[1] Thefirst25h oftheaftershock sequence following the11 March2011 M w 9.0Tohoku, Japan earthquake is investigated using a backprojection method. The Tohoku-Oki earthquake has caused large variations in the stress field both near the source and far from the epicenter, causing a significant increase in seismic activity in the crust of the overriding plate west of the source area (Okada et al., 2011).Thousands of aftershocks occurred in the first few months following the Tohoku-Oki earthquake. The event began with a powerful earthquake off the coast of Honshu, Japan’s main island, which initiated a series of large tsunami waves that … Japan earthquake and tsunami, severe natural disaster that occurred in northeastern Japan on March 11, 2011, and killed at least 20,000 people. For conciseness, only earthquakes with magnitudes greater than 7.0 or an intensity greater than lower-6 on the shindo scale are listed here.

This is a list of foreshocks and aftershocks of the 2011 Tōhoku earthquake.Japan had experienced 900 aftershocks after the M9.1 earthquake on March 11, 2011 with about 60 aftershocks being over magnitude 6.0 and three over magnitude 7.0. Aftershocks Great Tohoku earthquake (north-east Honshu, Japan) 2011 Last update 14.54 12/4/2011 Hidden aftershocks of the 2011 Mw 9.0 Tohoku, Japan earthquake imaged with the backprojection method Eric Kiser1,2 and Miaki Ishii1 Received 25 February 2013; revised 30 August 2013; accepted 2 October 2013; published 29 October 2013. Japan earthquake: social aftershocks of Fukushima disaster are still being felt November 23, 2016 6.05am EST Becky Alexis-Martin , University of Southampton , Thom Davies , University of Warwick The event began with a powerful earthquake off the coast of Honshu, Japan’s main island, which initiated a series of large … Japan earthquake and tsunami, severe natural disaster that occurred in northeastern Japan on March 11, 2011, and killed at least 20,000 people. In addition, tsunamis associated with the earthquake were measured over a wide area, from Hokkaido to Okinawa, mainly along the Pacific side of the Tohoku Region and the northern part of the Kanto Region, as shown in Fig. This report presents an outline of the earthquake and summarizes the associated seismic damage to social infrastructure facilities. [1] On 11 March 2011, the Tohoku‐oki earthquake in eastern Japan and the devastating tsunami that followed it caused severe damage and numerous deaths. The 2011 off the Pacific Coast of Tohoku Earthquake, which occurred on March 11, 2011, caused enormous damage, particularly to the strip of land along the Pacific Ocean from the Tohoku Region to the Kanto Region, due to seismic motion and the tsunami it triggered. The Tohoku-Oki earthquake has caused large variations in the stress field both near the source and far from the epicenter, causing a significant increase in seismic activity in the crust of the overriding plate west of the source area (Okada et al., 2011).Thousands of aftershocks occurred in the first few months following the Tohoku-Oki earthquake. Rupture process of the 2011 Tohoku‐oki earthquake and absolute elastic strain release Yuji Yagi1 and Yukitoshi Fukahata2 Received 5 July 2011; revised 7 September 2011; accepted 7 September 2011; published 13 October 2011. So far, 5,229 aftershocks have rattled the tectonic boundary that ruptured off the coast of Japan's Tohoku region in March 2011. In total, …
