The Nishihitokappuyama [Bogatyr Ridge] volcano on Iturup Island in the southern Kuriles consists of a cluster of small NE-SW-trending late-Pleistocene to Holocene cones and craters, along with the larger Stokap stratovolcano at the SW end of the ridge. The basaltic-andesite to andesitic Stokap is capped by a complex of 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 Stokap that reach to both the Pacific Ocean and the Sea of Okhotsk. No historical eruptions are known from the volcanic chain.

The Global Volcanism Program is not aware of any Holocene eruptions from Nishihitokappuyama [Bogatyr Ridge]. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Nishihitokappuyama [Bogatyr Ridge] page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The Bogatyr Ridge, seen here looking southward across Iturup Island, consists of a cluster of small NE-SW-trending late-Pleistocene to Holocene cones and craters. The larger Stokap stratovolcano (upper left) occupies the SW end of the ridge. Stokap volcano is capped by a complex of 8-10 cones and explosion craters, the largest of which contains a lake. The volcanic chain was constructed over a high Pleistocene base of glaciated Pleistocene volcanic rocks. No historical eruptions are known from the volcanic chain.

Snow-capped Stokap volcano (center) lies at the SW end of Bogatyr Ridge, an elongated chain of small volcanoes on southern Iturup Island. Bogatyr Ridge (left of Stokap) consists of a cluster of small NE-SW-trending late-Pleistocene to Holocene cones and craters. Stokap volcano is capped by a complex of 8-10 cones and explosion craters, the largest of which contains a lake. The slopes of conical Atsonupuri volcano form the ridge in the right foreground.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
