japan earthquake 2011 plate boundary

The earthquake was a result of the thrust faulting near the convergent plate boundary between the Pacific Plate and the North American Plate. The March 11, 2011, M9.0 earthquake near the east coast of Honshu, Japan, occurred along the subduction zone at the interface between the Pacific and North American tectonic plates. 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. Japan sits on or near the boundary of four tectonic plates: the Pacific, North American, Eurasian and Filipino plates. The magnitude 9.0 earthquake happened at 2:46 pm (local time) on Friday, March 11, 2011. On 11 March 2011 at 05:46:23 UTC, a mega earthquake (EQ) with magnitude (Mw) 9.0 [The 2011 Tohoku Earthquake] occurred at a depth of about 24 km near the East coast of Honshu Island, Japan as a result of a thrust faulting on or near the subduction plate boundary between the Pacific and North American plates.Geomagnetic data from MAGDAS and Geospatial Information Authority of Japan … Regional Information .

Japan earthquake and tsunami At 2:46pm Japanese time, on March 11th 2011, an earthquake with the magnitude of 9.0 took place 100km of the coast of Japan, and was the 5th most powerful earthquake ever recorded. 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. These both result from Japan being wedged among four major tectonic plates. As they move past each other energy is released in the form of earthquakes. OSAKA -- Research results released by Osaka University on April 29 have attributed the massive plate-boundary fault slip and tsunami of the March 2011 Great East Japan Earthquake to … The Pacific Coastal zone, on the east coast of Japan, is particularly vulnerable as it is very densely populated. In Japan, the Shindo scale is commonly used to measure earthquakes by seismic intensity instead of magnitude. Jump to Navigation Menu .

The hypocentre was offshore from Sanriku at 38.1° north and 142.9° east, at a depth of about 24 km. The Pacific Plate sinks below the North American plate along the Japan Trench, shown in this image. Today's Japan earthquake was caused by one of the most powerful quakes of the past 110 years. The Pacific Plate subducts beneath the North American Plate at approximately 83 mm per year, and descents east of Japan forming the Japan Trench. Earlier, I discussed the monitoring of seismic gaps and variations of repeat times between large earthquakes for individual fault segments along major plate boundaries in an effort to improve estimates of the timing of future events. PLAY. The epicentre of the quake was 32km down with the main shock lasting for over five minutes. This level of event is not unusual, but, on this occasion, the knock-on effects were particularly serious, as the push of the Pacific plate as it went under Japan put extra strain on an area of existing pressure build-up An oceanic plate and … By Dean Praetorius. Flashcards. At the latitude of this earthquake, the Pacific plate moves approximately westwards with respect to the North America plate at a velocity of 83 mm/yr. The earthquake, with a magnitude of 8.9, was the largest in the recorded history of Japan, and the 7th largest on record in world history. The quake caused no injuries and little damage.) 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. Felt Report - … Interactive Map . Tsunami. M 9.1 - 2011 Great Tohoku Earthquake, Japan. Gravity. Overview . Tsunamis can also occur, with equally devastating and deadly effects. In the event of the Sendai earthquake tension built up from these plates moving against each other built up and was released violently. Japan has more measurable earthquakes than any other country and has over 100 active volcanoes. 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. Japan is situated in a complicated plate boundary region where three subduction zones meet. The magnitude 9 Tohoku earthquake slipped a record 50m along a plate boundary fault comprised of extraordinarily weak smectite-rich pelagic clay [Chester et al., 2013; Ujiie et al., 2013, Fulton et al., 2013]. Honshu lies at the boundary between two of these plates. Wednesday 9 March 2011 saw a 7.2 (Richter Scale) earthquake on this plate boundary. All of the earthquakes are occurring near the boundary between the North American plate, on which northern Japan sits, and the Pacific plate.

In this region, the Pacific Plate is moving west under the North American plate at 83 millimeters per year. The movement of the tectonic plates slipping under another tectonic plate is called subduction. They can destroy buildings and infrastructure.
