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.</p>IchinskyKhangarLauchanSredinny Range of Kamchatkavolcanism, K-Ar datingИчинскийХангарЛаучанСрединный хребет КамчаткивулканизмK–Ar-датирование[Базанова Л.И., Певзнер М.М. // ДАН. 2001.
