Rucharuyama, with the small pyroclastic cones of Golets and Tornyi, is SW of Moyorodake (Medvezhia) volcano at one of the narrowest parts of Iturup Island, and formed during the late Pleistocene or early Holocene. A small lava flow from the 417-m-high Tornyi cone occupies a broad glacial cirque. The 442-m-high andesitic-dacitic Golets cone, constructed above the eroded remnants of the Pleistocene Parusnaya Mountain volcano, produced lava flows that reached the coast.
The Global Volcanism Program is not aware of any Holocene eruptions from Rucharuyama [Golets-Tornyi Group]. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Rucharuyama [Golets-Tornyi Group] 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.
|Feature Name||Feature Type||Elevation||Latitude||Longitude|
|Parusnaya Mountain||Cone||406 m||45° 16' 0" N||148° 22' 0" E|
|Tornyi||Cone||417 m||45° 19' 0" N||148° 28' 0" E|
|The small pyroclastic cones of Golets and Tornyi are located near the center of the narrow Vetrovoi Isthmus in northern Iturup Island. At the upper left in this NASA Space Shuttle image (with north to the upper right) is Chirip volcano; at the lower right is Medvezhia volcano. The flat-floored caldera to the left of Medvezhia caldera is the Pleistocene Tsirk caldera. Golets and Tornyi pyroclastic cones formed during the late Pleistocene or early Holocene east (right) of the low-lying graben forming the narrow point of the peninsula.

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.
