2011 Japan earthquake

It was also being called the 2011 Great Eastern Japan earthquake. As well it was called as Great Sendai earthquake. Earthquake had the power of 9.0 magnitude. It was the fifth biggest earthquake in the world and the worst in Japan history. The 2011 Japan earthquake was experienced within Japan mainland, Honshu.

It was a large earthquake after the last earthquake took place in Kobe or to be called the Great Hanshin earthquake in 1995 causing thousands fatalities. This Japan earthquake caused more than 5.000 lives to die because of the earthquake and hazard caused by earthquake such as tsunami. All of the destruction was estimated around $310 billion dollars.

Hazard Caused by Earthquake

The tsunami has been hitting as far as 6 miles from the shoreline. Tsunami was triggered because the earthquake occurred on the shore east of Japan. The height of tsunami was 133 feet high to sweep the Sendai city area.

It was the second most hazardous tsunami since the tsunami caused by 9.1 earthquake in Indonesia that caused about 10 billion dollars worth of destruction and brought about around 220.000 casualties in 2004.

The explosion of the nuclear power reactor was regarded as the most hazardous nuclear disaster since nuclear crisis in Chernobyl, Ukraine. As a result, four of Fukushima nuclear plants were leaked and radioactive substance was released that threaten the Japanese people. Around 40.000 people were evacuated as a result of the leak of the nuclear reactor.

The total of 90.000 had moved into a temporary place. It was because the damage of the houses because of the tsunami as well as the threat of the dangerous radioactive substance from the leakage of nuclear reactor.

Where was The Focus and The Epicenter Of The 2011 Great Eastern Japan Earthquake?

The focus of the earthquake was estimated around 20 miles (30 kilometers) under the sea ground of Pacific. It happened in 14:46 Japan time on Friday, 11 March 2011.  The earthquake had hit on the epicenter around 43 miles to the east from Tohoku province.

The epicenter was around 43 miles (70 kilometers) eastern side of Sendai. As a result, the Honshu Island was actually being moved to the east in about 8 feet. As well, the earth axis has moved for about 4 inches from its previous axis point.

What were the Causes of The 2011 Great Eastern Japan Earthquake?

The Japan had been located in the most dangerous place with regards to earthquake and earthquake hazard such as tsunami. Tsunami was originated from Japanese language. They lived on the boundary of significant tectonic plates that shifted and locked which might be unlocked to produce a powerful quake and giant tsunami.

The earthquake was actually caused by the thrust fault that was triggered in the subduction zone. It was caused by tension built up over decades by two tectonic plates which were North America plate as well as Pacific plate. Thrust fault was the motion regarding tectonic plates that happened in subduction zone.

The tsunami was regarded as the worst in 2011 Japan Earthquake history since year of 1900 and caused by the thrust fault in the subduction zone. The subduction zone was considered the area of thrust fault regarding tectonic plates over period of times pushed beneath another plate and caused a serious and intense earthquake. In Japan case, it triggered a massive tsunami that brought the worst damage for Japan in the history. The 9 magnitude also was recorded as one the fifth largest earthquakes in the world history.
