Transcript of Natural Disasters
Jerry Coffey, October 14, 2010 Tornadoes are usually the result of a super cell thunderstorm. When wind direction changes, cold air goes down while warm air rises and begins to spiral down, a funnel cloud is formed, known as the tornado. Some of the most violent tornadoes can have wind speeds of more than 250 mph, leaving a damage path a mile wide and 50 miles long. When the 7.0 magnitude earthquake hit Haiti in 2010 the estimated cost of the rebuilding process is 14 billion dollars The Haiti earthquake caused 230,000 deaths with hundreds of people still left injured The destruction done when an earthquake hits can be minimal or very extensive. When a tsunami hit the coast of Japan in 2011
the cost to help rebuild the city is an estimated
235 billion dollars. The Japanese tsunami/quake caused 15000 deaths so far and thousand more are injured and missing. Tsunamis have the ability to carry wipe out villages, cities and small towns and make them look like they never existed in the first place. http://abcnews.go.com/Business/HurricaneKatrina/story?id=2348619&page=1 Charles Herman 2006 http://curiosity.discovery.com/question/how-does-a-hurricane-form 2011 http://environment.nationalgeographic.com/environment/natural-disasters/earthquake-profile/ 2012 www.youtube.com Destroyed in Seconds

Brian Handwerk, September 6, 2005 Hurricane Katrina has been considered one of the most deadly hurricanes in USA history, over 1,800 people were killed. Hurricane Katrina tore though the Southern United States in 2005, leaving houses in pieces, trees uprooted, lives lost, and communities unlivable and abandoned. Damage was caused over 100 miles (160 kilometers) from the storm's center. In the after math of Hurricane Katrina, hundreds of thousands of local residents were left unemployed. The total economic impacts in Louisiana and Mississippi alone, may have been about $150 billion. Fast Facts At its peak, Hurricane Katrina was classified as a category five storm. With that, the wind speeds were up to 175 miles per hour (280 kilometers per hour). Many refugees were living below the poverty line before Hurricane Katrina hit. Hurricanes are becoming more disastrous because of human activity. With cities building up and people moving closer to the world's coastlines, where hurricanes are more likely to occur, storms are going to be more destructive because the coastlines are so heavily populated. Now that forecasting and emergency response have improved, they have lowered hurricane casualty rates. Hurricanes and typhoons are generic terms for tropical cyclones, they are tropical or sub-tropical ocean storms with winds over 74 miles an hour (65 kilometers an hour). http://www.cnn.com/SPECIALS/2005/katrina/interactive/timeline.katrina.large/frameset.exclude.html Roughly 10,000 people had to take refuge in the Louisiana Superdome. Hurricane Katrina caused damage that affected migratory birds, coastal marsh vegetation, coastal floodplain forests, mangrove forests, estuaries, and the endangered manatee specifically in Pearl River, MS. http://pubs.usgs.gov/circ/1306/pdf/c1306_ch6_a.pdf
Stephen Faulkner, Wylie Barrow, Brady Couvillion, William Conner, Lori Randall, and Michael Baldwin Animals that had the ability to burrow underground and hide under thick cover could deal with this catastrophic event much easier than those that lived in trees and in the open. http://www.wisegeek.com/what-was-hurricane-katrina.htm The total cost of the damage caused by Hurricane Katrina was between $96-$125 billion, with $40-$66 billion in insured losses. Roughly 300,000 homes had been destroyed or made uninhabitable. The total economic loss from Hurricane Katrina was estimated to be $250 billion, taking into consideration gas production and economic growth were negatively affected. http://useconomy.about.com/od/grossdomesticproduct/f/katrina_damage.htm
Kimberly Amadeo Hurricane Katrina took one of the worst possible paths imaginable for the people of the southern USA. Some of the main money making industries were damaged, this includes the casinos in Mississippi, and the chemical plants and sugar crops in Louisiana. http://useconomy.about.com/od/criticalssues/a/Tornado-Damage.htm
Kimberly Amadeo, June 18, 2012 The outbreak in 2011 caused $5 billion in damage. Since 2008, the average of 800 tornadoes a year has increased to more than 1,300 a year. That year the total number of tornadoes was 881. The tornado outbreak killed 327 people, this was the third-deadliest single outbreak in U.S. history. The Largest Tornado Outbreak in U.S. history: April 25-27, 2011 In April 2011 there were 600 tornadoes that formed, although May is usually the worst month for tornadoes, April 2011 was the most active month for tornadoes on record. At least two of the storms were EF-5 twisters, producing wind gusts of more than 200 miles per hour. With wind speeds that wild, trees get uprooted or just snap, animals can get picked up and thrown miles from their homes, if a tornado goes through or near any forest or stream it destroys the habitat for the animals that live there and ones that feed off of the surrounding vegetation. Researchers believe that tornadoes are occurring more often now because of Global Climate Change. They say that with the changing climate it is causing strong updrafts, where the wind moves up and down, creating conditions that are more likely to cause tornadoes. The cost of a tornado outbreak, referring to the economy or the physical damage, depends on if it hits an urban or a rural area. Villages were wiped out leaving 500,000 citizens homeless, and some were carried by the waves away from the village. The city has been destroyed and it is estimated that it will take 5 years to repair the damage. When the Japanese quake/tsunami hit the debris was carried all the way over to British Columbia and now the province has to pay to clean up the debris and now there is a growing concern that there may be invasive species coming with it. Since tsunamis are waves from the ocean they can carry the debris out into the sea which causes habitat destruction for the sea and the species in it. The same is true that tsunamis can carry species onto land which does not help. Other countries have to also pay because tsunamis do carry debris through the waters so once they hit land those countries have to pay for the cleanup. For instance when the earthquake hit Haiti it collapsed buildings of all sizes, homes and open land is destroyed. The poverty level is through the roof and thousands of people are still left homeless, hungry, and trying to seek medical attention. Natural disasters are bad and can happen any time of the year even if it isn't their predicted seasons. Each year thousands of people are affected by these powerful storms and the cost to fix the damage can going into the billions of dollars. It can take seconds for a storm to wipe out a town but it will take years to replace and repair the damage. Earthquakes can also impact the species in the area because of the power it can cause forestry to collapse which is a food source, and shelter for the species and many species can also die because of the collapsing of their homes and lack of food. Tsunamis are terrible for the species sound the water because they wipe away everything so the species habitats are destroyed, food is destroyed, and the species themselves can be washed away to a different ecosystem and then they will not survive. Plants also suffer because they are drenched by the water but there is no sunlight so they cannot perform photosynthesis.
