Chirippusan (also simply Chirip) volcano is on the Chirip Peninsula, which extends N into the Sea of Okhotsk from central Iturup Island. The summits of two overlapping stratovolcanoes are ~4.5 km apart along a volcanic ridge, with Kitachirippusan on the north and Minamichirippu (also called Bogdan Khmelnitskii) on the south. Lava flows from both edifices are truncated by a large 4-km-wide depression on the west side of the peninsula. Basaltic rocks dominate at both volcanoes over basaltic andesite and andesitic products. Kitachirippusan has a shallow summit crater, partially filled by a small lake, that has fed lava flows down all sides; satellitic cones are located on the northern flank. Lava flows from Minamichirippusan reach the coast on both the east and west. Only two eruptions are known, one in 1843 CE and another in 1860 CE from a vent SE of the Minamichirippusan summit.
