Honshu lies at the boundary between two of these plates. An oceanic plate and … Major earthquake disasters are fortunately rare, but when they happen, it is an opportunity to learn and continue to push the boundaries of earthquake science and engineering. In Japan, the Shindo scale is commonly used to measure earthquakes by seismic intensity instead of magnitude. The quake caused no injuries and little damage.) An earthquake measuring 9.0 on the Richter Scale struck off Japan’s north-east coast, about 250 miles (400km) from Tokyo at a depth of 20 miles.

Tsunamis can also occur, with equally devastating and deadly effects. The Japan Trench is where the Pacific Ocean plate sliding under the continental place. How Shifting Plates Caused the Earthquake and Tsunami in Japan. Tsunami. Conservative boundary. Overview . The earthquake was a result of the thrust faulting near the convergent plate boundary between the Pacific Plate and the North American Plate. It was caused by the Pacific plate and the Okhotsk plate. In Japan, infrastructure — and telecommunications infrastructure in particular — has been put to the test by the biggest earthquake ever recorded in the country’s history that struck at 14:46 hours on 11 March 2011 off the eastern coast of Japan. Destructive boundary. East of Honshu, the Pacific plate is moving west at around 8–9 cm/year and is being pushed down, or subducted, underneath Honshu at the Japan Trench. The 2011 Japan Earthquake: Tōhoku. The ∼50 m slip of the Tohoku earthquake occurred along a very fine grained red-brown smectitic clay horizon subducting in the Japan Trench. The movement of the tectonic plates slipping under another tectonic plate is called subduction. STUDY. Japan earthquake 2011 Case Study What? Earthquakes are caused by motion of the Earth's tectonic plates. The Pacific Plate sinks below the North American plate along the Japan Trench, shown in this image. The tectonics are complicated, but in this animation we attempt to look at the basic mechanics of the region. The Japan earthquake had a … Earthquake and tsunami. Japan sits on or near the boundary of four tectonic plates: the Pacific, North American, Eurasian and Filipino plates. The Pacific Coastal zone, on the east coast of Japan, is particularly vulnerable as it is very densely populated. Earthquake measurement. The earthquake struck below the North Pacific Ocean, 130 kilometers (81 miles) east of Sendai, the largest city in the Tohoku region, a northern part of the island of Honshu. The sudden movement of the Pacific tectonic plate under the North American plate caused a massive earthquake and a tsunami.. Earthquakes are caused by the release of built-up pressure at plate boundaries. Due to the intensity of the earthquake, it was felt across almost the whole of Japan, being the most powerful earthquake to ever hit Japan. The epicentre of the quake was 32km down with the main shock lasting for over five minutes. We focus on two famous earthquakes: the 1995 Kobe (Great Hanshin) earthquake and the 2011 Tohoku Oki earthquake. M 9.1 - 2011 Great Tohoku Earthquake, Japan.
