The Amurian Plate (or Amur Plate) is a proposed continental tectonic plate covering Manchuria, the Korean Peninsula, Western Japan, and Primorsky Krai. It is not clear yet whether it is an independent plate or a part of the Eurasian Plate. It is bounded on the north and west by the Eurasian Plate, on the northeast by the Okhotsk Plate, and on the south by the Philippine Plate. Lake Baikal is considered a boundary between the Amurian Plate and the Eurasian Plate. The Amurian Plate may have been the cause of the 1976 Chinese Earthquake. The tectonic plates of the world were mapped in the second half of the 20th century. ...
