Development of neotectonic structures of Western Kamchatka

Abstract

Neotectonic development of Western Kamchatka does not show direct inheritance from the Bolsheretskaya depression structure. Neotectonic structure of the region is characterized with differentiated movements within separate zones. Internal and northern parts of Western Kamchatka underwent to a slow uplift controlled by uplift of Central Kamchatka mountain ridges. Maritime zone adjacent to the descending regions of the Sea of Okhotsk was relatively stable or slightly moved downward and upward. Ancient sea terraces have not been established at Western Kamchatka with the exception of low marine surfaces (up to 20 meters) within the coastal zone.
