tohoku earthquake magnitude

[393][394], The quake gave scientists the opportunity to collect a large amount of data to model the seismic events that took place in great detail. , 2011; Simons et a l. , 2011). The temblor also shortened the length of a day by about a microsecond. [212] As of March 2012, Japanese police data showed that 70% of the 3,279 still missing were aged 60 or over, all found, including 893 in their 70s and 577 in their 80s. [373] There was no damage to the Historic Monuments and Sites of Hiraizumi in Iwate Prefecture, and the recommendation for their inscription on the UNESCO World Heritage List in June was seized upon as a symbol of international recognition and recovery.

While the Japan Trench was known for creating large quakes, it had not been expected to generate quakes above an 8.0 magnitude. [36][141], Like the 2004 Indian Ocean earthquake and tsunami, the damage by surging water, though much more localized, was far more deadly and destructive than the actual quake. [302] As the nuclear crisis entered a second month, experts said that Fukushima Daiichi, while not the worst nuclear accident ever, was the most complicated. [132][133] Just over an hour after the earthquake at 15:55 JST, a tsunami was observed flooding Sendai Airport, which is located near the coast of Miyagi Prefecture,[134][135] with waves sweeping away cars and planes and flooding various buildings as they traveled inland. [338], A tsunami flooded Sendai Airport at 15:55 JST,[134] about 1 hour after the initial quake, causing severe damage. Part 1: A Brief Survey of Religious Mobilization after the Great East Japan Earthquake Disasters". "Spatial distribution and focal mechanisms of aftershocks of the 2011 off the Pacific coast of Tōhoku Earthquake" by Y. Asano, T. Saito, Y. Ito, K. Shiomi, H. Hirose, T. Matsumoto, S. Aoi, S. Hori, and S. Sekiguchi. [325], On 13 March the lowest-level state of emergency was declared regarding the Onagawa plant as radioactivity readings temporarily[326] exceeded allowed levels in the area of the plant. [248] The earthquake and tsunami created an estimated 24–25 million tons of rubble and debris in Japan. [171], A Japanese government study found that 58% of people in coastal areas in Iwate, Miyagi, and Fukushima prefectures heeded tsunami warnings immediately after the quake and headed for higher ground. [279][280][281] Japanese government continue to ask the public to conserve electricity for several years until year 2016, when it predicted that the supply will be sufficient to meet demand, thanks to the deepening of the mindset to conserve electricity among corporate and general public, addition of new electricity providers due to the electricity liberalization policy, increased output from renewable energy as well as fossil fuel power stations, as well as sharing of electricity between different electricity companies. Early estimates placed insured losses from the earthquake alone at US$14.5 to $34.6 billion. 466 Sk. [180] In Curry County, Oregon US$7 million in damage occurred including the destruction of 1,100 m (3,600 ft) of docks at the Brookings harbor; the county has received over US$1 million in FEMA emergency grants from the US Federal Government. [203], Scientists say that the subsidence is permanent. [42], Soil liquefaction was evident in areas of reclaimed land around Tokyo, particularly in Urayasu,[96][97] Chiba City, Funabashi, Narashino (all in Chiba Prefecture) and in the Koto, Edogawa, Minato, Chūō, and Ōta Wards of Tokyo. [395] Gravimetric data from the quake have been used to create a model for increased warning time compared to seismic models, as gravity fields travel faster than seismic waves. This motion pushes the upper plate down until the accumulated stress causes a seismic slip-rupture event. [177] The United States National Tsunami Warning Center issued a tsunami warning for the coastal areas in most of California, all of Oregon, and the western part of Alaska, and a tsunami advisory covering the Pacific coastlines of most of Alaska, and all of Washington and British Columbia, Canada. Hence, earthquakes in this area with magnitudes of about 7 since 1926 had only released part of the accumulated energy. [300], The number 2 reactor at Tōkai Nuclear Power Plant was shut down automatically. 1. The plant's three reactors automatically shut down without damage and all safety systems functioned as designed. The Japanese Foreign Ministry confirmed the deaths of nineteen foreigners. Kansai Electric Power Company (Kepco) could not share electricity, because its system operated at 60 hertz, whereas TEPCO and TEP operate their systems at 50 hertz; the disparity is due to early industrial and infrastructure development in the 1880s that left Japan without a unified national power grid. Without ventilation, gas accumulated within the reactor containment structures and eventually exploded. The warning system was supposed to be updated about 15 minutes after the earthquake occurred, by which time the calculation for the moment magnitude scale would normally be completed. The epicenter of the earthquake was about 130 km (81 miles) southeast of Aomori, Tohoku region, with a depth of 60 km (37 miles). [51] In addition, some three thousands extra deaths have been identified as "earthquake-related deaths",[209][210] bringing the total number of deaths caused by the disaster to 19,575 as of 2017 September. [38] These data are expected to be used in a variety of ways, providing unprecedented information about how buildings respond to shaking, and other effects. [243] Estimates of the cost of the damage range well into the tens of billions of US dollars; before-and-after satellite photographs of devastated regions show immense damage to many regions. Rolling blackouts of approximately three hours were experienced throughout April and May while TEPCO scrambled to find a temporary power solution. [313], Radioactive iodine was detected in the tap water in Fukushima, Tochigi, Gunma, Tokyo, Chiba, Saitama, and Niigata, and radioactive caesium in the tap water in Fukushima, Tochigi and Gunma. In Sendai, a 145,000-barrel (23,100 m3)-per-day refinery owned by the largest refiner in Japan, JX Nippon Oil & Energy, was also set ablaze by the quake. [205], In Japan, the National Police Agency has confirmed 15,899 deaths,[206] 6,157 injured,[207] and 2,529 people missing[208] across twenty prefectures. 3. Japan specifically requested assistance from teams from Australia, New Zealand, South Korea, and the United States. [256][257], The Fujinuma irrigation dam in Sukagawa ruptured,[258] causing flooding and the washing away of five homes. Most of these deaths occurred during the first six months after the earthquake and the number dropped thereafter, but as time has passed, the number has continued to increase. [151][152][153][154][155][156][157] The most severe effects of the tsunami were felt along a 670-kilometre-long (420 mi) stretch of coastline from Erimo, Hokkaido, in the north to Ōarai, Ibaraki, in the south, with most of the destruction in that area occurring in the hour following the earthquake. The seismic events shown took place on that same day, between 01h41 and 23h59 (GMT). [136][137] The impact of the tsunami in and around Sendai Airport was filmed by an NHK News helicopter, showing a number of vehicles on local roads trying to escape the approaching wave and being engulfed by it. [201][202], The Geospatial Information Authority of Japan reported land subsidence based on the height of triangulation stations in the area measured by GPS as compared to their previous values from 14 April 2011. Also, observed data from tidal meters that were located off the coast were not fully reflected in the second warning. The GPS station located nearest the epicenter moved almost 4 m (13 ft). [51] The earthquake and tsunami also caused extensive and severe structural damage in north-eastern Japan, including heavy damage to roads and railways as well as fires in many areas, and a dam collapse. 2. [86][fn 2] The largest individual recording in Japan was 2.7 g, in Miyagi Prefecture, 75 km from the epicentre; the highest reading in the Tokyo metropolitan area was 0.16 g.[89], Portions of northeastern Japan shifted by as much as 2.4 metres (7 ft 10 in) closer to North America,[38][39] making some sections of Japan's landmass wider than before. [99], Shinmoedake, a volcano in Kyushu, erupted three days after the earthquake. The thousands of bodies, however, exceeded the capacity of available crematoriums and morgues, many of them damaged,[233][234] and there were shortages of both kerosene—each cremation requires 50 litres—and dry ice for preservation. Some of the first research to come from the archive was a 2014 paper from the Digital Methods Initiative in Amsterdam about patterns of Twitter usage around the time of the disaster. Kyodo News, "Survivors in trauma after life-changing nightmare day". Seismologists anticipated a very large quake would strike in the same place as the 1923 Great Kantō earthquake — in the Sagami Trough, southwest of Tokyo. [231][232], Japanese funerals are normally elaborate Buddhist ceremonies that entail cremation. [337] Twenty thousand stranded visitors spent the night of 11–12 March inside Tokyo Disneyland. Date of the Earthquake. [376], In April 2015, authorities off the coast of Oregon discovered debris that is thought to be from a boat destroyed during the tsunami. [346], The Tōhoku Shinkansen line was worst hit, with JR East estimating that 1,100 sections of the line, varying from collapsed station roofs to bent power pylons, will need repairs. [75] The hypocentral region of this earthquake extended from offshore Iwate Prefecture to offshore Ibaraki Prefecture. [11][64] On 11 July 2016, the USGS further upgraded the earthquake to 9.1. [224] One elementary school in Ishinomaki, Miyagi, Okawa Elementary, lost 74 of 108 students and 10 of 13 teachers and staff.[225][226][227]. A spill of a couple of litres of radioactive water occurred at Onagawa. [335] In the hours after the earthquake, some train services were resumed. 3. Just a few years after the … [267] Several nuclear and conventional power plants went offline after the earthquake, reducing the Tokyo Electric Power Company's (TEPCO) total capacity by 21 GW. (2011, 19 March) "Japan Earthquake May Have Shifted Earth's Axis" – NPR online, PreventionWeb Great East Japan Earthquake 2011, Interactive Comparisons of Tōhoku Earthquake and Tsunami, Map to chronicle all known disasters in Japan from 416–2013, Foundation of the Covenant official and international dedicated to the victims of the tsunami, Nuclear power in Japan, section Seismicity, Fergana Valley (Uzbekistan, Kyrgyzstan and Tajikistan),ōhoku_earthquake_and_tsunami&oldid=993497028, 2011 natural disasters in the United States, Articles containing Japanese-language text, Articles with dead external links from June 2016, Short description is different from Wikidata, Wikipedia indefinitely move-protected pages, Wikipedia pages semi-protected against vandalism, Articles containing potentially dated statements from March 2016, All articles containing potentially dated statements, Articles with failed verification from February 2019, Creative Commons Attribution-ShareAlike License, Port of Hachinohe area – 8–9 metres (26–30 ft), Sendai section of Shiogama-Sendai port – 8 metres (26 ft). [318] Many radioactive hotspots were found outside the evacuation zone, including Tokyo. [39][74] The Pacific plate, which moves at a rate of 8 to 9 cm (3.1 to 3.5 in) per year, dips under Honshu's underlying plate, building large amounts of elastic energy. [237], Noted individual fatalities within Japan included 104-year-old Takashi Shimokawara, holder of the world athletics records in the men's shot put, discus throw and javelin throw for the over-100 age category. The heat build-up caused the generation of hydrogen gas. The tsunami height that had been initially predicted by the tsunami warning system was lower than the actual tsunami height; this error contributed to the delayed escape of some residents. [257] The Tōkaidō Shinkansen resumed limited service late in the day and was back to its normal schedule by the next day, while the Jōetsu and Nagano Shinkansen resumed services late on 12 March. The Japanese government's response to the earthquake, the efforts of Japanese citizens to help with recovery, and the disaster itself have inspired many works from Japanese creators. A team of scientists puts together the whole picture on what caused the extreme magnitude and slip during the 2011 magnitude-9 Tohoku earthquake, and overturns a long-held scientific law. At 0.5X animation speed, 1 second of animation = 1 hour in real time. [383] Television broadcasts of the press conferences of Prime Minister Naoto Kan and Chief Cabinet Secretary Yukio Edano included simultaneous JSL interpreters standing next to the Japanese flag on the same platform. [353] Internet services were largely unaffected in areas where basic infrastructure remained, despite the earthquake having damaged portions of several undersea cable systems landing in the affected regions; these systems were able to reroute around affected segments onto redundant links. The blackouts affected Tokyo, Kanagawa, Eastern Shizuoka, Yamanashi, Chiba, Ibaraki, Saitama, Tochigi, and Gunma prefectures. One of the first major foreshocks was a 7.2 Mw event on 9 March, approximately 40 km (25 mi) from the epicenter of the 11 March earthquake, with another three on the same day in excess of 6.0 Mw. [307][308][309] Officials from the Japanese Nuclear and Industrial Safety Agency reported that radiation levels inside the plant were up to 1,000 times normal levels,[310] and that radiation levels outside the plant were up to eight times normal levels. While the Japan Trenchwas known for creating large quakes, it had not b… [271] Voluntary reductions in electricity use by consumers in the Kanto area helped reduce the predicted frequency and duration of the blackouts. [184] Authorities in Wewak, East Sepik, Papua New Guinea evacuated 100 patients from the city's Boram Hospital before it was hit by the waves, causing an estimated US$4 million in damage. The reservoir at one concrete gravity dam suffered a small non-serious slope failure. The earthquake causes a … Most of these deaths occurred in Fukushima prefecture, where the prefecture government has suggested that they could be due to evacuations caused by the Fukushima Daiichi nuclear disaster. This motivated government researchers to look into other ways the earthquake may have had large scale effects on the planet. Approximately 30 homes or buildings were destroyed and 1,046 other buildings were damaged to varying degrees. More than 5,000 aftershocks hit Japan in the year after the earthquake, the largest a magnitude 7.9. [361], Matsushima Air Field of the Japan Self-Defense Force in Miyagi Prefecture was struck by the tsunami, flooding the base and resulting in damage to all 18 Mitsubishi F-2 fighter jets of the 21st Fighter Training Squadron. [76] The Japanese Meteorological Agency said that the earthquake may have ruptured the fault zone from Iwate to Ibaraki with a length of 500 km (310 mi) and a width of 200 km (120 mi). [285], An analyst estimates that consumption of various types of oil may increase by as much as 300,000 barrels (48,000 m3) per day (as well as LNG), as back-up power plants burning fossil fuels try to compensate for the loss of 11 GW of Japan's nuclear power capacity. The tsunami resulted in over 340,000 displaced people in the Tōhoku region, and shortages of food, water, shelter, medicine, and fuel for survivors. Equal joint 3: 2011 Tohoku earthquake. Subsequent analysis found that many Japanese nuclear plants, including Fukushima Daiichi, were not adequately protected against tsunamis. Stuart Biggs and Aaron Sheldrick (11 March 2011). [266], Tōhoku Electric Power was not able to provide the Kanto region with additional power because TEP's power plants were also damaged in the earthquake. [213], For the purpose of relief fund distribution, an "earthquake-related death" is defined as a case where the earthquake did not directly kill a person, but acted as a contributory factor that indirectly caused their death. The tsunami caused nuclear accidents, primarily the level 7 meltdowns at three reactors in the Fukushima Daiichi Nuclear Power Plant complex, and the associated evacuation zones affecting hundreds of thousands of residents. [197][198], The tsunami broke icebergs off the Sulzberger Ice Shelf in Antarctica, 13,000 km (8,100 mi) away. It was not as bad as the Chernobyl disaster, but worse than the Three Mile Island accident. In Ishinomaki alone, there were 17 trash collection sites 180 metres (590 ft) long and at least 4.5 metres (15 ft) high. [103], A month later, a major aftershock struck offshore on 7 April with a magnitude of 7.1 Mw. When the roads clear, experts will be dispatched to conduct further investigations. The 1964 Alaskan earthquake was a megathrust earthquake that began… [396], Researchers have also analysed the economic effects of this earthquake and have developed models of the nationwide propagation via interfirm supply networks of the shock that originated in the Tōhoku region.[397][398]. By Elisabeth Nadin Ph.D., University of Alaska Fairbanks The epicentre was located some 80 miles (130 km) east of the city of Sendai, Miyagi prefecture, and the focus occurred at a depth of 18.6 miles (about 30 … Some of the most widely reported reason for these deaths include "Physical and mental fatigue caused by life in temporary shelter", "Physical and mental fatigue caused by evacuation", "Delayed treatment due to an inoperative hospital", "Physical and mental fatigue caused by stress from the earthquake and tsunami". [190] Peru reported a wave of 1.5 m (4 ft 11 in) and more than 300 homes damaged. [387], Also, following the earthquake, for the first time in Japanese history, the Emperor addressed the nation in a pre-recorded television broadcast.[388][389]. [113], The number of aftershocks was associated with decreased health across Japan. [194][196], After a 2 m (6 ft 7 in) high surge hit Chile, it was reported that the reflection from those surges traveled back across the Pacific, causing a 30–60 cm (12–24 in) surge in Japan, 47–48 hours after the earthquake, according to observation from multiple tide stations [ja], including in Onahama, Owase, and Kushimoto. [40] The speed of the Earth's rotation increased, shortening the day by 1.8 microseconds due to the redistribution of Earth's mass. [312] This brought the total number of problematic reactors to six. [91] On 6 April the Japanese coast guard said that the quake shifted the seabed near the epicenter 24 metres (79 ft) and elevated the seabed off the coast of Miyagi Prefecture by 3 metres (9.8 ft). About 90 seconds after an earthquake, an additional report on the possibility of a tsunami will also be included in observation reports, in order to warn people before the JMA magnitude can be calculated. Kayapınar/DİYARBAKIR, Nursing home fire kills 11 people in Russia, 2 people killed, 2 others injured in Kabul explosion, 5 PKK members killed in northern Iraq, Turkey’s Defense Ministry says, 320 kilograms cannabis seized in southeastern Turkey, Macron awards highest French state medal to Egyptian dictator Sisi, Qatar Emir Sheikh Tamim welcomed by Erdoğan at the Presidential Complex, Erdoğan: Turkey has always acted patiently in the eastern Mediterranean, Erdoğan: Turkey is one of the rising centers of investment, production and trade. [101], The first sign international researchers had that the earthquake caused such a dramatic change in the Earth's rotation came from the United States Geological Survey which monitors Global Positioning Satellite (GPS) stations across the world. [342] Minami-Kesennuma Station on the Kesennuma Line was obliterated save for its platform;[343] 62 of 70 (31 of 35) JR East train lines suffered damage to some degree;[253] in the worst-hit areas, 23 stations on 7 lines were washed away, with damage or loss of track in 680 locations and the 30-km radius around the Fukushima Daiichi nuclear plant unable to be assessed. Cooling is needed to remove decay heat after a Generation II reactor has been shut down, and to maintain spent fuel pools. In the area near the trench, the coupling coefficient is high, which could act as the source of the large tsunami. Overall electricity consumption during July and August was also 14% less than in the previous year. A few cases of suicide are also included. "[53] Around 4.4 million households in northeastern Japan were left without electricity and 1.5 million without water.[54]. [301], The Energy Commissioner of the European Union Günther Oettinger addressed the European Parliament on 15 March, explaining that the nuclear disaster was an "apocalypse". The epicentre was 43 miles east of Tohoku at a depth of 20 miles. For the aftershock that occurred on 7 April, see, In the early days after the earthquake some other names were proposed and used. [129] The actual height prediction varied, the greatest being for Miyagi at 6 metres (20 ft) high. [98] Nearby Haneda Airport, built mostly on reclaimed land, was not damaged. The committee advised that future policy should be to protect against the highest possible tsunami. [55] By summer the Vice-minister for Economy, Trade and Industry, the head of the Nuclear and Industrial Safety Agency, and the head of the Agency for Natural Resources and Energy had all lost their jobs. A spill of "up to 3.8 litres" of radioactive water also occurred at Onagawa following the aftershock. [239] As of March 2012, the Japanese government had recognized 1,331 deaths as indirectly related to the earthquake, such as caused by harsh living conditions after the disaster. [351] This led to near-paralysis within the capital, with long lines at train stations and many people unable to come to work or get home. A 5.5 magnitude earthquake hit off Tohoku Region, Japan. The Survey team had several GPS monitors located near the scene of the earthquake. [296] On 14 March it was reported that a cooling system pump for this reactor had stopped working;[330] however, the Japan Atomic Power Company stated that there was a second operational pump sustaining the cooling systems, but that two of three diesel generators used to power the cooling system were out of order. [377], According to Japan's foreign ministry, 116 countries and 28 international organizations offered assistance. Aftershocks continued, many exceeding magnitude-7.0. [247] Three hundred hospitals with 20 beds or more in Tōhoku were damaged by the disaster, with 11 being completely destroyed. The source area of this earthquake has a relatively high coupling coefficient surrounded by areas of relatively low coupling coefficients in the west, north, and south. [140] At least 101 designated tsunami evacuation sites were hit by the wave. [354][355] Within Japan, only a few websites were initially unreachable. Its epicenter was underwater, 66 km (41 mi) off the coast of Sendai. [189], Along the Pacific Coast of Mexico and South America, tsunami surges were reported, but in most places caused little or no damage. [105][106][107], Four days later on 11 April, another magnitude 7.1 Mw aftershock struck Fukushima, causing additional damage and killing a total of three people. [10], The degree and extent of damage caused by the earthquake and resulting tsunami were enormous, with most of the damage being caused by the tsunami. Victims aged 60 or older accounted for 65.2% of the deaths, with 24% of total victims being in their 70s. [74] A quake of this magnitude usually has a rupture length of at least 500 km (310 mi) and generally requires a long, relatively straight fault surface. [375], The aftermath of the twin disasters also left Japan's coastal cities and towns with nearly 25 million tons of debris. An official in the city's government trash disposal department estimated that it would take three years to empty these sites. (The early estimate of magnitude 8.9 was later revised upward.) The report also stated that the quake had caused several major landslides on the seabed in the affected area. [143], Among the factors in the high death toll was the unexpectedly large water surge. There were also huge numbers of large sized aftershocks, as big as magnitude 6. Thousands of lives were lost and entire towns were devastated. [244][245] Although Japan has invested the equivalent of billions of dollars on anti-tsunami seawalls which line at least 40% of its 34,751 km (21,593 mi) coastline and stand up to 12 m (39 ft) high, the tsunami simply washed over the top of some seawalls, collapsing some in the process. Here are some of the amazing facts about the Japan earthquake and tsunami. Of those who didn't heed the warning, 49% were hit by the water. After the 2011 disaster the UNISDR, United Nations International Strategy for Disaster Reduction, held its World Conference on Disaster Risk Reduction in Tohoku in March 2015, which produced the Sendai Framework document to guide efforts by international development agencies to act before disasters instead of reacting to them after the fact. The earthquake was the fifth-strongest since 1900, and the seventh-largest in recorded history. [178][179] In California and Oregon, up to 2.4 m-high (7.9 ft) tsunami waves hit some areas, damaging docks and harbors and causing over US$10 million in damage. [69] The seismic moment (M0), which represents a physical size for the event, was calculated by the USGS at 3.9×1022 joules,[85] slightly less than the 2004 Indian Ocean quake. (ILKHA). The early 1700s were a busy time seismically. Stone monuments at the UNESCO World Heritage Site: Shrines and Temples of Nikkō were toppled. [333][334] All railway services were suspended in Tokyo, with an estimated 20,000 people stranded at major stations across the city. [58] The World Bank's estimated economic cost was US$235 billion, making it the costliest natural disaster in history. [170] It was also estimated that the tsunami reached heights of up to 40.5 metres (133 ft) in Miyako in Tōhoku's Iwate Prefecture. [172], Delayed evacuations in response to the warnings had a number of causes. Because the plate boundary and subduction zone in the area of the Honshu rupture is not very straight, it is unusual for the magnitude of its earthquake to exceed 8.5 Mw; the magnitude of this earthquake was a surprise to some seismologists. [175][176] Russia evacuated 11,000 residents from coastal areas of the Kuril Islands. [80], Most of the foreshocks are interplate earthquakes with thrust-type focal mechanisms.
