The Hitokappu Volcano Group [Bogatyr Ridge] on Iturup Island in the southern Kuriles consists of a cluster of late-Pleistocene to Holocene cones and craters extending ~14 km NE-SW. The basaltic andesite to andesitic Nishihitokappuyama (also known as Stokap) stratovolcano at the SW end of the ridge appears to be the location of the most recent eruptions, with a summit area that includes 8-10 cones and explosion craters, the largest of which contains a lake. The volcanic chain was constructed over a high Pleistocene base, whose glaciated surface is covered by lava flows from Nishihitokappuyama that reach to both the Pacific Ocean and the Sea of Okhotsk. JMA (2013) does not include this as a Holocene volcano.
