Abstract
The K–Ar isotopic age of the beginning of formation of Ichinsky (0.35) and Khangar (0.4) stratovolcanoes is established for the first time, as well as the age of the final stage of activity of the Lauchan Ridge (about 0.9 Ma) in the Sredinny Range of Kamchatka. Probably the formation of the studied volcanoes may be caused by the generation of the new deep NNE fault within the Sredinny Range of Kamchatka, which in turn was connected to the regional reasons of the increasing endogenous activity at the North-West Pacific.
