What would you like to do?
Japan is situated on four tectonic plates. The earthquake was the result of movement between two of the plates. The Pacific Plate and the Eurasian Plate.

The Earth is covered with tectonic "plates", partial shells of rock. As heat is distributed from the Earth's core, it moves the plates around very slowly. But the plates stick… together around the edges, and as forces build up, the plates jerk or lurch across the Earth's mantle. We call this an "earthquake". The Japan plate touches the Pacific plate, and over the last 100 years or so, considerable stress built up along the boundaries. On March 11, 2011, much of the stress was relieved as the Pacific plate rode underneath the Japan plate. The movement of the Earth was significant, but the jolt caused a movement in the ocean, called a "tsunami". The tsunami is what caused most of the damage and deaths. As of March 20, 2011, the official death toll is over 8,000, but there are about 15,000 people still missing. Most areas of the Earth are subject to occasional earthquakes, especially around the edges of the Pacific plate. Because of the frequency of earthquakes and volcanoes, this is sometimes called the "Ring of Fire". Within the past year, in addition to the March 11 quake, major earthquakes have occurred in New Zealand and Chile.
The magnitude 9.0 earthquake that hit Japan in 2011 occurred at 14:46 JST (05:46 UTC) on Friday 11 March 2011. You can see what time that was in your area in the r…elated links below.
The Northeastern coast of Japan . Note: Their Nuclear Power Plants released chemicals into the air because of the earthquake. VERY VERY BAD!!!! (May affect LA)
The epicenter of the Japan Earthquake which occurred on 11 March was 125 kilometers away from Japan North Eastern Coast. The Focus Point was 24 kilometers deep into the ground….
Tectonic plates shifted, creating the earthquake.
Because the Pacific Plate is moving to the northwest, and Japan, New Zealand, Alaska, and California are all located on the boundary of that plate. Haiti and Chili are on the …boundaries of other plates, and when one moves, it effects the one next to it. My bet is on Anchorage Alaska for the next big quake. Another Answer: It's because on plate banged into another one which made it go down and then it flicked up causing an earthquake and a tsunami.
11th of March (2.46 PM Local Time).
Yes it is very likely to happen again. It happened 70 years ago in same place it was just not as bad.
The plates moved so this can occur the earthquake.
The magnitude 9.0 quake in Japan is called the 2011 Tohoku Earthquake and also known as the Great East Japan Earthquake from sources including the Ministry of Foreign Affa…irs of Japan.
The earthquake was the moving of two plates that have been stressing for centuries, many miles away from japan. The tsunami was a result of the lifting of one plate in the oc…ean-it was giant.
It was an abduction type of quake, which means that one tectonic plate (the Pacific) slid over top of another (the North American). The effect of one part of the earth's crust… sliding over the other is the consequent quake, then tsunami and also other subtle effects such as land elevation changes (new valleys or hills may appear). Also, at this magnitude of force, the earth's rotation is increased a little more, that's why all the GPS satellites had to be recalibrated since we're now 2+ micro seconds slower.
2:46 PM (JST), MARCH 11 2011 , FRiday
because of the tectonic plates under the sea were drifting actively
The tsunami that devastated the Japan coast on March 11, 2011 was triggered by the magnitude 9.0 earthquake.
