Three large tectonic plates converge on Russia —Eurasian, North American, and Pacific. This is a frontier region about which very little is known, but that links the tectonics of the Arctic to those of the North Pacific. The interactions of these regions are important for determining the  history of oceanic connections the two ocean basins, the tectonic evolution of Alaska and the plate motions of both North America and Eurasia.

The study of this region can address problems of continental deformation, the effect of Euler poles near plate boundaries, progressive rifting and rupturing of continental crust, development of superposed basins, evolution of large strike-slip faults, and extrusion tectonics. The plate boundary from continental northeast Russia to the Pacific Ocean has been traced along two branches, one heading to northwest Kamchatka and the Aleutian-Kamchatka corner and the other through Sakhalin to northwest Japan.

 
The Baikal Rift Zone is a divergent boundary in southeastern Russia. To the east of the Zone  is the Amur Plate which is moving away from the rift toward Japan at about 4 mm per year.
