Late tecnonic vertical movements of the Far East of Russia

Morphostructural analysis of the stream network of the south of the Far East has been carried out. It has been established that the latest vertical movements in the region were manifested against the background of an older, already formed and not fully eroded relief. Three stages of relief development are identified, reflecting neotectonic activity in the region: a) pre–Oligocene, characterized by a more intense uplift of the Bureinsky ridge, and less intense – the Sikhote-Alin ridge; b) Oligocene–Pliocene, characterized by the most intense vertical movements in the region during the period under review – late Eocene-Holocene; c) the Pleistocene is Holocene, during which a modern developed erosion-denudation relief was formed and no significant vertical movements occurred in amplitude. A map of the total amplitude of vertical neotectonic movements is constructed.
