The 1994 Kuril Islands earthquake occurred on October 4, 1994 at 13:22 UTC (October 5, 1994 at 00:22 local time).〔http://earthquake.usgs.gov/earthquakes/eqarchives/significant/sig_1994.php〕〔http://www.iitk.ac.in/nicee/wcee/article/11_1256.PDF〕 The magnitude of this earthquake was put at Mw 8.2, or Mj 8.1.〔"A feasibility test of CMT inversion using regional network of broad-band strong-motion seismographs for near-distance large earthquakes" by I. Cho, I. Nakanishi, and T. Sato〕 The epicenter was located at about 70 km east of the Shikotan Island. This earthquake triggered a tsunami in southern Kuril Islands and Hokkaido.〔http://www.sakhgu.ru/expert/Tsunami/Near.htm〕 The tsunami run-up height was more than 3 m in Yuzhno-Kurilsk bay and 5 m in Zelenyi Island, Russia. A peak-to-trough tsunami wave height of 346 cm was recorded in Hanasaki, Japan.〔http://earthquake.usgs.gov/earthquakes/eqarchives/significant/sig_1994.php〕 The shaking and tsunami caused road and building damage. At least 10 people were reported dead. The intensity was MSK VI~IX in Shikotan Island. Oil storage tanks in Malokurilsk and Krabozavodsk were damaged. An oil leak occurred and causing heavy contamination of the port area.〔http://www.eeri.org/lfe/pdf/Japan_KurilIslands_Insert_Jan95.pdf〕 The earthquake could be felt in Tokyo with shindo 3, and in Hokkaido, the highest intensity reached shindo 6.〔http://www.pari.go.jp/search-pdf/no0802.pdf p5〕〔http://ci.nii.ac.jp/naid/110006879701〕 This earthquake was an intra-slab earthquake within the Pacific Plate which is subducting beneath the Okhotsk Plate.〔ftp://ftp.gps.caltech.edu/pub/avouac/Ge277-2007-fall/Tanioka_GRL1995.pdf〕〔http://www.iitk.ac.in/nicee/wcee/article/11_1599.PDF〕 A numerical simulation of the tsunami suggested that the first wave was caused by a significant subsidence north of the Kuril Islands due to the earthquake.〔"Generation of Tsunamis in the Okhotsk Sea Caused by the 1994 Great Kuril Earthquake" by Y. Tanioka〕 A large aftershock of magnitude Mw 7.1 or Ms 7.7 occurred on October 9, 1994 at 07:55 UTC. It was located at 43.97° N, 148.22° E with a depth of 33 km. It generated a tsunami, and a peak-to-trough tsunami wave height of 18 cm was recorded in Hanasaki, Japan. == References ==
