UNDERWATER TERRACES AND RECENT SUBSIDENCE OF THE EASTERN KAMCHATKA SHELF

Abstract

Presents the results of the seismic stratigraphic analysis of the data obtained on continuous reflection profiles shot above the subsiding areas of the E Kamchatka shelf, which are made up of sediments that were deposited under the conditions of glacio-eustatic fluctuations. The sedimentary sequences identified indicate a succession of progressive sea level falls during the Pleistocene. Data are presented on the volumes of the Pleistocene deposits on the shelf and in the basins of the eastern Kamchatka gulfs.
