Okhotsk Plate


The Okhotsk Plate is a minor tectonic plate covering the Sea of Okhotsk, the Kamchatka Peninsula, Sakhalin Island and Tōhoku and Hokkaidō in Japan It was formerly considered a part of the North American Plate, but recent studies indicate that it is an independent plate, bounded on the north by the North American Plate1 The boundary is a left-lateral moving transform fault, the Ulakhan Fault On the east, the plate is bounded by the Pacific Plate at the Kuril-Kamchatka Trench and the Japan Trench, on the south by the Philippine Sea Plate at the Nankai Trough, on the west by the Eurasian Plate, and possibly on the southwest by the Amurian Plate2

Geologyedit

The boundary between Okhotsk Plate and Amurian Plate might be responsible for many strong earthquakes that occurred in the Sea of Japan as well as in the Sakhalin island, such as the MW71 MS75 according to other sources earthquake of May 27, 1995 in northern Sakhalin345 The earthquake devastated Neftegorsk, and the town was not rebuilt after the earthquake Other notable intraplate earthquakes such as the 1983 Sea of Japan earthquake and the 1993 Hokkaidō earthquake triggered tsunamis in the Sea of Japan

The boundary between Okhotsk Plate and Pacific Plate is a subduction zone, where Pacific Plate subducts beneath the Okhotsk Plate Many strong megathrust earthquakes occurred here, some of them among the largest on world record, including the Kamchatka earthquakes of 1737 estimated M90~93 and 1952 M90 Such strong megathrust earthquakes can also occur near the Kuril Islands, as the M83 earthquake of November 15, 2006,67 Hokkaido, as the M83 earthquake of September 26, 200389 and the M90 2011 Tōhoku earthquake off the coast of Honshu

GPS measurements and other studies show that the Okhotsk Plate is slowly rotating in a clockwise direction Models indicate that it rotates 02 deg/Myr about a pole located north of Sakhalin10
