noticeably slows down a bushfire. As a flame goes slowly down a slope, its height increases four times when it reaches flat land, and when fire travels up an opposite slope, their height quadruples yet again. Droughts can also help trigger bushfires, because they already have high air temperature and dry air. Human geographical processes can be: cultured gardens, complex shaped buildings. These send the bushfires coming back, although some building features can slow danger of bushfires down, as well as its manageability.
