The most common cause is earthquakes. When the earthquake severed the connection between the nuclear power plant and the Japan electrical grid, the diesel backup system turned on as it was supposed to. But because the plates are wedged together at this trench, that horizontal displacement still managed to thrust up enough seawater to produce the killer tsunami that hit Japan. ~ More than 20,000 death toll was recorded including 15,898+Deaths and 2,531 people missings.

Nuclear Meltdown in 2011 Earthquake in Japan. East of Japan, the Pacific plate dives beneath the overriding Eurasian plate. that were caused by the earthquake and the tsunami. "We've never seen 50-meter [slips]," said Kelin Wang, a geophysicist with the Geological Survey of Canada in British Columbia. The main reason behind the meltdown was failing of cooling systems due to problems in reactor trips and grids. It also produced a maximum 60-centimeter-high tsunami, which struck the coast half an hour after the quake. It's difficult to say whether something like this could happen elsewhere, said Wang, because no other submarine trench has as many instruments monitoring it. Similarly, Earthquake of 9.1 Magnitude caused the Tsunami producing the waves of the height of up to 38 m (i.e. The Fukushima Daiichi Nuclear Power Plant cooling system was damaged, raising fears of a meltdown. It may be due to volcanic eruptions, moving of tectonic plates, the formation of the cave in small area or explosions. 2. Or we can also say that Shindo refers to what people feel at a given location. It is also called quake( or tremor or temblor). Whereas the Richter scale is the measures of the magnitude of an earthquake or it also can be defined as the energy an earthquake releases at the epicentre. Shindo can be defined as an instrument used to measure the intensity of an earthquake of a given location. The tremors were the result of a violent uplift of … The 2011 earthquake has been the subject of intense study ever since, and the trench that produced it is the best studied in the world. An earthquake is the sudden shaking of the earth which releases the energy in the earth’s lithosphere causing the creation of seismic waves. 3. What Specifically Caused the Event? ~ The estimated loss made by this earthquake was $360 Billions +. Also regarded as the Great Tōhoku Earthquake or the Great Sendai Earthquake, several catastrophic events brought by the force of nature struck northeastern Japan on March 11, 2011. Japan government has confirmed  15,898 deaths as of June 10, 2016. The ravages of a powerful tsunami can be truly catastrophic. Japanese authorities were now faced with the challenge of cooling the Fukushima-Daiichi and stopping the leak of deadly radiation from the crippled facility. Japan earthquake, tsunami and Fukushima nuclear disaster: 2011 review. On 11 March 2011, Japan was struck by one of the most powerful earthquakes on record. After the tsunamis that occurred off the coast of Banda Aceh, Sumatra, Indonesia, in 2004, tsunami-related aspiration pneumonia with lung and brain abscesses probably caused by polymicrobial pathogens was documented in a 17-year-old girl with respiratory distress and hemiparesis. (Indoor & Outdoor), Insulating Materials | Types & Requirements of Insulating Materials, What is Boundary Wall ? The two tectonic plates involved are the Pacific plate, on which the Pacific Ocean resides, and a portion of the North American plate, on which parts of Japan sit. This also killed thousands of peoples and many peoples were missed. Answers to specific questions concerning the Earthquakes and Tsunamis. Japan's Fukushima region transformed from rural haven to ravaged wasteland when the earthquake and tsunami struck in March 2011. That clay traps water, rendering it quite slippery, he said. ~ This earthquake is also known as the Tōhoku Earthquake. Lubrication, specifically involving clay, is the key to such massive movement, said Frederick Chester, a geophysicist at Texas A&M University in College Station, and lead author of one of the studies.
