Abstract

The research presents the phase transition zone boundaries’ topography estimates at the depths of about 410 and 660 km on the basis of data set obtained by Sakhalin island seismic station network using receiver function method. A representative data set consisting of 2500 individual PRFs was analyzed. We revealed a depression in the 660 km boundary in the central and northern parts of the island. The 410 km boundary is significantly elevated in the south Sakhalin, while within the rest of the island it is depressed in comparison to the expected standard depth. It has been suggested that the subsidence of the 410 boundary is connected with the presence of hot lower mantle matter in the phase transition zone in the northern part of the island.
