The Berutarubesan andesitic-to-dacitic stratovolcano forms the SW tip of Iturup Island in the southern Kuriles. The flanks are deeply dissected by wide glacial valleys; a low saddle on the NE side separates it from the slopes of the Moekeshiwan [Lvinaya Past] caldera. The only known Holocene activity produced a small pyroclastic cone that was superposed on the intersecting headwalls of U-shaped valleys and cirques on the broad eroded summit. The hydrothermally altered summit cone was the source of two small lava flows. Gorshkov (1970) estimated that eruptions ceased only a few hundred to at most 1,000 years ago. No confirmed eruptions are known, although there are fumarolic areas near the summit with sulfur deposits.
