Analysis of the strongest deep earthquakes of the Okhotsk Sea has shown that these events are confined to the central part of the subduction beneath the continent cold oceanic plate with a weak plasticity at the edges. Mechanisms of sources is normal and discharges focus on several areas of a rupture. High rupture velocity and big values indicate stress drop developing process of destruction in this part of the transition zone from the upper to the lower of the Earth’s mantle.
