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.
English: This animation shows how PTWC's real-time tsunami forecast model, RIFT, predicts the behavior of the tsunami following the 9.0 magnitude earthquake offshore of the Tōhoku-Oki region, Japan, on 11 March 2011. This version uses the USGS finite fault model (link below) as the source mechanism for the tsunami model, therefore the ...
2021 Fukushima earthquake. / 37.720; 141.762. Multiple. The largest is an Mw 6.0. An intense and deadly seismic event struck offshore east of Tōhoku, Japan. The M JMA 7.3 or M w 7.1 earthquake occurred on a Saturday night at 23:07 JST (14:07 UTC) on 13 February at a focal depth of 44.0 kilometers (27.3 mi). [ 6]
Scientists recorded a slow-slip event in 2011 before the magnitude-9 Tohoku earthquake and tsunami in Japan, which killed more than 18,000 people and touched off the Fukushima nuclear disaster.
The earthquake caused a tsunami which struck the west coast of North America and the coast of Japan. [3] Japanese tsunami records, along with reconstructions of the wave moving across the ocean, put the earthquake at about 9:00 PM Pacific Time on the evening of 26 January 1700. [4]
In Chuckchucha and Lapati, the tsunami arrived in a three-wave cycle with a maximum tsunami wave height of 12 m (39 ft). In Campbell Bay of Great Nicobar Island, the tsunami waves hit the area three times with an inundation limit of 250–500 m (820–1,640 ft). A rise in sea level was observed before the first wave came within 5 minutes of the ...
A powerful earthquake measuring magnitude 7.1 struck southwestern Japan, triggering tsunami warnings for a number of the country’s western islands. The tremor occurred off the coast of Miyazaki ...
When the tsunami's wave peak reaches the shore, the resulting temporary rise in sea level is termed run up. Run up is measured in metres above a reference sea level. [56] A large tsunami may feature multiple waves arriving over a period of hours, with significant time between the wave crests.
