Abstract

Abstract: The specific morphology of the inner and outer slopes of the eastern Kuril–Kamchatka Trench were revealed based on joint study of bathymetry and seismic profiles obtained in two RV Sonne cruises and previous investigations. Three segments of ocean floor differing in relief, thickness of sediments and tectonic activity were distinguished on the outer slope. Their subduction under Eastern Kamchatka governs the recent morphology of the accretionary wedge in the area between the Krusenstern Fault and Uglovoe Rise. The Krusenstern Fault, Obruchev Rise, and Naturalist Fault control segmentation of the trench’s island slope and seismic regime in this section of Kuril–Kamchatka subduction zone.
