[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 distance of the coast of Japan from the Epicentre. [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. 4. [224] One elementary school in Ishinomaki, Miyagi, Okawa Elementary, lost 74 of 108 students and 10 of 13 teachers and staff.[225][226][227]. The large number of views made the video one of the most popular examples of sonification on the web. Although the tsunami affected many of these places, the heights of the waves were minor. Cabinet Office Disaster Management, Government of Japan (2015). Approximately 30 homes or buildings were destroyed and 1,046 other buildings were damaged to varying degrees. [305] In February 2019, there were 42 operable reactors in Japan. [211], Of the 13,135 fatalities recovered by 11 April 2011, 12,143 or 92.5% died by drowning. [12][32][33] 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. [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. [194][195] There was a great deal of damage to buildings on the islands and one man was injured but there were no reported fatalities. Indian Ocean Earthquake, 26 December 2004. [50], A report by the National Police Agency of Japan on 10 September 2018 listed 121,778 buildings as "total collapsed", with a further 280,926 buildings "half collapsed", and another 699,180 buildings "partially damaged". The amplitude of the seismic wave is measured using the JMA magnitude scale, which is similar to Richter magnitude scale. [300], A report by the IAEA in 2012 found that the Onagawa Nuclear Power Plant, the closest nuclear plant to the epicenter of the 2011 earthquake and tsunami, had remained largely undamaged. [324] The plant was shut down as a precaution. [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. [365], JAXA (Japan Aerospace Exploration Agency) evacuated the Tsukuba Space Center in Tsukuba, Ibaraki. [121], An upthrust of 6 to 8 metres (20 to 26 ft) along a 180 kilometres (110 mi) wide seabed at 60 kilometres (37 mi) offshore from the east coast of Tōhoku[122] resulted in a major tsunami that brought destruction along the Pacific coastline of Japan's northern islands. Japan specifically requested assistance from teams from Australia, New Zealand, South Korea, and the United States. To prevent under-reporting of tsunami heights, early quantitative observation data that are smaller than the expected amplitude will be overridden and the public will instead be told that the situation is under observation. [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 damaged buildings included 29,500 structures in Miyagi Prefecture, 12,500 in Iwate Prefecture and 2,400 in Fukushima Prefecture. [391][392] The Headquarters For Earthquake Research Promotion set up by Japanese government then reassessed the long term risk of trench-type earthquakes around Japan, and it was announced in November 2011 that research on the 869 Sanriku earthquake indicated that a similar earthquake with a magnitude of Mw 8.4–9.0 would take place off the Pacific coast of northeastern Japan, on average, every 600 years. Without ventilation, gas accumulated within the reactor containment structures and eventually exploded. [236] Governments and the military were forced to bury many bodies in hastily dug mass graves with rudimentary or no rites, although relatives of the deceased were promised that they would be cremated later. [401], 2011 magnitude 9.0 - 9.1 earthquake off the coast of Japan, "2011 Miyagi earthquake" redirects here. [11][64] On 11 July 2016, the USGS further upgraded the earthquake to 9.1. [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. 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. (201 1) suggest that The earthquake has not prompted any tsunami advisories. Services on the Tōhoku Shinkansen partially resumed only in Kantō area on 15 March, with one round-trip service per hour between Tokyo and Nasu-Shiobara,[347] and Tōhoku area service partially resumed on 22 March between Morioka and Shin-Aomori. [254] Most were restored to operating condition by 18 April 2012. [327][328] Tōhoku Electric Power Co. stated this may have been due to radiation from the Fukushima Daiichi nuclear accidents but was not from the Onagawa plant itself. Furthermore, shortly after the earthquake, some wave meters reported a fluctuation of "20 centimetres (7.9 in)", and this value was broadcast throughout the mass media and the warning system, which caused some residents to underestimate the danger of their situation and even delayed or suspended their evacuation. Another cause of delayed evacuations was the release of the second update on the tsunami warning long after the earthquake (28 minutes, according to observations); by that time, power failures and similar circumstances reportedly prevented the update from reaching some residents. A massive earthquake of magnitude of 9.0 occurred Friday 11 March, off the Pacific coast of the northeastern part of the Japanese main land (Tohoku Region), causing devastating damages. [304], In 2013, only two nuclear reactors in Japan had been restarted since the 2011 shutdowns. The rolling blackouts brought on by the crises at the nuclear power plants in Fukushima had a profound effect on the rail networks around Tokyo starting on 14 March. From the averaged coupling coefficient of 0.5–0.8 in the source area and the seismic moment, it was estimated that the slip deficit of this earthquake was accumulated over a period of 260–880 years, which is consistent with the recurrence interval of such great earthquakes estimated from the tsunami deposit data. [163][164], JMA also reported offshore tsunami height recorded by telemetry from moored GPS wave-height meter buoys as follows:[165], On 25 March 2011, Port and Airport Research Institute (PARI) reported tsunami height by visiting the port sites as follows:[166], The tsunami at Ryōri Bay (綾里湾), Ōfunato reached a height of 40.1 metres (132 ft) (run-up elevation). 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. "What Have Religious Groups Done After 3.11? However, the estimated intensities were smaller than the actual ones in some places, especially in Kanto, Koshinetsu, and Northern Tōhoku regions where the populace warning did not trigger. "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. There was a magnitude 7.2 earthquake on the 9th of March, 2 days before the 8.9-9.0 magnitude earthquake of the 11th. [114], One minute before the earthquake was felt in Tokyo, the Earthquake Early Warning system, which includes more than 1,000 seismometers in Japan, sent out warnings of impending strong shaking to millions. Initially, the earthquake caused sinking of part of Honshu's Pacific coast by up to roughly a metre, but after about three years, the coast rose back and kept on rising to exceed its original height. The violent movement of the Earth's tectonic plates … The loss of electrical power halted cooling systems, causing heat to build up. [372] Information on the condition of collections held by museums, libraries and archives is still incomplete. It was not as bad as the Chernobyl disaster, but worse than the Three Mile Island accident. As a result, the communities in question are now more susceptible to flooding during high tides. İlke Haber Ajansı Basın Yayın Sanayi Ticaret A.Ş. [384], According to Jake Adelstein, most Japanese media accepted and parroted the misinformation put out by the Japanese government and TEPCO about the unfolding Fukushima nuclear crisis. [131], The earthquake took place at 14:46 JST (UTC 05:46) around 67 kilometres (42 mi) from the nearest point on Japan's coastline, and initial estimates indicated the tsunami would have taken 10 to 30 minutes to reach the areas first affected, and then areas farther north and south based on the geography of the coastline. [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. This is the fourth largest earthquake in the world and the largest in Japan since instrumental recordings began in 1900. [377], According to Japan's foreign ministry, 116 countries and 28 international organizations offered assistance. [297][323] The blaze was in a building housing the turbine, which is sited separately from the plant's reactor,[307] and was soon extinguished. The Japanese government had tracked plate movements since 1976 in preparation for the so-called Tokai earthquake, predicted to take place in that region. of dead or missing tops 22,000; bodies buried in rare measure", "Gradual Restoration of Infrastructure Continues at Disaster Areas", "asahi.com(朝日新聞社):計画停電で影響が出る主な鉄道(午前7時現在) – 社会", "A Look at the Japanese City Closest to the Quake", "In Japan, Many Undersea Cables Are Damaged: Broadband News and Analysis", "Japan's phone networks remain severely disrupted", "AT&T, Sprint & Verizon Offer Free Calls & Texts to Japan from U.S. [UPDATED]", "T-Mobile USA Waives Call Charges to Japan and Wi-Fi Calling and Text Messaging Charges to and From Japan", "netTALK Extends Free Calling to Japan Through April", "Deutsche Telekom: Konzern erleichtert Kommunikation nach Japan", "Mitsubishi Heavy Industries bids goodbye to F2 aircraft", "Tsunami and earthquake in Japan: latest pictures of the damage", "Air SDF to scrap 12 fighters, citing tsunami damage", "Quake forces closure of Japanese space center", "asahi.com(朝日新聞社):茨城の宇宙機構施設が損傷 「きぼう」一部管制できず – サイエンス", "Damages to Cultural Properties in "the Great East Japan Earthquake, "An Interim Report on the Situation of Cultural Heritage in Japan after the Tōhoku district -off the Pacific Ocean Earthquake (or Tōhoku Earthquake)", "Piece of Ship from Japan's 2011 Tsunami Surfaces in Oregon", "Japan requests foreign rescue teams, UN says", "Ustream Asia、民放TV各局の東北地方太平洋沖地震報道番組を同時配jmjffr -INTERNET Watch", Listen to Live Coverage from Japan In English from YokosoNews, "Local broadcasters remain calm during the quake crisis,", "Foreign media take flak for fanning fears,", "In Japan, disaster coverage is measured, not breathless,", "First interpreting at government press conference on disaster,", "Japan Relief Headquarters for Persons with Disabilities Petition for Support and Accommodation Following Earthquake,", "New Komeito post-quake initiatives being adopted,", "Japan's PM set to visit crippled nuclear plant,", "New Komeito post-quake initiatives being adopted | Komei News (March 20, 2011)", What 2011 means for Japan in 2012 and beyond, "Sonification of Tohoku Earthquake / Sendai Coast, Japan, 2011/03/11", "Somber Japan emperor makes unprecedented address to nation", "Japan's Emperor Akihito expresses 'deep concern' over Fukushima nuclear plant crisis", "Japan: The 'Big One' hit, but not where they thought it would", "Japan Quake Epicenter Was in Unexpected Location", "Japan earthquake shifted Earth on its axis", "Prompt gravity signal induced by the 2011 Tohoku-Oki earthquake", "How do supply chain networks affect the resilience of firms to natural disasters? [214] These indirect casualties have already resulted in more deaths than the number of people killed directly by earthquake and tsunami within the Fukushima prefecture. The 2011 Tōhoku earthquake and tsunami was a 9.0-magnitude earthquake followed by tsunami waves. Here are some of the amazing facts about the Japan earthquake and tsunami. Good news, bad news It was measured at 8.4 on the JMA seismic intensity scale The earthquake happened 130 kilometres (81 mi) off Sendai, Miyagi Prefecture, on the east coast of the Tōhoku of Japan, on March 11, 2011 at 05:46:23 UTC.It was at a depth of 24.4 km (15.2 miles). One man was killed in Jayapura, Papua, Indonesia after being swept out to sea. [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. Date: Mar 27th, 1964. The earthquake causes a … A 5.5 magnitude earthquake hit off Tohoku Region, Japan. The north eastern ports of Hachinohe, Sendai, Ishinomaki and Onahama were destroyed, while the Port of Chiba (which serves the hydrocarbon industry) and Japan's ninth-largest container port at Kashima were also affected, though less severely. [190] The surge in Chile was large enough to damage more than 200 houses,[191] with waves of up to 3 m (9.8 ft). The Geological Society of London is the UK's learned and professional body for Earth scientists, with over 12,000 members worldwide. 6 days. There may be a need to replace the contaminated soil. Equal joint 3: 2011 Tohoku earthquake. Seismic stations in Iwate, Gunma, Saitama and Chiba Prefecture measured a lower 6, recording an upper 5 in Tokyo. 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. The economic impact included both immediate problems, with industrial production suspended in many factories, and the longer term issue of the cost of rebuilding which has been estimated at ¥10 trillion ($122 billion). [108][109], On 7 December 2012 a large aftershock of magnitude 7.3 Mw caused a minor tsunami, and again on 26 October 2013 a small tsunami was recorded after a 7.1 Mw aftershock. [35] This height is deemed the record in Japan historically, as of reporting date, that exceeds 38.2 metres (125 ft) from the 1896 Meiji-Sanriku earthquake. 3. Its epicenter was underwater, 66 km (41 mi) off the coast of Sendai. meeting of CCEP, Coordinating Committee for Earthquake Prediction, "中日新聞:災害義援金受け付け 東日本大震災:中日新聞からのお知らせ(CHUNICHI Web)", "東日本巨大地震 震災掲示板 : 特集 : YOMIURI ONLINE(読売新聞)", "番組表 – TOKYO FM 80.0 MHz – 80.Love FM RADIO STATION", USGS Updates Magnitude of Japan's 2011 Tōhoku Earthquake to 9.03, "Japan earthquake and tsunami of 2011 | Facts & Death Toll", "Tsunami, earthquake, nuclear crisis – now Japan faces power cuts", "Japan quake – 7th largest in recorded history", "March 11th tsunami a record 40.5 metres high NHK", "Japan earthquake: Tsunami hits north-east", "Quake Moves Japan Closer to U.S. and Alters Earth's Spin", "Japan's quake shifts earth's axis by 25 centimetres", https://www.npa.go.jp/news/other/earthquake2011/pdf/higaijokyo_e.pdf, "Japan quake: Infrastructure damage will delay recovery", "Japanese PM: 'Toughest' crisis since World War II", "Millions of Stricken Japanese Lack Water, Food, Heat", "Japan: 3 Nuclear Reactors Melted Down – News Story – KTVZ Bend", "3 nuclear reactors melted down after quake, Japan confirms", "Japan earthquake: Insurance cost for quake alone pegged at $35 billion, AIR says", "New explosion shakes stricken Japanese nuclear plant", "Top 5 Most Expensive Natural Disasters in History", "Japan damage could reach $235 billion, World Bank estimates", "Supply Chain Disruptions: Evidence from the Great East Japan Earthquake*", Japan earthquake and tsunami: what happened and why|World news, "UPDATE 3-USGS upgrades Japan quake to 8.9 magnitude", "USGS Updates Magnitude of Japan's 2011 Tōhoku Earthquake to 9.0", "地震情報 – 2011年3月10日 15時6分 – 日本気象協会 tenki.jp", "地震情報 – 2011年3月11日 15時15分 – 日本気象協会 tenki.jp", "Earthquake strikes near Japan's Fukushima nuclear plant; no reports of damage", "Challenges of anticipating the 2011 Tohoku earthquake and tsunami using coastal geology", "The future of tsunami research following the 2011 Tōhoku-oki event", "The 869 Jōgan tsunami deposit and recurrence interval of large-scale tsunami on the Pacific coast of northeast Japan", "newspaper: Japan earthquake and tsunami: what happened and why", "Size of Japan's quake surprises seismologists", "時事ドットコム:M8.8、死者300人超=行方不明540人以上−大津波10m・宮城で震度7", "asahi.com(朝日新聞社):地殻破壊3連鎖、計6分 専門家、余震拡大に警鐘 – 東日本大震災", "Japan Meteorological Agency | Earthquake Information", "Information message about destructive earthquake near the eastern coast of Honshu Island of Japana on March 11, 2011", "The 2011 Japan Earthquake, Tsunami and Nuclear Disaster", "Preliminary report of the 2011 off the Pacific coast of Tōhoku Earthquake", "Asian Disaster Reduction Center (ADRC) Information Sharing on Disaster Reduction", "March 11, 2011 M9.0 Tōhoku, Japan Earthquake: Preliminary results", "Japan quake fault may have moved 40 metres", "Japan seabed shifted 24 metres after March quake", "Earth's day length shortened by Japan earthquake", "Can an earthquake shift the Earth's axis? [39] A 400-kilometre (250 mi) stretch of coastline dropped vertically by 0.6 metres (2 ft 0 in), allowing the tsunami to travel farther and faster onto land. 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. Stuart Biggs and Aaron Sheldrick (11 March 2011). The blackouts affected Tokyo, Kanagawa, Eastern Shizuoka, Yamanashi, Chiba, Ibaraki, Saitama, Tochigi, and Gunma prefectures. Before the earthquake/tsunami Tohoku was a very pretty place, with lots of flowers, and mountains. 466 Sk. [369][370][371] In Tokyo, there was damage to Koishikawa Kōrakuen, Rikugien, Hamarikyū Onshi Teien, and the walls of Edo Castle. KGW estimates that more than 1 million tons of debris still remain in the Pacific Ocean. [247] Three hundred hospitals with 20 beds or more in Tōhoku were damaged by the disaster, with 11 being completely destroyed. These include Sendai #4, New-Sendai #1 and #2, Haranomachi #1 and #2, Hirono #2 and #4 and Hitachinaka #1. The system automatically stopped all high-speed trains, which minimized the damage. [241], The tsunami was reported to have caused several deaths outside Japan. [311] Later, a state of emergency was also declared at the Fukushima Daini nuclear power plant about 11 km (6.8 mi) south. In comparison to the 1995 Great Hanshin earthquake, the East Japan earthquake brought serious damage to an extremely wide range. Onagawa Nuclear Power Plant lost three of its four external power lines and temporarily lost cooling function in its spent fuel pools for "20 to 80 minutes". [36], The earthquake moved Honshu (the main island of Japan) 2.4 m (8 ft) east, shifted the Earth on its axis by estimates of between 10 cm (4 in) and 25 cm (10 in),[38][39][40] increased earth's rotational speed by 1.8 µs per day,[41] and generated infrasound waves detected in perturbations of the low-orbiting Gravity Field and Steady-State Ocean Circulation Explorer satellite. The map and text below show the following details : a) the observed Seismic Intensity (1 and above) and its location and region, b) the date and time of the earthquake, and c) its epicenter and magnitude. [40] The speed of the Earth's rotation increased, shortening the day by 1.8 microseconds due to the redistribution of Earth's mass. Japan's National Research Institute for Earth Science and Disaster Prevention (NIED) calculated a peak ground acceleration of 2.99 g (29.33 m/s2). [332], Japan's transport network suffered severe disruptions. It could take months or years to learn how damaging the release of dangerous isotopes has been to human health and food supplies, and to the surrounding countryside. Yan Y. Kagan, & David D. Jackson Published May 2013, SCEC Contribution #1670 We consider three questions related to the 2011 Tohoku mega-earthquake: (1) Why was the event size so grossly under-estimated by Japan's national hazard map? [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]. maximum magnitude size for Tohoku area (around 7.7) was proposed in the official hazard map (Geller, 2011; Stein et al. [390][391] The Japanese government had tracked plate movements since 1976 in preparation for the so-called Tokai earthquake, predicted to take place in that region. [318] Many radioactive hotspots were found outside the evacuation zone, including Tokyo. 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. More than 5,000 aftershocks hit Japan in the year after the earthquake, the largest a magnitude 7.9. The seismic moment of this earthquake accounts for about 93% of the estimated cumulative moment from 1926 to March 2011. [123][124][125] Chile's Pacific coast, one of the furthest from Japan at about 17,000 kilometres (11,000 mi) away, was struck by waves 2 metres (6.6 ft) high,[126][127][128] compared with an estimated wave height of 38.9 metres (128 ft) at Omoe peninsula, Miyako city, Japan. Another moment conservation method, applied at a point on a major fault or plate boundary, also suggests that magnitude 9 events are required to explain observed displacement rates at least for the Tohoku area. [187] Some other South Pacific countries, including Tonga and New Zealand, and US territories American Samoa and Guam, experienced larger-than-normal waves, but did not report any major damage. [98] Nearby Haneda Airport, built mostly on reclaimed land, was not damaged. [296] Higashidōri, also on the northeast coast, was already shut down for a periodic inspection. [219] 236 children were orphaned in the prefectures of Iwate, Miyagi and Fukushima by the disaster;[220][221] 1,580 children lost either one or both parents,[222] 846 in Miyagi, 572 in Iwate, and 162 in Fukushima. Magnitude: 9.2. The earthquake lasted 6 minutes … An 8.4 magnitude earthquake on March 2, 1933 triggered a tsunami which caused widespread damage to towns on the Sanriku coast of the Tohoku region of Honshu. [303], Later analysis indicated three reactors at Fukushima I (Units 1, 2, and 3) had suffered meltdowns and continued to leak coolant water. Time it took to repair a motorway damaged by the tsunami. The committee advised that future policy should be to protect against the highest possible tsunami. The plant's 14-metre-high (46 ft) seawall successfully withstood the tsunami. [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. [368], 754 cultural properties were damaged across nineteen prefectures, including five National Treasures (at Zuigan-ji, Ōsaki Hachiman-gū, Shiramizu Amidadō, and Seihaku-ji); 160 Important Cultural Properties (including at Sendai Tōshō-gū, the Kōdōkan, and Entsū-in, with its western decorative motifs); one hundred and forty-four Monuments of Japan (including Matsushima, Takata-matsubara, Yūbikan, and the Site of Tagajō); six Groups of Traditional Buildings; and four Important Tangible Folk Cultural Properties. [252] All 15 ports reopened to limited ship traffic by 29 March 2011. [257] Eleven airliners bound for Narita were diverted to nearby Yokota Air Base. [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. It was the most powerful earthquake ever recorded in Japan, and the fourth most powerful earthquake in the world since modern record-keeping began in 1900. A spill of a couple of litres of radioactive water occurred at Onagawa. Ustream Asia broadcast live feeds of NHK, Tokyo Broadcasting System, Nippon TV, Fuji TV, TV Asahi, TV Tokyo, Tokyo MX, TV Kanagawa, and CNN on the Internet starting on 12 March 2011. [79] Other major earthquakes with tsunamis struck the Sanriku Coast region in 1896 and in 1933. Overall electricity consumption during July and August was also 14% less than in the previous year. The 2011 Tōhoku earthquake and tsunami has been assigned GLIDE identifier EQ-2011-000028-JPN by the Asian Disaster Reduction Center. 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. In Russia, the main shock could be felt in Yuzhno-Sakhalinsk (MSK 4) and Kurilsk (MSK 4). [159] The tsunami washed away the sole bridge to Miyatojima, Miyagi, isolating the island's 900 residents. [93], The Earth's axis shifted by estimates of between 10 cm (4 in) and 25 cm (10 in). The surface energy of the seismic waves from the earthquake was calculated to be 1.9×1017 joules,[84] which is nearly double that of the 9.1 Mw 2004 Indian Ocean earthquake and tsunami that killed 230,000 people. Victims aged 60 or older accounted for 65.2% of the deaths, with 24% of total victims being in their 70s. [113], The number of aftershocks was associated with decreased health across Japan. [38][94] The earthquake also generated infrasound waves detected by perturbations in the orbit of the GOCE satellite, which thus serendipitously became the first seismograph in orbit. Sumitomo Metal Industries could produce up to 500 MW, JFE Steel 400 MW, and Nippon Steel 500 MW of electric power[275] Auto and auto parts makers in Kanto and Tōhoku agreed in May 2011 to operate their factories on Saturdays and Sundays and close on Thursdays and Fridays to help alleviate electricity shortages during the summer of 2011. Evidence from the Great East Japan Earthquake", "Energy and resilience: The effects of endogenous interdependencies on trade network formation across space among major Japanese firms", Fault that Caused Japan's 2011 Earthquake is Thin and Slippery. [37] Residents of Sendai had only eight to ten minutes of warning, and more than a hundred evacuation sites were washed away.
