Recommended: Natural disaster impact on society
During the last years, there has been an increase in the reports of natural disasters. Natural disaster come in many forms such as earthquakes, tornados, floods, blizzards, hurricane fire, and volcanic eruptions and it can affect thousands of people in the world. Natural disaster can be foreseen with the aid of advance technology, but overall, nature’s wonders occur unexpectedly, and the majority of the people don’t know what to do or what to expect before, during or even after the disaster Firstly, the most direct and immediate impact of a natural disaster on a society is the loss of human life. Let start with the Mediterranean island of Stroggli was completely wiped out by a volcanic eruption in the 1500 B.C. in which the death of people …show more content…
Also the earthquake of 7.0 in Haiti in 2010, this lead to over 200,000 deaths, 2 million homeless, and 3 million people in need of emergency aid. Last the earthquake in Pakistan in 2005 that registered 7.6 in the Richter scale, causing the death of 75,000 people with 106,000 people injured this earthquake happen in Kashmir near the city of Muzaffarabad. What is an earthquake? “Is a shaking of the ground caused by the sudden breaking and movement of large sections (tectonic plates) of the earth 's rocky outermost crust.” (http://www.vtaide.com). Earthquake can happen at any time and at anywhere in the whole world. At this moment as I’m writing this essay 86 earthquake happen around the world and 50,586 in the past year according to http://earthquaketrack.com. An estimated of 200,000 people were killed in Syria due to an …show more content…
In 2005 the hurricane struck the Gulf Coast of the United States, it was a Category 3 rating on the Saffir-Simpson Hurricane Scale and it brought sustained winds of 100–140 miles per hour. This hurricane causes an estimate of more than $100 billion in damage, and hundreds of thousands of people in Louisiana, Mississippi and Alabama were displaced from their homes. Also the cyclone Nargis in 2008 it was evaluated as a category 3 or 4 hurricane on the Saffir-Simpson scale, and it hit the northern Indian Ocean, approximate 84,500 people were killed with 53,800 missing. This cyclone landed “in Myanmar and devastated the Ayeyarwady Delta region along with its 37 townships for two day.”
What is the most devastating natural disaster known? Hurricanes are one of the most catastrophic and natural events to ever be experienced. They can be up to 600 miles across and have wind speed of 75 to 200 mph. Hurricane Sandy and Hurricane Katrina happened to be two of the most devastating hurricanes in history.
Earthquakes happen about 20,000 times a year worldwide. They can destroy almost anything.In 2011, Japan had 9.1 magnitude earthquake, close to the highest magnitude of 9.2 in Alaska. They suffered tremendous damage from such a strong earthquake. The year before Haiti suffered from a 7.0 magnitude earthquake, still quite high compared to small tremors at magnitude 0-2. Japan recovered and rebuilt much faster than haiti did though. Haiti isn't even quite done recovering yet. The earthquakes had such different effects on the countries because of their economy, the condition of their people, and population rates.
This is one of the most commonly asked questions around the world. Earthquakes are very common because the Earth’s tectonic plates are constantly moving, because they are constantly moving earthquakes are happening quite often across the globe. Statistics show that over 1 million occur each year worldwide (see source 9), but earthquakes don’t have to be felt for them to have occurred. Statistics prove that 1 100 000 earthquakes happen per year worldwide that can’t be felt by humans. Statistics show that about 11 670 earthquakes occur that can be felt in the area of occurrence and sometimes even further
Early in the morning on August 29, 2005, Hurricane Katrina struck the Gulf Coast of the United States. When the storm made landfall, it had a Category 3 rating on the Saffir-Simpson Hurricane Scale–it brought sustained winds of 100–140 miles per hour–and stretched some 400 miles across. The storm itself did a great deal of damage, but its aftermath was catastrophic. Levee breaches led to massive flooding, and many people charged that the federal government was slow
D.J. Dowrick (”Earthquake Risk Reduction”in Wiley) explains that seismic hazard is any physical phenomenon associated with an earthquake that may produce adverse effects on human activities. Earthquakes occur very suddenly without any warning. Thus, earthquake not only destructs people’s living environment, but also affects people’s mental health. People are more scared of earthquake. In 2010, there are two severe earthquakes, which are Haiti Earthquake and Chile Earthquake. Both of these two earthquakes produced the various impact considerably across countries and regions. The purpose of this essay is to analyse those two earthquakes according to knowledge such as why they occur, how strong they are, and what the impact they made. Even though people still can not predict earthquake, through analyse earthquakes, they can prevent it bring huge losses.
Earthquakes are best described as a shaking or vibration of the ground caused by breaking of rock. Sometimes they are very strong and other times you would hardly notice them. This shaking occurs when stress that builds up in the crust is suddenly released as the crust breaks free and/or slides against the other pieces of crust. Earthquakes may also be thought of as the breaking of a popsicle stick by applying pressure to both ends at the same time. Should you try this experiment , you will feel the pressure build up as you apply more force until the stick snaps. When the stick snaps you will feel an instant of pain at your fingers as the stress reduces and energy waves move throughout the stick. When the earth's crust is placed under similar types of stress, binding as the stress builds, it will also snap and release the energy into the surrounding rocks, 'ooch'. Thinking about earthquakes will become more clear if you try another experiment.
On August 29th, 2006 New Orleanians were expecting a total of 12 to 15 inches of rain and extended five or six inches from the upcoming storm later known as the costliest hurricane in U.S history. The Category 3 hurricane devastated most of eastern North America with blustery winds of 170 mph (280 km per hour) and storm surge values ranging from 10 to 20 feet. The storm called ‘’Hurricane Katrina’’ originated in the Bahamas on August 23th, 2005, but only became a devastation the next day. On August 28th, Hurricane Katrina succeeded a Category 3 hurricane(sustained winds of 122 kt) and exceeded the limits of a Category 5 storm (sustained winds of 136 kt). The following day, the cyclone shifted northwest towards Mississippi and Louisiana, where the hurricane hit the hardest. New Orleans was one of the cities where the most damage was caused; leaving a negative environment, residential and economic effects on the Gulf Coast.
Natural disasters affect the lives of people in torturous ways. It almost always costs the lives of innocent bystanders. Costs of the cleanup can be in the billions of dollars. It is disturbing to realize the damage and destruction that nature is capable of releasing on humans at any moment. Both the eruption of Mount St. Helens and The Great Mississippi River Flood are different in many ways, but the same in that they both affected people negatively.
The dangerousness of earthquakes are rated from one to ten. One being you aren’t able to feel it and ten being VERY powerful. There was a deadly earthquake, almost no one survived. A deadly 7.2 earthquake occurred in the Central Philippines. All signs and clues pointed to the East Bohol Fault. A 6 rated earthquake that happened before, injured 300 people and caused a tsunami. But the 7.2 earthquake didn’t cause any tsunami. All of the dangerous earthquakes damaged ports, schools and airports; even a hospital collapsed killing at least 18 people. Children were injured in stampedes at two sports complexes while others rushed to the exits. Five people were killed in a earthquake - triggered landslide. People respond to a natural disaster by gathering resources, spreading the word, and government help.
Earthquakes can be very dangerous but what matters the most is that everybody is safe, and that we need to work together. One earthquake, in the Philippines, was truly devastating. It was classified as a 7.2 magnitude. The Philippines responded very well by gathering their resources, spreading the word, and giving donations. They bounced back very quickly.
A little over ten years ago, a catastrophic event struck the American shoreline and left devastating effects for years to come. It was very early in the morning on August 29, 2005; Hurricane Katrina struck the Gulf Coast of the United States. For days before, the hurricane could be charted by various meteorologists so there was no mystery that a very large storm was approaching a very vulnerable part of the United States coast line. The storm made landfall as a Category 3, meaning sustained winds of 100–140 miles per hour. The hurricane stretched some 400 miles across. While the storm hit relatively quickly and harshly, its aftermath was the most catastrophic. Levee breaches led to massive flooding.
The effects caused by earthquakes are devastating. They cause loss of human life and have effects on infrastructure and economy. Earthquakes can happen at any time anywhere. In January 12, 2010 an earthquake of a magnitude of 7.0 hit the nation of Haiti. An estimation of 316,000 people were killed, and more than 1.3 million Haitians were left homeless (Earthquake Information for 2010). Haiti was in a terrified chaos. After the earthquake, families were separated because many of the members were killed. Homes, schools, and hospitals were demolished. People lost their most valuable belongings. It will take time for the country to recover from this terrible disaster. The long damages are economic issues, health-state, and environmental issues that effect in the beautiful island of Haiti.
Hurricanes are powerful and destructive storms that involve great rain and wind. The United States of America has dealt with many hurricanes that have cost a great amount of damage. However, there is one hurricane that happened in 2005 that stands out among the others, Hurricane Katrina. Hurricane Katrina was one of the worst hurricanes to hit the United States, a category 5 on the Saffir/Simpson Hurricane Scale. An estimated 1836 people died because of the hurricane and the floodings that happened after (Zimmermann 1). Katrina initially beg...
Earthquake is the earth tremor that results from the sudden release of the pent-up energy in the earth’s crust. This released energy creates the seismic waves that determine the frequency, type and size of the earthquakes. Any earthquakes whose magnitude is bellow 5 on the Richter scale is considered weak, while the earthquakes whose magnitude is above 7on the Richter scale is considered potentially dangerous. The largest earthquake ever register in the history of man is the earthquake in Japan in 2011 which had a magnitude of 9.0 on the Mercalli scale(Seeram, pars. 4-5). While most earthquakes are causes by seismic events on the earth’s crust, these can be accelerated by natural events, or the activities of the human beings. For example, when the geological faults lines rapture, pressure is created in the earth’s crust forcing its way out thereby causing a break or sliding along the fault line. Volcanic activities are also known to cause earthquakes and so are nuclear test, bombs and landslides. The hypocenter is the initial point from which the raptures occur, while the epicenters is the ground directly above the hypocenter (Zacharias,, sec. A)
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.
