Vorlage:Current disaster Vorlage:Earthquake
The 2008 Iwate earthquake, officially named by the Japan Meteorological Agency the Iwate-Miyagi Nairiku Earthquake in 2008,[1] struck northeastern Honshū, Japan, on June 14, 2008.[2] The earthquake occurred in Iwate Prefecture at Vorlage:Coor d (about Vorlage:Convert north-northwest of Sendai, Vorlage:Convert north of Tokyo) at 8:43 am JST on June 14, 2008 (2008-06-13 23:43Z[3]). The magnitude of the quake was 7.2.[4] The strongest shaking was recorded in Ōshū, Iwate and Kurihara, Miyagi, both of which recorded a shindo of 6+.[5] The United States Geological Survey placed the magnitude at 6.8.[6]
Tectonics
Vorlage:Seealso According to the USGS:[7]
The Mw 6.8 Honshu earthquake of June 13th 2008 occurred in a region of convergence between the Pacific Plate and the Okhotsk section of the North American Plate in northern Japan, where the Pacific plate is moving west-northwest with respect to North America at a rate of approximately 8.3 cm/yr. The hypocenter of the earthquake indicates shallow thrusting motion in the upper (Okhotsk) plate, above the subducting Pacific plate, which lies at approximately 80 km depth at this location.
The earthquake occurred in a region of upper-plate contraction, probably within the complicated tectonics of the Ou Backbone Range, known to have hosted several large earthquakes in historic times. The largest of these events occurred in 1896, approximately 70km north of the June 13th event, and killed over 200 people in the local area.
Effects
It killed at least nine people, and injured 233 others. Eleven are missing.[8] One death was attributed to a landslide; another occurred when a truck struck a man. Service interruption on the Tōhoku, Akita, and Yamagata Shinkansen lines affected 2,000 passengers aboard trains,[9] and local lines and expressways closed.[10] Service on the Shinkansen lines returned to normal by the following morning.[11] In the city of Ōshū, a bus overturned and fell into a stream.[12]
Shaking was palpable over a wide region. Shindo 3 or above was reported in Miyagi, Iwate, Akita, Yamagata, Fukushima, Aomori, Tochigi, Ibaraki, Niigata, Chiba, Saitama, Tokyo, Hokkaidō, Kanagawa, and Gunma Prefectures.[13]
There were no shutdowns of nuclear power plants due to the quake like the 2007 Chūetsu offshore earthquake. Some water was found to have splashed out of spent fuel pools in the Fukushima and Onagawa plants due to shaking. Nothing was released to the environment.[14]
