The recent geodynamics of the Far East region of Russia is considered, where three large tectonic plates converge-Eurasian, North American, and Pacific, as well as several microplates-Okhotsk, Bering, and Amurian-have been hypothesized to exist. The available data on the position of the plate boundaries, the relative plate rotation poles, and the regional seismicity were analyzed, and parameters of plate motion models for northeastern Russia were determined in this study. The regional deep structure was investigated, using data obtained by different geophysical methods. The results of observations of the Magadan-Vrangel Island profile by deep seismic sounding (DSS), common-depth point (CDP) method, and correlation refraction method (CRM) are presented.
