TheAmur plate (orAmurian plate; also occasionally referred to as theChina plate, not to be confused with theYangtze plate)[citation needed] is a minortectonic plate in thenorthern andeastern hemispheres.
The Amurian Plate is named after theAmur River, which forms the border between the Russian Far East andNortheast China.It is bounded on the north, west, and southwest by theEurasian plate, on the east by theOkhotsk plate, to the southeast by thePhilippine Sea plate along theSuruga Trough and theNankai Trough, and theOkinawa plate, and theYangtze plate.[1]
The Amurian Plate may have been involved in the1975 Haicheng earthquake and the1976 Tangshan earthquake in China.[citation needed]
The Amurian microplate is a division within the Eurasian plate, with an unknown western boundary, defined on the south by the Qinling suture zone[additional citation(s) needed] in central China and theBaikal Rift Zone andStanovoy Mountains on the north.[2]
TheBaikal Rift Zone is considered a boundary between the Amurian Plate and the Eurasian plate. GPS measurements indicate that the plate is slowly rotating counterclockwise. The boundary with the Okhotsk Plate is theeastern margin of the Sea of Japan.[3]
