Japan – Fukushima
Introduction
On March 11, 2011 at 2:46 PM, Japanese time, an 8.9 magnitude earthquake hits, but was later upgraded to a 9.0 magnitude earthquake, happens 231 miles northeast of Tokyo, Japan, at a depth of 15.2 miles. The pacific tsunami-warning centre sends out a warning to Japan all the way to The United States of America. Around an hour later after the earthquake the waves hits. The waves got up to 30ft high when they hit the Japanese coast. The waves caused widespread devastation washing away cars like they were sticks, collapsing buildings and destroying roads and highways.
Causes
This Tsunami costed the Japanese government 25 trillion yen ($300 billion) dollars. The earthquake happened because of the thrust faulting on or around the subduction zone interface plate boundary between the pacific and North American plates. According to scientists who has look at this disaster Japan has shifted 8 feet (2.4 meters) East towards North America. The earthquake has also caused the earth to move between 4 and 6.5 (10–16cm) inches on its axis. This earthquake caused the tsunami because when the earthquake happened it suddenly shifted the sea floor in vertical motion, which moved the water Colum above it. This process started a series of giant waves called a tsunami.
Impacts
For the Japanese government this was the worst thing that could happen to them in the way that they lost a lot of citizens but also financially. This effected not only the Japanese government with damage costs but also the manufacturing business, exporting business and the insurance business. The Insurance companies claims ran into the billions. The manufacturing business was suspended along with car exports.

Imagine if a 9.0 earthquake struck the West Coast today, resulting in a giant tsunami. Coastal towns would be washed away or completely isolated, and electricity would be lost (FOX5). There would be $70 billion in damage and people would only have 15 minutest to evacuate or move to higher ground resulting in 10,000 deaths (FOX5). This sounds like a plot for a scary movie, but this is actually a reality. The Oregon Coast in located on a subduction zone, which makes it very susceptible to major earthquakes and tsunamis. With the Cascadia subduction zone running along he West Coast the threat of a major tsunami is very real.
Tsunamis can go the same speed as a jetliner and that massive wave can out run the fastest runner. When there is a lot of waves at once, or the water goes back that is a sign that a tsunami is coming. If that tsunami is far then people need to get to the tallest and strongest building there is in the city that way they are safe and helicopter can pick them up. Tsunamis can wipe out an entire city or 1/4 of the country. Tsunamis can last up to an hour, or more.
The tsunami in Thailand that occurred on December 26, 2004, was by far the largest tsunami catastrophe in human history. It was triggered by a magnitude 9.1-9.3 earthquake along the Indian-Australian subduction zone off the northern coast of Sumatra. The tsunami waves traveled primarily in the east to west direction and caused major damage along the coasts of southern Thailand. Unpredictably, it was a violent earthquake beneath the sea that initiated the massive waves and struck more than a dozen countries in Southern Asia. It also destroyed thousands of miles of coastline and even submerged entire islands permanently. Throughout the region, the tsunami killed more than 150,000 people, and a million more were hurt, homeless, and without food or drinkable water, making it perhaps the most destructive tsunami in the modern history. In spite of peninsular Thailand's location facing the northern part of this subduction zone, the lack of any written historical records, together with the lack of any major local seismic activity, the tsunami caused thousands of fatalities and huge economic losses in the popular tourist regions in Thailand. Immediately after the disaster, numerous organizations and individual citizens have helped out and contributed to this devastating tsunami. Indeed, the tsunami in Thailand was a worldwide event, with significant wave action felt around the world. In this context, I am focusing more on the key features of the tsunami’s natural causes, the psychological effects on citizens, the perspective of socio-economic impacts and the consequences of the tsunami calamity.
Predicting tsunamis is not a precise art; unlike some natural disasters, tsunamis are not climate based and do not happen during a particular season. In the case of the Sumatra earthquake and tsunami, an ocean-based sensors and a warning system in place could have been an enormous help. At the time of the tsunami, there were no ocean-based sensors in place in the Indian Ocean—which lead to a lack of knowledge of the tsunami, resulting in a lack of a plan to move to higher ground resulting in 230,000 were killed due to the Boxing Day
Out of all the natural disasters that we talk about in class, the most deadly would have to be a Tsunami. Compared to earthquakes, Tsunamis have cause more deaths since 1945. A Tsunami is likely to strike anywhere on the west coast, including Santa Cruz in California – United States – North America – 36:58:24N 122:02:09W. A Tsunami is a giant “wave” of water that is caused by a sudden shift in the sea floor. The wave is a result of the water attempting to regain its equilibrium, which is driven by gravity. The size of the wave is determined by how much the sea floor is moved vertically, and how quickly it shifts. A greater water depth helps as well. They can travel up to five hundred miles an hour and have wave heights of one hundred feet. Earthquakes are the leading cause of Tsunamis. People who live in California are well aware of earthquakes that are frequently caused by the San Andreas Fault. However, not many are aware of the results of earthquakes that occur out in the Pacific Ocean. Tsunamis have also been referred to in the past as seismic sea waves, but Earthquakes aren’t the only cause of this phenomenon. Landslides, nuclear explosions, volcanic eruptions, and extra terrestrial impacts also have great water displacement results.
Beginning with Chile, it affected the cities of Valdivia, Puerto Montt, Rio Negro, Temuco, to name a few. It also affected the coast of California, New Zealand, Australia and Kamchatka. This affected the people of Chile plenty. It is believed that most of the loss of life were caused by the tsunami. The earthquake affected by speeding up Earth’s rotation. It shorted earth days by 1.26 millionths of a second. It also shifted Earth’s figure axis by about three inches. While all this happen in 1960, it was a cause of the 2010 earthquake that occur in Chile. This time it was a magnitude of 8.8 and like I mentioned, all this occur from the earthquake in 1960. However, the diving tectonic plate at the epicenter of the 8.8 magnitude, helped to temporarily redistribute mass on Earth. Unfortunately, as every Earthquake, there is damages. $550 million damage in southern Chile. Different sources have estimated the monetary cost ranged from US$400 million to 800 million (or 2.9 to 5.8 billion in 2011 dollars, adjusted for inflation). Furthermore, besides the dollar amount in damages that was mentioned in this paper, the tsunamis played a factor on the
When looking at the aftermath of the atomic bomb in both Nagasaki and Hiroshima the devastation it caused is evident. The majority of the population in Japan could have never imagined such a catastrophic event. On August 6, 1945 and August 9, 1945 massive amounts of lives were changed forever when an atomic bomb fell from the sky and created an explosion as bright as the sun. These two bombs were the first and only accounts of nuclear warfare. (“Atomic Bomb is…”) The impact that the two bombs left on the cities of Japan was tremendous. The bombing of Nagasaki and Hiroshima devastated the country through structural damage, long term medical effects, expenses, and the massive loss of life.
I. (Gain Attention and Interest): March 11, 2011. 2:45 pm. Operations at the Fukushima Daiichi Nuclear Power Plant continued as usual. At 2:46 pm a massive 9.0 earthquake strikes the island of Japan. All nuclear reactors on the island shut down automatically as a response to the earthquake. At Fukushima, emergency procedures are automatically enabled to shut down reactors and cool spent nuclear fuel before it melts-down in a catastrophic explosion. The situation seems under control, emergency diesel generators located in the basement of the plant activate and workers breathe a sigh of relief that the reactors are stabilizing. Then 41 minutes later at 3:27 pm the unthinkable occurs. As workers monitored the situation from within the plant, citizens from the adjacent town ran from the coastline as a 49 foot tsunami approached. The tsunami came swiftly and flooded the coastline situated Fukushima plant. Emergency generators were destroyed and cooling systems failed. Within hours, a chain of events led to an explosion of reactor 1 of the plant. One by one in the subsequent days reactors 2, and 3 suffered similar fates as explosions destroyed containment cases and the structures surrounding the reactors (Fukushima Accident). Intense amount...
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.
Additionally, this earthquake occurred on a thrust fault. This fault was a subduction zone slip which occurred primarily beneath the ocean were the Pacific plate plunges underneath the North American plate. This sudden upward movement of the sea floor along the rupturing fault generated a massive tsunami. This vertical deformation

While the early warning saved thousands of people, the Japan’s Meteorological Agency underestimated this earthquake as the subduction zone of Japan should not produce the magnitude 9.0 quake (Oskin, 2013a). The Tohoku Earthquake and its tsunami approximately killed 16 thousand people, injured 6 thousand people and around 3 thousand people were missing. Most people died from drowning. Around 300 thousand buildings, 4000 roads, 78 bridges, and many more were affected by the earthquake, tsunami, and fires from leaking oils and gas. Electricity, telecommunication, and railways were severely damaged. The debris of 25 million tons was generated and carried out to the sea by water (BBC News, 2012). The country’s authorities estimated more than 309 billion US dollars of damages. Landslides occurred in Miyagi and liquefaction in Chiba, Tokyo, Odaiba, and Urayasu (USGS, 2013). Furthermore, the tsunami destroyed protective tsunami seawalls. Approximately 217 square miles of Japan covered in water (Oskin,
As the tectonic plates slide over each other, they cause earthquakes. Earthquakes produce various damaging effects, this includes damage to structures of buildings, bridges and other standing formations which then result in injuries and people getting killed, wildlife getting disrupted as well as humans. An earthquake can affect the earth as it’s easier to let the lava come out of the earth. Tsunamis- Can cause financial problems such as home loss, job loss which will then result in being homeless, loss of crops and food supplies which causes a lot of harm to us ‘humans’. A tsunami is a series of waves that send surges of water that can travel thousands of miles.
There was a multitude of causes of the disaster in Japan. The first cause was a 9.0 magnitude earthquake that occurred off the coast of Japan. Japan is located in “The Ring of Fire,” an area in the Pacific Ocean that has multiple faults and earthquakes (Pedersen 13). Tectonic plates shifted off the North Pacific coast of Japan and created a massive earthquake. The next cause was a thirty-three foot wall of water that swept over cities and farmland in Japan (Branigan 2). Martin Fackler, a journalist, stated, “The quake churned up a devastating tsunami” (Fackler 3). The tsunami reached speeds of 497 miles per hour while approaching Japan (Fackler 3). The third and final reason of the disaster was that the cooling systems at multiple nuclear power plants failed. At Fukushima, a nuclear power plant in Sendai, Japan, the radioactive rods began to overheat due to the absence of water, which cools it. Explosions occurred at three of the reactors, which spewed radiation into the air (“Comparing nuclear power plant crises”). In conclusion, the earthquake, tsunami, and nuclear power plant issues were the causes of the disaster in Japan, but they also had a myriad of effects.
