The Causes Of The T?hoku Earthquake And Tsunami

On March 11, 2011 an earthquake that measured 9.3 Richter scale occurred 43 miles of the coast of Northern Japan. This caused tremendous amounts of damage to the island of Tohouku. What happened is the quake initially destroyed buildings and property. However, a tsunami occurred, which devastated the region and the Fukushima nuclear power plant. ("Fukushima Accident")

Natural disasters are a huge challenge for the planet because of the adverse effects that are associated with them. One of the major earthquakes to have shaken the earth is the Great Sendai Earthquake or Great Tōhoku Earthquake that occurred in 2011. The event started when a powerful earthquake hit the northeastern Japan on March 11, 2011, and resulted in a widespread damage on land. A series of massive tsunamis later devastated many parts of the coastal regions of the country with the worst affected being the Tohoku region. The tsunami further resulted in a major nuclear accident that damaged distant regions on a power station located along the coast. The economic effects of the tsunami qualify it as one of the major natural disasters because it affected Japan’s economic stability as the country ended up resorting to importing as an alternative to cover the loss.

Plate tectonics is the scientific theory that attempts to explain the movements of the Earth's lithosphere that have formed the landscape features we see across the globe today” (Briney). Geology defines “plate” as a large slab of solid rock, and “tectonics” is part of the Greek root word for “to build.” Together the words define how the Earth’s surface is built up of moving plates. The theory of plate tectonics dictates that individual plates, broken down into large and small sections of rock, form Earth’s lithosphere. These fragmented bodies of rock move along each other atop the Earth’s liquid lower mantle to create the plate boundaries that have shaped Earth’s landscape. Plate tectonics originated from meteorologist Alfred Wegener’s theory, developed in the early 20th century. In 1912, he realized that the east coast of South America and the west coast of Africa appeared to piece together like a jigsaw puzzle. He further examined the globe and deduced that all of Earth’s continents could somehow be assembled together and proposed the idea that the continents had once been linked in a single supercontinent called Pangaea. To explain today’s position of the continents, Wegener theorized that they began to drift apart approximately 300 million years ago. This theory

The Fukushima disaster was caused by an earthquake and its following tsunami which caused a failure in the backup systems (World Nuclear Association, 2016). The tsunami knocked out the generators that powered the cooldown processes for three of the Fukushima power plants which caused the radiation leaks and other complications. Consequentially, the disaster was initially classified as a level 5 on the INES scale. Further investigation after the disaster was under control changed it to a level 7 disaster, the highest level on the INES scale. The estimated radioactive releases were about one tenth of Chernobyl, the worst nuclear disaster in history.

On March 14, 2011, Anne Applebaum created an account of the events that had occurred earlier that day in Japan. She recalled the shattering earthquake that followed a tsunami and destroyed towns such as Rikuzentakata, a town of 25,000 people (Applebaum 229). The earthquake also agitated Fukushima Daiichi, one of Japan’s nuclear power complexes. Unfortunately, all three reactors lost their ability to cool the steaming water and had to be flooded. The seawater effectively destroyed the plant before more explosions occurred. As a result, radioactive steam had to be released. Applebaum glorified the Japanese in their “technological brilliance” and their ability to cope in extreme circumstances (Applebaum 230). Although the regulations are strict

As of April 10, 2015, earthquake and tsunami caused the death total of 15,891 people, ravaged large areas of the Japanese countryside, and continues to cause

When an 9.0 magnitude earthquake rocked Japan on March 11th, 2011, it was the first of a series of horrific events that Japan would be forced to endure. Many homes, families, properties, and belongings were lost on that day. And when the tsunami rolled over the island, many believed that it was over for them. Not only had people’s lives been put in disarray and desolation, but there had not even been simple necessities available. Food. Water. Communications. And electricity. When the Fukushima Daiichi nuclear plant had been hit by the earthquake and tsunami, the reactors were shut down and so was the electricity. Over the course of months the reactors suffered, extreme heat, fires, hydrogen explosions, and radiation exposures. At the time,

According to the records of earthquake intensity, this is the strongest earthquake occurred in Japan and one of the most powerful earthquakes in the world ( ). When the Pacific land crashed down and the North American land slide up, the resulting of landslide and outburst of the bottom turn to create earthquake in the Pacific Ocean, and it was the biggest impact in 1200 years. Furthermore, the earthquake occurred from 130 kilometer east of the city of Honshu, Japan on March 11, 2011, and the main shock lasted for 40 minutes. The earthquake created magnitude scale to 9.0 Mw, and 165-foot movement occurred to the seafloor during the earthquake ( ). Moreover, at that time, most city of Japanese affected by that earthquake, and a nuclear power industry is one of the victims which was crashed by the earthquake. Because of that, it release of radiation to large area not only in Japan but also get oversea to another country such as China, Viet

In the last decade alone, there have been a number of natural disasters that have caused substantial physical damage and great emotional distress to the people who were affected. The aftermath of a natural disaster presents many concerns; communities become displaced, health risks and complications occur, food scarcity becomes a result of lost crops, and emotional aftershocks become apparent. Some Haitian’s have yet to recover from the earthquake they experienced in 2010. (Davis, 2015) “According to FEMA, the total damage for hurricane Katrina is estimated at $108 billion.” (CNN News, 2015), and 86,000 lives were taken in the earthquake of Pakistan in 2005 (EERI, 2006). In 2008, communities of Sichuan, China, endured a 7.9 magnitude earthquake that collapsed several buildings, killing over 87,000 people. Buildings had very poor infrastructures, which caused the destruction of many local schools. This contributed to the deaths of thousands of school aged children (BBC News, 2013). However, the Boxing Day tsunami was one of the largest and most destructive natural disasters of

Tsunamis occur when there is sudden movement in an extensive body of water such as earthquakes, landslides on the sea floor, major volcanic eruptions or meteorite impacts. The most common source of a tsunami is earthquakes, which are another type of geomorphic hazard that is caused by the friction and stress that tectonic plates put on each other. Tsunamis primarily occur in coastal or island regions where there is a tectonic border or what is known as the ring of fire. As shown in the diagram below the ring of fire is located along the coastal and island regions of the world.As a result of the Pacific Plate diving beneath the Eurasian plate, on March 11, 2011, there were 2 geomorphic hazards, a magnitude-9 earthquake struck north Japan, which caused a deadly tsunami that reached heights of 39 meters. The destructive dilemma was dubbed ‘The Great Sendai Disaster’. The earthquake was caused by multiple centuries of stress on the tectonic plates surrounding the island. The earthquake caused a tsunami that reached the height of 39 meters (128 feet). Japanese scientists had previously discovered that there was another tsunami just like the one in 2011 that took place in 869 AD. But their warning was unhindered. The tsunami, which occurred in 869 AD, was caused by the same tectonic fault as the 2011 tsunami. The epicenter of the earthquake was off the northeast cost of Japan leading to a devastating tsunami that killed many and left many wishing they were. The massive earthquake caused an upward wave that headed towards the city of Sendai. Researches have recently uncovered a thin layer of clay that lubricated the fault zone causing the deadly tectonic slip, thus creating a tsunami that could wipe out an entire city as it did in 2011.The aftermath of the 2011 tsunami and earthquake was not pretty; it caused many deaths, injuries, traumas, financial difficulties, destruction of property, health bills and the destruction of the landscape as a whole. The natural disaster caused nearly 16,000 casualties and there are an estimated 2,500 people still reported missing. Although drowning caused most deaths others include, crushed by debris, suicide and diseases caused by nuclear radiation (cancer) spilled from nuclear

Good morning, at this moment we have breaking news, an catastrophic eartquake of 9 magnitude on the richter scale hit Japan a few minutes ago, this event caused a tsunami with waves up to ten meters. The epicentre was aproximately 70 kilometers east of the Oshika peninsula of Tokio and the hipocenter at an underwater depth of approximately 29 kilometers. The number of casualities is 24608 and the death tool is estimated around 15894 dealths. The lenght was aproximate six

There was an absolutely massive social impact on the 2011 Japanese tsunami with a total death toll of around about 1 433 people dead and a further 63 000 people in shelters around the country. There was a 12 mile (12.3 kilometre) radius with more than 70 000 people in that area. There was another 136 000 people in the next 15 mile (21.1kilometre) radius. Everyone within that 15 mile radius was advised to go but of course, not everyone

On March 11th, 2011, the northern section of Japan was hit by a 9.0 magnitude earthquake, followed by a 15 meter tsunami, causing the death of over 15000 people. (Spacey) Even though the earthquake and the tsunami caused a tremendous amount of deaths in the northern region of Japan, the meltdown of the Fukushima nuclear power plant caused a severe damage to northern Japan’s ecosystem that people still cannot go back to their homes; despite it is 4 years after the disaster. After the earthquake, the tsunami destroyed the power supply used by Fukushima’s three nuclear power stations, causing severe levels of meltdown to be occurred inside the reactors in the timespan of 3 days. It was not until 2 weeks after the tragedy, when the reactors were finally stabilized, and took several months to approach what is called a “cold shutdown condition”, in which the fission in the reactors are completely stopped.(Fukushima A)

The devastation that occurred on March 11, 2011. An earthquake destroyed northeastern Japan, unleashing a terrible tsunami. As of February 2017, there were still about 150,000 evacuees who lost their homes, 50,000 of them were still living in temporary housing. Honshu earthquake on March 11, 2011 was a surprise. This unexpected disaster was not the largest or the deadliest earthquake and tsunami to strike. More than 120,000 buildings were destroyed, 278,000. The total economic cost could reach up to $235 billion, the World Bank estimated, making it the costliest natural disaster in world history. That record goes to the 2004 Banda Aceh earthquake and tsunami in Sumatra, which killed more than 230,000 people. The March 11 earthquake started on a Friday at 2:46 p.m. local time. Japan's scientists had forecast a smaller earthquake would strike the northern region of Honshu, the country's main island. The direct financial damage from the disaster is estimated to be about $199 billion dollars. In Japan, residents are still recovering from the disaster. In a subduction zone, one plate slides beneath another into the mantle, the hotter layer beneath the crust. Less than an hour after the earthquake, the first of many tsunami waves hit Japan's coastline. In the decade before the 2011 Tohoku earthquake, a handful of Japanese geologists had begun to recognize that a large earthquake and tsunami had struck the northern Honshu region in 869. The country recently unveiled a newly

In March of 2011, a magnitude 9 earthquake hit Japan, releasing a dangerous tsunami. Japan was not expecting the magnitude of the earthquake and tsunami, and endured much hardship after the disaster. The effects of the tsunami can still be seen in Japan today through its residents, economy, and through actions that have been taken to further protect residents from future disasters. Though the Japan 2011 tsunami is one of the most destructive tsunamis ever recorded, dangerous tsunamis continue to take place across the globe. The Japan 2011 tsunami not only affected the inhabitants of Japan, but also affected people around the world. After disasters such as this, each area must endure the aftermath of the disaster and recover from the effects.
