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 4-km-wide depression on the west side of the peninsula. Basaltic rocks dominate at both 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; cones are located on the N flank. Lava flows from Minamichirippusan reach the coast on both the east and west. Eruptions or possible activity has been listed in various catalogs and references for 1843, 1857, 1860, and 1879 CE. However, no original sources, deposits, or descriptions have been identified. No clear evidence for Holocene eruptive activity is known. Satellite imagery shows a scarp open to the W that extends 1.5 km between the main summits, where largely unvegetated areas extend 1 km into the valley. The exposed areas have a yellow color, suggesting fumarolic activity and possible avalanche collapses of the ridge.
