The Eurasian plate is a tectonic plate that includes most of Eurasia (a landmass consisting of the traditional continents of Asia and Europe), with the notable exceptions of the Arabian Peninsula, the Indian subcontinent, and the area east of the Chersky Range in eastern Siberia.

[7] There are different maps for it based on recent tectonics, seismicity and earthquake focal mechanism.

The simplest plate geometry draws the boundary from the Nansen Ridge through a broad zone of deformation in North Asia to the Sea of Okhotsk then south through Sakhalin Island and Hokkaido to the triple junction in the Japan Trench.

[8] But this simple view has been successfully challenged by more recent research.

New research in the 1990s supported that the Okhotsk microplate was independent from the North American plate and a boundary with the Amurian microplate, sometimes described as "a division within the Eurasian plate"[additional citation(s) needed] with an unknown western boundary.
