The rocks of the summit part of the volcano are strongly altered due to hydrothermal activity. Lava flows of the volcano formed about 1500 14C years BP, and are covered by SH2 (1000 14C years BP) and SH3 (1400 14C years BP) marker ashes from Shiveluch volcano as well as by ashes from recent Komarov eruptions.
