* The Eurasian Plate: The vast majority of Russia, including its European portion and much of Siberia, sits on the Eurasian Plate.

* The North American Plate: A small portion of eastern Russia, specifically the Chukotka Peninsula and the Diomede Islands, is situated on the North American Plate.

This is due to the fact that the boundary between the two plates runs through the Bering Strait, separating Russia and Alaska.
