Coastal Erosion

As far as coastal hazards go Australia only faces a single major problem. That issue is coastal erosion. Coastal erosion is due to a high volume of repeated wave action hitting land. As this process occurs the coastal line degrades and slowly begins to fall apart. Coastal erosion causes damage and can completely destroy human infrastructure. Because of this, this is more of an economic issue than a physical safety one. Though this hazard can and has displaced hundreds of people from their homes for the fear of the land eroding from under them. The erosion usually takes place on beaches and dunes, land that isn't dense and compacted. Unfortunately 50% of  Australia's coastline is made up either sand or dunes. These sediments can easily be displaced and washed away giving way to erosion. Not much can be done about a process so natural and that's always occurring. Though some use of seawalls are made to prevent erosion, little is done to prevent it. The government agency Geo- Science Australia does collect data and conducts research about coastal erosion. They give the data to the government and other public agency's that will make use of it. They support programs that helps protect and restore the coastline as well as research and implement new methods of preparedness for coastal erosion.

    great research! My country also has had the problem with coastal erosion because of the
    Nazca plate. Most of it comes from when there are tsunamis. Argentina has had tropical cyclones which cause it to have coastal erosion. Can't wait to learn more about your country.

Final Hazard Report

     Currently the biggest threat that stands to the countryside of Australia, it's beautiful land and people are bushfires. A bushfire is when a fire breaks out in an area where the vegetation is uncontrolled. This means no structures or infrastructure is being burnt down. They consist of dried grass, shrubs and the open wilderness. Australia is prone to bushfires for two main reasons.Many of the native plants have a high content of oil which makes them easier to ignite and they also burn for longer periods of time at a hotter temperature. Secondly is the dry hot climate, which are perfect conditions for natural bushfires to occur. Plants become more flammable at a low humidity because they release their moisture more easily. So this sets up the perfect storm for large scale bushfires to occur. They are a number one natural hazard priority because they are the biggest cause of natural disaster related deaths in the country. Secondly bushfires cause the 2nd most dam...

Hazards, Disasters, and Catastrophes

     Chapter one posed a multitude of information regarding the differences between natural hazards, disasters and catastrophes. Natural hazards are simply natural processes that take place on the Earth. Some natural hazards include volcanoes, earthquakes, and windstorms. These natural events pose only a potential threat in the case of human life or property being present in their wake. A natural disaster is an event in which less than ten people are killed, less than one hundred people are effected, a state of emergency is declared or a request for international assistance is sent out. Only one of these pieces of criteria need to be met for the event to be considered a disaster. Lastly a catastrophe is a major disaster that devastates an area. A large sum on money and extended period of time is needed to recover from these types of events.
