Tectonic setting The Pacific plate, made of oceanic lithosphere, subducts beneath the Okhotsk Sea plate along a convergent boundary located off the east coast of the northern half of Japan.James D.

At this location, the Pacific plate moves approximately westward relative to the North American plate at a velocity of 70 mm/yr, subducting beneath Japan at the Japan Trench. This subduction zone is capable of producing megathrust earthquakes with magnitudes greater than 8.5, evident in the historical records. It was on the subduction interface where the 2011 Tōhoku earthquake nucleated. That event involved a rupture 220 km by 400 km on the subduction zone.Lay Thorne 2018 A review of the rupture characteristics of the 2011 Tohoku-oki Mw 9.1 earthquake Tectonophysics 733 4–36 10.1016/j.tecto.2017.09.022 2018Tectp.733....4L free Earthquake Both the United States Geological Survey (USGS) and Japan Meteorological Agency (JMA) recorded a magnitude of w 7.2 y and j 7.2 y, respectively. Its offshore epicenter was located 39 km mi east of the island of Kinkasan in Miyagi Prefecture. The focal mechanism corresponded to thrust faulting on the Japan Trench. A rupture area of 135 km mi x 60 km mi was estimated, with a maximum slip of 2.2621 m ft west of the epicenter. The observed source time function gives a 20 second duration for the earthquake, with the greatest phase of seismic moment release occurring about five seconds after initiation. On the Modified Mercalli intensity scale (MMI), a maximum intensity of VII (Very strong) was recorded at Ishinomaki and areas along the Oshika Peninsula, while in Sendai, the MMI reached VI (Strong). A maximum peak ground acceleration of 0.52 g was recorded at Kurihara, Miyagi, while a station at Yamamoto recorded a peak velocity of 31 cm/s. By the end of 2005, 19 aftershocks of w 4.0 or higher were recorded by the USGS;USGS earthquake catalog United States Geological Survey https://earthquake.usgs.gov/earthquakes/map/?extent=37.10119,140.10315&extent=39.2918,144.49768&range=search&timeZone=utc&search=%7B%22name%22:%22Search%20Results%22,%22params%22:%7B%22endtime%22:%222005-12-31T23:46:28.400Z%22,%22latitude%22:38.276,%22longitude%22:142.039,%22maxradiuskm%22:70,%22minmagnitude%22:4,%22starttime%22:%222005-07-26T02:46:28.400Z%22%7D%7D the largest aftershock measured w 6.5, striking on 2 December with an epicenter southeast of the mainshock.M 6.5 - 80 km ESE of Ishinomaki, Japan 2005 usp000e5c8 A tsunami advisory was issued by the JMA, but was lifted shortly after.

One landslide was also reported at an unspecified location. Bullet trains were suspended, three nuclear power stations were shut down automatically for safety checks, and flights at Haneda Airport in Tokyo were temporarily halted as a precaution. Some 17,000 households were reported to have lost power.August 16, 2005 Earthquake rocks northern Japan BBC News http://news.bbc.co.uk/2/hi/asia-pacific/4155026.stm June 20, 2006 https://web.archive.org/web/20060613194327/http://news.bbc.co.uk/2/hi/asia-pacific/4155026.stm June 13, 2006 live See also List of earthquakes in 2005 List of earthquakes in Japan March 2021 Miyagi earthquake References Further reading Earth Planets Space 58 12 1533–1597 2006 Special Section for the 2005 M7.2 Miyagi-oki earthquake 2006EP&S...58.1533K Kanamori H Hiroo Kanamori Miyazawa M Mori J 10.1186/BF03352657 free External links Headquarters for Earthquake Research Seismological notes from the Earthquake Research Institute, The University of Tokyo 7396432 Category:Earthquakes of the Heisei era Miyagi Earthquake, 2005 Miyagi earthquake Category:August 2005 in Japan Category:Earthquakes in Miyagi Prefecture Category:2005 disasters in Japan
