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.
One reason Haiti and Japan had such different effects after the earthquakes is because of the difference in their economy. Haiti's
economy is definitely not amazing, especially compared to Japan's. Their average income per person per year is 1,300 dollars, compared to Japan's 35,500 dollars. Haiti's unemployment rate is 10 times more than Japan's. Haiti's population has 80% below poverty which is a ton of people! Haiti's budget is trillions under Japan’s and their importation value is loads lower. Haiti's debt is lower but that is because they spent less money in the first place. That is only parts of Japan superior economy. The worse the economy, the less money to rebuild after disasters. Also if you don't trade you might not be able to trade for resources in a disaster. Another reason the effects on the earthquakes were so severely different is because of the condition of the people. The life expectancy is much lower than Japan's in Haiti. That must mean life is not as healthy in Haiti. That could be because There are many less physicians and hospitals in Haiti. Japan's literacy rate is 99%, but Haiti's is only 52.9%. Reading the news and signs could be very important in a disaster, so you know the disaster plan. A last reason for the difference in the earthquake recovery was population rates. In japan there are few deaths and and average life expectancy is 84 years. There is a large amount of middle aged people. In Haiti, you are only expected to live up to 62 and there are lots of deaths. The population on Haiti is much lower than Japan's. The less people you have, the less to clean up after in a disaster. But then less people to sponsor and assist clean up. Some people may think the reason for the difference is because of exposure. They may say that haiti has a ton of disasters, especially earthquakes, so they weren't recovered from the last earthquake yet. Burt they may be surprised to know that Japan has a very high exposure rates as well. Actually Japan had a higher magnitude earthquake, and still recovered faster! Haiti has a very poor economy, bad condition of people, and bad population rates. That is the reason for the severe difference of the 2011 japan earthquake, and Haiti's 2010 earthquake. All of those things contribute to earthquake readiness and earthquake reaction. Its no wonder Haiti has not finished rebuilding!
The Haiti earthquake that occurred on January 12, 2010 just fifteen miles south of the Haitian capital of Port-au-Prince was a severely large-scale earthquake, at a magnitude of 7.0. The initial shock was then followed by a series of aftershocks with magnitudes ranging up to 5.9. Over three hundred thousand people died due to this extreme chaos. Many buildings collapsed and disintegrated under the force of the quake; both the cathedral and National Palace in Port-au-Prince were heavily damaged. In the aftermath of this tragedy, efforts to aid the people of Haiti with medical assistance, water, and food were hampered by the loss of communication lines as well as by roads blocked by debris. Over one million people were left homeless due to this quake. Two days after the earthquake, journalist Leonard Pitts wrote “Sometimes the Earth is Cruel,” an article describing how the people of Haiti responded to the disaster. In “Sometimes the Earth is Cruel,” a major theme is that some things are inevitable.
In 1910 a series of fifty-two earthquakes struck Arizona between September 10th-23rd and it caused much of the Flagstaff residents to flee the area as even strong households cracked and chimneys crumbled. The fifty-two earthquakes were all light-shock earthquakes with magnitudes between 4.0-4.2 that came right after another. If only one earthquake occurred in that timespan then it is likely that only objects would be knocked from shelves but no damage would be done to infrastructure, but the earthquakes happened right after another causing significant slight
The 1906 San Francisco Earthquake hit the Northern California coastline. The San Andreas fault shook 296 miles of the coast causing major damage throughout San Francisco, destroying about 80% of the city. Fires broke out throughout the city that lasted for several days. This was one of the worst Earthquakes recorded in history, killing 3,000 people.("The Great 1906 San Francisco Earthquake")
The Haitian government’s lack of preparedness for earthquakes despite the fact that earthquakes are common to the region is indicative of the governments inability and lack of resources to properly plan and protect it’s population against natural disasters. This lack of preparedness is not an isolated incident. Prior to the disaster, the World Bank and others were working with the Haitian government to incorporate disaster risk management into Haiti’s development strategy and to develop its capacity for disaster response. This capacity building was in its early stages of development when the earthquake hit, on January 12, 2010, and was mainly focused on hurricanes, which are the most common cause of natural disaster on the island (Margesson, 2010, p. 4).
At 5:12 a.m. on April 18th, 1906, the California city of San Francisco was awoken by a 7.8 magnitude earthquake. Chaos erupted with the earthquake leading to fire break outs throughout San Francisco (Cameron and Gordon. Pgs 69-73).The earthquake and the resulting fires caused destruction to majority of the city with buildings crumbling and igniting into flames. Many people died along with thousands and thousands of people being left homeless. This devastating earthquake left the city and United States in a financial crisis. Although the 1906 earthquake was one of the worst natural disasters in U.S. history, the city of San Francisco was able to overcome these substantial physical, social and economic impacts it had.
Haiti as a rich history, filled with many peoples’ blood and countless hopes of freedom. With such a rich history, the country has yet to become financially stable because of their past. From the beginning of the French settlement where slaves were brought over from Africa to harvest crops, to the dictatorship of the Duvalier family. Haiti has yet to see a time when they are not in need of help. After the racial caste systems were set in place, many people would not see a truly independent country. When France finally gave independence to Haiti, they did it for a price. After they paid that price, the US occupied them because of their location and many resources. Every year in Haiti’s history as a nation and before has effects on the world today. These effects are not hidden in fine print, but blatantly found within Haiti and those who have been involved with Haiti.
The economics of Haiti has deceased in the last 4 years after the devastating earthquake that struck it 4 years ago. The Haiti economy has become very poor and one of the poorest country in the south, Central America and Caribbean region making it ranked 24 out of 29 countries in this area and its overall score is below average. Haiti’s economic freedom is 48.1 making it economy the 151st freest country while in the last several years Declines in the management of government spending, freedom from corruption, and labor freedom make its overall score 2.6 points lower than last year. Recovering from the disastrous earthquake in 2010 with the support of the U.S. recovering efforts “Haiti’s post-earthquake reconstruction efforts continue, assisted by substantial aid from the international community. Governing institutions remain weak and inefficient, and overall progress has not been substantial. The parliament has not renewed the mandate of the Interim Haiti Recovery Commission, which had been tasked with overseeing reconstruction efforts but was unpopular.”( .heritage.org). The open market of Haiti trade weighted to be 2.1 this is because the lack of tariffs hamper the trade freedom of Haiti. Foreign investors are given national treatment but the investment is small and the financial sector is remained underdeveloped and does not provide any adequate support.
Currently, almost two years ago Haiti was struck by a 7.0 magnitude earthquake. It sparked an international urge to help aid and relieve Haiti of its catastrophe. Not only governments in various countries reached out, but independent organizations as well. This disastrous event showed how the world could come together when their neighbor is in need. But prior to this 2010 earthquake, Haiti was already facing devastation other than a natural one - societal.
In 2010 a 7.0 earthquake devastated Haiti. The earthquake left hundreds of thousands of people stranded without homes. It considered being the country’s worst earthquake in 200 years. It had destroyed so many buildings, homes, and office buildings. Haiti has always been a target for hurricanes and disasters of the ocean. Haiti is still trying to recover from all the devastations. Due to the earthquake, many Haitians live in run down homes. Four years later, some areas look the same after the earthquake hit the country.
On the 12th of January 2010, a quake 15 miles southwest of Port-au-Prince devastated the people of Haiti. The magnitude of the quake was 7.0 with many aftershocks to follow the initial quake. The damage was so cataclysmic which led to the occurrence of many casualties, about 300,000 people were injured and over one million were left homeless. Haiti is the poorest nation in the western hemisphere and is still struggling to rebuild itself. (Poster of the Haiti Earthquake, USGS Newsroom)
The Great Kanto Earthquake also known as the Tokyo-Yokohama Earthquake of 1923 hit the metropolitan area of Kanto on September 1st, 1923 around 11:58 pm. It was a 7.9 on the Richter magnitude scale, killing over one-hundred and forty thousand people due to its high magnitude and the time it happened. The earthquake struck around lunch time, when many Japanese people were at home cooking at their charcoal or gas fueled stoves. At the moment the earthquake hit, it knocked down buildings that caught flames from the stoves that fell over, enflaming the city. The fire was swept up and able to spread due to the gusts of wind that occurred for two days afterwards, resulting in firestorms. Charles Blauvelt experienced the ordeal of the fire describing the flames as “[covering] the whole city [as they] burned all day and night.” In addition to the firestorms and the earthquake itself, there was a shock because of all the fallen debris which triggered tsunamis to fill and flood Japanese cities. These tsunamis, that were about thirty feet tall, destroyed central Tokyo and immensely added to the death toll.
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.
An earthquake occurs abruptly and causes severs damage to people, property, landscape and more. A great mega-thrust earthquake, known as the Great Tohoku Earthquake has shaken Japan at 5:46:24 UTC on March 11, 2011. It caused a severe disaster, including tsunami and nuclear radiation exposure.. This mega-quake located at the latitude 38.297 degree North and longitude of 142.372 degree East, near the east coast of Honshu, Japan (USGS, 2013). An earthquake and tsunami waves caused widespread damage to many areas of Japan. People in Japan are still recovering from the damages.
The death toll climbs to over 10,000 and is still rising (Branigan 2). The disaster in Japan began without warning on Friday March 11, 2011 at 2:46pm with a 9.0 magnitude earthquake, the strongest ever recorded in the country (Fackler 3). A massive thirty-three foot high tsunami, generated by the earthquake, swept over lands in northern Japan, taking objects and debris with it. To make matters worse, the tsunami caused the cooling systems at several nuclear power plants to fail. The disaster in Japan was a tragic event, and it had a plethora of causes and effects.
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).
