The Amur plate (or Amurian plate; also occasionally referred to as the China plate, not to be confused with the Yangtze plate){{citation needed|date=February 2024}} is a minor tectonic plate in the northern and eastern hemispheres.
The Amurian Plate is named after the Amur River, which forms the border between the Russian Far East and Northeast China.
It is bounded on the north, west, and southwest by the Eurasian plate, on the east by the Okhotsk plate, to the southeast by the Philippine Sea plate along the Suruga Trough and the Nankai Trough, and the Okinawa plate, and the Yangtze plate.Yu. F. Malyshev, et al. Deep structure of the Amur lithospheric Plate border zone.
The Amurian Plate may have been involved in the 1975 Haicheng earthquake and the 1976 Tangshan earthquake in China.{{Citation needed|date=April 2021}}
Boundaries
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 needed|date=February 2024}} in central China and the Baikal Rift Zone and Stanovoy Mountains on the north.{{cite book |last1=Barnes |first1=Gina L. |title=Tectonic Archaeology: Subduction Zone Geology in Japan and Its Archaeological Implications |date=2022 |publisher=Archaeopress Publishing Limited |pages=35–6}}
The Baikal 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 the eastern margin of the Sea of Japan.{{cite journal |last1=Nakamura |first1=K. |title=Possible nascent trench along the eastern Japan Sea as the convergent boundary between Eurasian and North American plates |journal=Bull.

Geography
