Answers to specific questions concerning the Earthquakes and Tsunamis. Second, it crippled Japan's nuclear industry. In May 2011, UK chief inspector of nuclear installations Mike Weightman traveled to Japan as the lead of an International Atomic Energy Agency (IAEA) expert mission. What Causes a Tsunami? (Indoor & Outdoor), Insulating Materials | Types & Requirements of Insulating Materials, What is Boundary Wall ? Similarly, Earthquake of 9.1 Magnitude caused the Tsunami producing the waves of the height of up to 38 m (i.e. Japan's Fukushima region transformed from rural haven to ravaged wasteland when the earthquake and tsunami struck in March 2011. "Nowhere else do we have such a massive monitoring system. They also believe that this layer of clay leads to sliding of plates to an incredible distance of about 50 m causing earthquake and tsunami. "We've never seen 50-meter [slips]," said Kelin Wang, a geophysicist with the Geological Survey of Canada in British Columbia. ~ More than 20,000 death toll was recorded including 15,898+Deaths and 2,531 people missings. 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. This helped confirm the fact that something else was going on—namely the clay lubrication. 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. Within a magnitude of between 8.9 and 9.1, the earthquake was devastating. This reduces the loss by alerting railway department and industries assembly lines. Or we can also say that Shindo refers to what people feel at a given location. that were caused by the earthquake and the tsunami. Since 1960 we have experienced four such mega events in the world including the 2011 Japan earthquake (image on left) that caused huge destruction along with the tsunamis… Tsunami is the effect of the earthquake so it is not possible without an earthquake. At 2:46 pm (0546 GMT) of March 11, 2011, a 9.0-magnitude underwater quake struck the Pacific seabed roughly 130 kilometres (80 miles) east of Japan's Miyagi prefecture. diving of Pacific plate beneath the overriding Eurasian plate in eastern Japan. 3. Great Tohoku, Japan Earthquake and Tsunami, 11 March 2011. After the power cut, nuclear fission stopped and caused a meltdown. Shindo is similar to the Modified Mercalli intensity scale used in the united states or the lieu scale used in China. See the percentages on the … After the earthquake, scientists drilled into the subduction part of the earthquake and found slippery clay layer lining the fault. 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. The tsunami hit the coasts of Japan just after  30 minutes after the earthquake. ", Normally, when two plates collide, there is friction. Experts calculate the fault—or the boundary between two tectonic plates—in the Japan trench slipped by as much as 164 feet (50 meters). (See "Japan Tsunami: 20 Unforgettable Pictures."). Experts were able to take core samples of sediment and rock from the trench—located in 23,000 feet (7,000 meters) of water—thanks to a sophisticated drilling ship. All rights reserved.

In this way, the earthquake range measured in the Shindo scale. What are the effects of japan tsunami on the environment? Remember, tsunamis are an after-effect of an earthquake. Although many structures were destroyed by an earthquake; the Japanese never let it destroy their thought and feeling to move towards the peak. As the Pacific plate dives into a trench off the coast of Japan, small portions of the clay get smeared along the plate boundary, Chester explained. The vertical displacement of seawater was the cause of the tsunami that expanded away from the earthquake site. Although many earthquakes and tsunami hit Japan every year; It recovers the wound given by nature in a dramatic way and again moves towards the peak of development & Technology with discipline. The ravages of a powerful tsunami can be truly catastrophic. Japan earthquake, tsunami and Fukushima nuclear disaster: 2011 review. A magnitude-9.0 earthquake struck off Japan’s northeastern coast. This was caused by the hitting of high tidal waves on electrical power plants and lower part of nuclear plants that failed the power supply system. The 2011 Tohoku earthquake struck offshore of Japan, along a subduction zone where two of Earth's tectonic plates collide. That Japan was not adequately prepared for the tsunami that hit the northeastern Honshu coast on March 11, 2011, first became apparent at the Fukushima Daiichi nuclear power plant. These quakes caused little damage even though the main rupture was only 8 kilometers deep. 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. Even though the earthquake produced a 1,100° to 2,200°F (600° to 1,200°C) temperature increase, the amount of friction that had to be overcome to produce the fault slip wasn't as large as researchers expected, said Brodsky. "[This] was right at the edge of what engineering could do," Brodsky said. Pope Francis will meet in Japan with victims of the enormous earthquake and tsunami of 2011 that triggered the Fukushima nuclear meltdown -- sometimes referred to as the "triple disaster". ", The 2011 Japan Tsunami Was Caused By Largest Fault Slip Ever Recorded, https://www.nationalgeographic.com/news/2013/12/the-2011-japan-tsunami-was-caused-by-largest-fault-slip-ever-recorded.html. 1. Japanese authorities were now faced with the challenge of cooling the Fukushima-Daiichi and stopping the leak of deadly radiation from the crippled facility. Height of 12 storey building). Two days prior to the massive temblor, a magnitude-7.2 earthquake with three aftershocks greater than magnitude 6.0 hit offshore eastern Honshu. Traces of radioactive isotopes like caesium-134 & caesium-137 was found on seawater during the test conducted in 2014 and 2015. This also killed thousands of peoples and many peoples were missed. The most powerful earthquake recorded in Japanese history, magnitude 8.9. UPDATED March 13, 2011 How Shifting Plates Caused the Earthquake and Tsunami in Japan Another main effect of this Tsunami was a Nuclear meltdown. 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. Fri 11 Mar 2011 04 .11 EST. Based on the limited data recorded from that earthquake, the fault slipped by 98 to 131 feet (30 to 40 meters). The Japan Trench Fast Drilling project enabled researchers to get out to the fault zone about a year after the earthquake and drop instruments down to measure temperature anomalies—the sudden slips during an earthquake can generate vast amounts of heat—and to bring up samples of the fault zone itself for analysis. The 11 March 2011, magnitude 9.0 Honshu, Japan earthquake (38.322 N, 142.369 E, depth 32 km) generated a tsunami observed over the Pacific region and caused tremendous local devastation. What Specifically Caused the Event? On 11 March 2011, Japan was struck by one of the most powerful earthquakes on record. Most of the movement occurred horizontally, he explained. Japan earthquake and tsunami of 2011 A massive tsunami, generated by a powerful undersea earthquake, engulfing a residential area in Natori, Miyagi prefecture, northeastern Honshu, Japan, on … That clay traps water, rendering it quite slippery, he said. Largest Fault Slip Ever Recorded Clay lubricated the fault zone in the Japan trench, A nuclear meltdown in Fukushima Daiichi Nuclear Power Plant is one of the biggest nuclear accident happened in history since the 26 April 1986 Chernobyl disaster. A thick layer of clay sits atop the Pacific plate, which is getting dragged under a portion of the North American plate. 11 of Japan's 50 nuclear reactors were immediately closed after the disaster, reducing the country's electricity generation by 40%. Thousands of lives were saved by early warning system which alerted the citizens just a minute before the earthquake with the help of the alarm system and sending text messages. The tsunami caused the greatest devastation and over 17,000 deaths in Japan, where waves reached over 40 m or 130 ft. high. Whereas at Shindo five objects start to fall and at the Shindo (6 and 7) heavier damage occurs. 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. ~ The magnitude of the earthquake was 9-9.1. The Fukushima Daiichi Nuclear Power Plant cooling system was damaged, raising fears of a meltdown. 2011 Japan Tsunami and 2004 Indian Ocean Tsunami Margaret Howson. A recent study had shown that this earthquake was a result of the temblor completely after a century. Tsunamis are caused by violent seafloor movement associated with earthquakes, landslides, lava entering the sea, seamount collapse, or meteorite impact. In a subduction zone, one plate slides beneath another into the mantle, the hotter layer beneath the crust. ~ The estimated loss made by this earthquake was $360 Billions +. The only earthquake doesn’t increase the death toll; many peoples died and missed because of the Tsunami. The magnitude 9.0 Tohoku-Oki … Documentary exploring the scientific factors behind themagnitude 9 earthquake and the resultant tsunami thatstruck Japan on March 11. Not only did they find evidence of this thin layer of lubricating clay, but experts were also able calculate how much heat and friction was involved. The great plates are rough and stick together, building up energy that is released as earthquakes. Other similarly large magnitude earthquakes, including the 9.1 Sumatra event in 2004, resulted in a 66-to-82 foot (20-to-25 meter) slip in the fault. Japan … Two years ago, the sea off the coast of Japan reared up and swept away tens of thousands of lives in a devastating natural disaster. ~ Earthquake strike occurred on March 11, 2011, at 05:46:23 UTC ( 14:46 JST). The main reason behind the meltdown was failing of cooling systems due to problems in reactor trips and grids. The center of the earthquake that causes the … This is what caused the Boxing Day tsunami in the Indian Ocean in 2004 and it is also the reason behind the 2011 Japan tsunami. The 2011 Great East Japan Earthquake and Tsunami led to direct and indirect losses as well as the deaths of many vulnerable members of Japan… Tsunami is also called Harbour Wave in the Japanese language. ~ The shaking lasted for about 6 minutes. It is also called quake( or tremor or temblor). After the 2004 Boxing Day tsunami, much of the world's effort to defend against tsunami concentrated on tsunami warning and evacuation. "But clay almost removes any braking properties.". | Advantages, Disadvantages & Uses, What is Irrigation? 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. The most common cause is earthquakes. © 1996-2015 National Geographic Society, © 2015- They also reported the missing of more than 2,531 citizens. An earthquake is the sudden shaking of the earth which releases the energy in the earth’s lithosphere causing the creation of seismic waves. The main cause of this earthquake was diving of Pacific plate beneath the overriding Eurasian plate in eastern Japan. 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. 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. It may be due to volcanic eruptions, moving of tectonic plates, the formation of the cave in small area or explosions. The most-powerful earthquake in Japan's recorded history struck off the country's northeast coast on Friday, triggering a massive tsunami and leaving hundreds of people dead, injured or missing. What caused the tsunami? The 2011 Japan Earthquake and Tsunami: On March 11, 2011 Japan was hit by the largest earthquake in its recorded history. "We think that's responsible for allowing the incredibly large slip we observed near the trench. It is estimated that the initial tsunami wave took 10 to 30 minutes to make its first landfall. The quake caused a giant wave out at sea, called a tsunami, which grew to 10 metres high. East of Japan, the Pacific plate dives beneath the overriding Eurasian plate. ~ It was one of the biggest earthquakes in Japans history and top 5 largest earthquakes in the history of the world after seismological recording began. Tsunami waves smashed the coast, causing massive damage and flooding. To understand how earthquakes cause tsunamis we must first fully understand what causes earthquakes. Like many around the world, I sit transfixed by the images coming this morning from northern Japan, where a devastating earthquake and tsunami … The main finding of this mission, as reported to the IAEA ministerial conference that month, was that risks associated with tsunamis in several sites in Japan had been underestimated. It is measured with a Richter Magnitude scale. ~ 72 Km east of the Oshika Peninsula was the Hypocenter. You can think of friction like a brake, Chester explained. Japan government has confirmed  15,898 deaths as of June 10, 2016. 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 unprecedented data haul that enabled Chester and colleagues to figure out what happened during the 2011 earthquake is courtesy of a rapid response by the Japan Agency for Marine-Earth Science and Technology, said Emily Brodsky, a geophysicist at the University of California, Santa Cruz, and a co-author of one of the studies. | Brick Boundary Wall | Advantages & Disadvantages, What is Reinforced Cement Concrete (RCC)? The Shindo scale range from one to seven wherein Shindo one, a slight earthquake is felt by the people who are not moving wherein Shindo (2-4) minor earthquake occurs which does not cause any damage. The 2011 tsunami was caused by a magnitude 9.0 earthquake in Sendai, Japan on March 11, 2011. On March 11, 2011 at 2:45 local time, a 9.0 magnitude earthquake occurred 81 miles (130 km) off the east coast of Sendai, Japan, triggering a massive tsunami. ~ This earthquake is also known as the Tōhoku Earthquake. Christoph Grützner | June 1, 2011|09:37 (UTC) The environmental effects we are talking about are geological phenomena (sedimentation, erosion, hydrological changes, landslides, rockfalls, etc.) After the nuclear meltdown; Evacuation zone of about 20km radius was declared because of exposure of radiation on the atmosphere.
