FUKUSHIMA

The 11th March of 2011 there was a big earthquake in Japan. Its name is Fukushima.Before the earthquake, two days before, the 9th March, there were little earthquakes, but nothing compared to what happened at 14:46 (local hour). The epicenter was situated in the Pacific Ocean, 130km far from Honshu and 373km from Tokyo. A minute before the earthquake, all the seismographs warned the scientists that there was going to be a earthquake. It was an earthquake of 9,2mw (moment magnitude). It released the same energy we need to give electricity to Los Angeles a whole year.The Pacific plate moved to the West in respect to Nord-America at 33mm/year. A part of the Pacific plate went under the Ojostk plate during the earthquake.

Fukushima

An earthquake is produced by the energy released by the crash of two or more tectonic plates. A tectonic plate is a rigid part of the lithosphere which moves over the asthenosphere. The lithosphere is divided in big and little plates, the little ones are named microplates. The plates’ tectonics is a theory that talks about the structure and the dynamic of the terrestrial surface. With this theory all the geological and geophysical movements had already an explanation; the realizing of Earth’s heat

Earthquakes

The Fukushima earthquake was caused because of two plates:- THE PACIFIC PLATE:The Pacific Plate is the oldest plate in the Earth, and it limits with many plates. As it is really wide in the Asiatic and Australian coasts pieces of croast crush and form the Fire Belt.- NORD-AMERICAN PLATE:It’s a mixed plate, which means it has continental and oceanic crosts.

The tsunamis are giant waves that get to the coast without any warnings. Tsunamis are made because of tremors or volcanos that move underwater sand. This movement is named “Earth tremor”.

The earthquake and the tsunami made important changes in the Japanese society, it affected the electricity, the telecommunications, the dams and the water supplies, the nuclear power centrals' reactors and the transports' infraestructures.After the tsunami, the Japanese National Police Agency confirmed that there were 15.845 deaths, 3.380 missing people and 5.893 hurt people. A study discovered that 13.135 (92,5%) drowned.
