The Natural Disasters in Australia and Their Effects
Earthquakes are caused by the shifting of the Indian-Australian plate,
which is being pushed north and is colliding with the Eurasian,
Philippine and Pacific plates. The stress from this collision is
released during earthquakes. Earthquakes can occur anywhere in
Australia. Adelaide has the highest earthquake hazard of any capital
city, with more earthquakes in the past 50 years than any other.
Thunderstorms however are more common on the east coast of Australia.
Thunderstorms develop when dense cold air meets warm, moist air, which
is less dense. A trigger, such as solar heating can then begin the
development of a thunderstorm. Strong upward currents of air develop.
As the air is carried upwards quickly water droplets in the air
condense to form rain. These raindrops can turn into hail.
When these rain drops reach high levels they freeze, forming hail
stones. These hail stones then grow steadily in size as they are
carried up and down by strong currents of air. Hail ...
Hurricane Katrina was one of the most interesting and deadly hurricane to ever hit the United States. This hurricane devastated New Orleans and all of its inhabitants. This hurricane was especially devastating as New Orleans is 13 feet(3.9624 metres) below sea level. The government wasn’t prepared for the damage of New Orleans, and neither were the Levees. The Levee crash was one of the major causes of the flooding in New Orleans. The deaths and damages cost billions. After this storm many people didn’t want to move back to their home, New
Natural disaster can be traumatic events that have a huge impact on the mental health of communities often resulting in an increase in mental health needs that don’t get met. In 2005, one of the worst natural disasters in U.S. History, Hurricane Katrina, hit the states of Louisiana and Mississippi affecting 90,000 square miles. In addition to the 2000 people killed and million displaced as a result of the Hurricane, a significant number of people, according to multiple studies, suffered and continue to suffer from mental health issues including stress, anxiety, depression and PTSD. After the Hurricane, communities were both physically and emotionally devastated leaving individuals without loved ones, homes, belongings or jobs (Rhodes, J., Chan, C., Paxson, C., Rouse, C. E., Waters, M. and Fussell, E., 2010. p. 238). The Gulf Coast, whose mental health system had been obliterated by the Hurricane, was in desperation of mental health services in order to prevent chaos and initiate recovery immediately. The U.S. government did not provide sufficient services; thus, illustrating how the affected communities’ mental health needs weren’t being met and continue to not be met today. The survivors of Hurricane Katrina did not receive sufficient mental health services due to lack of government action and lack of programs with the capacity to assist large numbers of people which resulted in the individuals and communities affected to endure homelessness, poverty, and mental health issues even till this day.
On February 1, 2003, the Space Shuttle Columbia was lost due to structural failure in the left wing. On take-off, it was reported that a piece of foam insulation surrounding the shuttle fleet's 15-story external fuel tanks fell off of Columbia's tank and struck the shuttle's left wing. Extremely hot gas entered the front of Columbia's left wing just 16 seconds after the orbiter penetrated the hottest part of Earth's atmosphere on re-entry. The shuttle was equipped with hundreds of temperature sensors positioned at strategic locations. The salvaged flight recorded revealed that temperatures started to rise in the left wing leading edge a full minute before any trouble on the shuttle was noted. With a damaged left wing, Columbia started to drag left. The ships' flight control computers fought a losing battle trying to keep Columbia's nose pointed forward.
In Victoria Melbourne, on the 7th of February, 2009 the weather conditions were some of the worst ever recorded. Wind speeds reached above 100km per hour and temperatures reached 46 degrees Celsius, thus causing the biggest bushfire in Australia, known as, the Black Saturday Bushfires.
Climate change has the potential to devastate millions in Australia. Rising temperatures will impact the landscape of Australia by decreasing Australia's forests. Australia is going to have to spend billions of dollars to make sure their safety from climate change. The people in Australia will need to be strong and flexible to make it through this tough time they're going through, and Australia will have to find a way to fix this problem before it's too late. Climate change is something that will affect the entire world and it's not an issue to take lightly. Australia’s solutions are not simple at all and in order for them to work everyone will have to work together. Climate change in Australia will impact the environment, the economy, and the lives of Australians, an example of a solution is to cut down on carbon emissions.
My time at World Relief has come to a close or at least for now. After over two hundred hours spent with this organization over the course of an internship and volunteer hours I have gained a multitude of knowledge. I have been able to thoroughly compare and contrast the variations between World Relief and some of the other organizations I have worked for. World Relief opened my eyes to new possibilities, challenged me to learn new skills, and also made me more observant to conflicts as well.
August 23rd, 2005; Hurricane Katrina, formed over the Bahamas, hitting landfall in Florida. By the 29th, on its third landfall it hit and devastated the city of New Orleans, becoming the deadliest hurricane of the 2005 season and, one of the five worst hurricanes to hit land in the history of the United States. Taking a look at the years leading to Katrina, preventative actions, racial and class inequalities and government, all of this could have been prevented. As presented in the newspaper article, An Autopsy of Katrina: Four Storms, Not Just One , we must ask ourselves, are “natural” disasters really natural or, are they a product of the people, who failed to take the necessary actions that needed to be taken?
Fire at any level can be devastating, yet the effects that wildfires have on every worldwide country really has left its mark on the land. As written by world renowned wild fire spokesperson Smokey the Bear, “Every year, wildfires sweeps through parts of the United States setting wilderness and homes ablaze. On average these raging infernos destroy about four to five million acres of land a year. But in 2012, wildfire burned more than 9.3 million acres, an area about the size of Massachusetts and Connecticut combined” (U.S. Wildfires). Destroying homes, crops, towns and of course forests. Yet the effects of these fires can be seen from a negative perspective as well as some positive. Plus there are natural causes as well as manmade that makes these destructive fires erupt and become almost unstoppable in seconds.
Natural Disasters can occur anywhere at anytime. Some are more predictable than others, but they all bring hardship to everyone’s life. Examples of natural disasters are Earthquakes (Haiti 2010), Tornadoes, Tsunami, Hurricanes, Wild Fires, Winter Storms, Heat waves, Mudslides and Floods. Regardless of what kind of disaster occurs, bottom line, everyone needs to be prepared mentally and physically to deal with the aftermath. Education is the first step to prepare you to deal with any major disaster. Three of the major disasters that can potentially disrupt normal day to day operations in our lives, are Hurricanes, Tsunamis and Tornadoes.
Good morning everybody, by now all of you will have seen the morbid and shocking images on television. Known to man as one of the most damaging, disastrous and detrimental typhoons in history, Super Haiyan ravaged through our entire country leaving nothing to spare. Within a split second those which were known as our most prized possession were instantly consumed by the monstrous typhoon. Our initial reports show that this monstrosity left a wake of massive destruction that is unthinkable, unprecedented and horrendous. Thousands of neighbourhoods were left in ruins, thousands more were injured among those were children struggling with all their might to deny the horrible fact that their parents were lying on the ground, lifeless, cold, pale . The devastation is so staggering that I struggle to find words to describe the horrific events that have occurred.
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
A tropical cyclone is a warm-core, low-pressure system producing high winds that spiral counter-clockwise (in the northern hemisphere) and inward, with the highest winds near the center of circulation. The large counter-clockwise and inward flow is characteristic of the nearly symmetric structure of tropical cyclones as they are comprised of rain bands spiraling toward the center. These warm-core storms typically form over the tropical and subtropical oceans and extract their energy from the heat content of the oceans.
Hurricanes occur all over the world, at different times, but commonly through June first and late November. However in late August 2005 a catastrophic hurricane struck. This was Hurricane Katrina. With winds traveling over one hundred miles per hour making it a category five on the Saffir- Simpson Hurricane Scale it was said to have cause billions of dollars’ worth of damage. Hurricane Katrina flooded nearly forty thousand homes, and killed at least two thousand people (“Hurricane”). An average category five hurricane has enough energy to power street lamps for more than twenty seven thousand hours (Williams 58). Knowing about Hurricane Katrina, and the devastation of the city in New Orleans would be beneficial. Also, general information on hurricanes can help civilians and people of higher authority better understand and prepare for damage that could once hit their town and community. Because experts know the general information on these storms they can help explain to the public why and how Hurricane Katrina and other hurricanes occur. Hopefully, in the future civilians will know and use this information to their advantage against hurricanes.
Each part of Australia has its own unique combination of weather systems that produces severe bushfire conditions, but in all cases these conditions result from hot, dry winds blowing from Australia's central arid region.
The increase in unpredictable natural disasters events for a decade has led to put the disaster preparedness as a central issue in disaster management. Disaster preparedness reduces the risk of loss lives and injuries and increases a capacity for coping when hazard occurs. Considering the value of the preparatory behavior, governments, local, national and international institutions and non-government organizations made some efforts in promoting disaster preparedness. However, although a number of resources have been expended in an effort to promote behavioural preparedness, a common finding in research on natural disaster is that people fail to take preparation for such disaster events (Paton, 2005; Shaw 2004; Spittal, et.al, 2005; Tierney, 1993; Kenny, 2009; Kapucu, 2008; Coppola and Maloney, 2009). For example, the fact that nearly 91% of Americans live in a moderate to high risk of natural disasters, only 16% take a preparation for natural disaster (Ripley, 2006).
