![]() Fukushima Daiichi units 4, 5&6 were not operating at the time, but were affected. The operating units which shut down were Tokyo Electric Power Company's (Tepco's) Fukushima Daiichi 1, 2, 3, and Fukushima Daini 1, 2, 3, 4, Tohoku's Onagawa 1, 2, 3, and Japco's Tokai, total 9377 MWe net. ![]() Subsequent inspection showed no significant damage to any from the earthquake. The tsunami inundated about 560 km 2 and resulted in a human death toll of about 19,500 and much damage to coastal ports and towns, with over a million buildings destroyed or partly collapsed.Įleven reactors at four nuclear power plants in the region were operating at the time and all shut down automatically when the earthquake hit. Japan moved a few metres east and the local coastline subsided half a metre. An area of the seafloor extending 650 km north-south moved typically 10-20 metres horizontally. The earthquake was centred 130 km offshore the city of Sendai in Miyagi prefecture on the eastern coast of Honshu Island (the main part of Japan), and was a rare and complex double quake giving a severe duration of about 3 minutes. The Great East Japan Earthquake of magnitude 9.0 at 2.46 pm on Friday 11 March 2011 did considerable damage in the region, and the large tsunami it created caused very much more. Disaster-related deaths are in addition to the about 19,500 that were killed by the earthquake or tsunami.
