The 2011 Earthquake and Tsunami, in Tōhoku Japan had a magnitude of 9.0. It was the fifth most powerful earthquake in the world since 1900 and the biggest ever recorded Earthquake to hit japan. This was a undersea megathrust earthquake off the coast of Japan that occurred at 2:46 on Friday 11 March 2011. The epicentre was approximately 70 km East of the Oshika Peninsula of Tōhoku and the hypocenter at an underwater depth of approximately 30 km. The earthquake is also know as the Great East Japan Earthquake in Japan.
The earthquake triggered huge tsunami waves that reached heights of up to 40.5 metres in Miyako, Tōhoku. The earthquake moved Honshu (the main island of Japan) 2.4 m East and shifted the Earth on its axis, between 10 cm and 25 cm and made sound waves that were detected by the GOCE satellite.
It was caused by movement between the Pacific and North American plates. An huge amount of energy was released by a sudden upward movement, this caused the tsunami by a enormous sea water displacement.

On 10 February 2014, it was confirmed that there was 15,885 dead, 6,148 injured, and 2,623 people missing across twenty Territories. 127,290 buildings totally collapsed, with a further 272,788 buildings 'half collapsed', and another 747,989 buildings damaged. 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. The Japanese Prime Minister Naoto Kan said, "In the 65 years after the end of World War II, this is the toughest and the most difficult crisis for Japan."
The tsunami caused nuclear accidents, mainly the level 7 (major accident) meltdowns (severe nuclear reactor accident) at three reactors in the Fukushima Daiichi Nuclear Power Plant. Many electrical generators were taken down, and at least three nuclear reactors suffered explosions due to hydrogen gas that had built up, after cooling system failure. Residents within a 20 km of the Fukushima Daiichi Nuclear Power Plant and a 10 km of the Fukushima Daini Nuclear Power Plant were evacuated. Around 4.4 million households in Northeastern Japan were left without electricity and 1.5 million without water.
