    This is a considerably simpler and thinner plate-boundary fault than has been observed at other locations, [16] such as the Nankai Trough. The actual slip surface for the 2011 earthquake may not have been recovered, but it is assumed that the structures and physical properties of the core are representative of the entire fault zone.

  3. Okhotsk microplate - Wikipedia

    en.wikipedia.org/wiki/Okhotsk_microplate

    The boundary between Okhotsk microplate and Pacific plate is a subduction zone, where the Pacific plate subducts beneath the Okhotsk Plate. Many strong megathrust earthquakes occurred here, some of them among the largest on world record, including the Kamchatka earthquakes of 1737 (estimated M9.0~9.3) and 1952 (M9.0).

  4. April 2011 Miyagi earthquake - Wikipedia

    en.wikipedia.org/wiki/April_2011_Miyagi_earthquake

    The quake was a direct result of thrust faulting on or near the subduction zone plate boundary between the Pacific and North American plates. Initially estimated at a magnitude of 7.4, the tremor was felt in several areas near the east coast of Honshu as an aftershock of the 11 March magnitude 9.0 megathrust Tōhoku earthquake. The aftershock ...

    The basis for defining this tectonic boundary is the occurrence of large magnitude 7 or greater earthquakes along a linear zone from offshore Niigata Prefecture to off the west coast of Hokkaido. [7] Following the 1983 Nihonkai-Chubu earthquake , the idea of a young plate boundary was proposed, but its mechanism is unknown—it has been ...

    Earthquakes — particularly strong ones — are much more likely in places like California, which sit along major plate boundaries. Still, small earthquakes are fairly common in Georgia, experts ...

    A seismogram recorded in Massachusetts, United States. The magnitude 9.1 (M w) undersea megathrust earthquake occurred on 11 March 2011 at 14:46 JST (05:46 UTC) in the north-western Pacific Ocean at a relatively shallow depth of 32 km (20 mi), [9] [56] with its epicenter approximately 72 km (45 mi) east of the Oshika Peninsula of Tōhoku, Japan, lasting approximately six minutes.

    en.wikipedia.org/wiki/Japan_Trench

    A series of M7 earthquakes occurred at the Fukushima-oki region in 1938, registering five in total. The magnitudes were 7.4, 7.7, 7.8, 7.7 and 7.1. [5] During December 1994, transient crustal movements were recorded by a Global Positioning System (GPS) network after an inter-plate earthquake arose within the Japan Trench.

    en.wikipedia.org/wiki/Megathrust_earthquake

    In the Himalayan region, where the Indian plate subducts under the Eurasian plate, the largest recorded earthquake was the 1950 Assam–Tibet earthquake, at magnitude 8.7. It is estimated that earthquakes with magnitude 9.0 or larger are expected to occur at an interval of every 800 years, with the highest boundary being a magnitude 10, though ...
