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.
List of earthquakes in Japan. Earthquakes M5.5+ around Japan (1900–2016) M7.0–7.9=163 EQs, M8.0+=14 EQs. [ 1] This is a list of earthquakes in Japan with either a magnitude greater than or equal to 7.0 or which caused significant damage or casualties. As indicated below, magnitude is measured on the Richter magnitude scale ( ML) or the ...
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 ...

Following are some major Japanese quakes in the last 30 years: - On Jan. 16, 1995, an earthquake with a magnitude of 7.3 hit central Japan, devastating the western port city of Kobe. The worst ...
The Tōkai earthquakes ( Japanese: 東海地震) are major earthquakes that have occurred regularly with a return period of 100 to 150 years in the Tōkai region of Japan. The Tōkai segment has been struck by earthquakes in 1498, 1605, 1707, and 1854. [ 1] Given the historic regularity of these earthquakes, Kiyoo Mogi in 1969 pointed out that ...
The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26, 1700, with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca Plate from mid- Vancouver Island, south along the Pacific Northwest coast as far as northern California. The plate slipped an average of 20 meters (66 ...
As part of the Pacific “ring of fire," Japan is one of the world's most earthquake-prone areas. A magnitude 9.0 earthquake and subsequent tsunami in March 2011 devastated large areas along Japan ...
