Komarov volcano (also known as Komarova) is a complex structure situated at the northern half of the Gamchen ridge. An eccentric 2.5 x 4 km caldera contains a young twin cone and flank explosive domes. The youngest cone, 2065-m-high Komarov, was built at the western end of the caldera. It is capped by two craters, one at the summit and the other on the upper east flank. Lengthy Holocene lava flows extend beyond the caldera to the east and west. Growth began about 1500 years ago following cessation of activity at Vysoky volcano. No historical eruptions are known, but the summit region has undergone extensive hydrothermal alteration, and fumarolic areas occur there and on the northern and southern flanks.

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 Komarov volcanic complex is seen in the foreground in this view from the north toward the southern part of the Gamchen volcanic range. The youngest cone of the Komarov complex, 2070-m-high Komarov, was built at the western end of a 2.5 x 4 km caldera. It is capped by two craters, one at the summit and the other on the upper east flank. The Gamchen massif beyond Komarov consists of three Late-Pleistocene and one Holocene cones. The perfect cone of Kronotsky volcano is seen on the far right horizon.

|Hydrothermally altered rocks form the summit ridge of Komarov volcano (also known as Komarova) in this view from the east. Komarov is a complex structure situated in the northern half of the Gamchen ridge and lies at the western end of a 2.5 x 4 km caldera. Lengthy Holocene lava flows, such as the one in the foreground, extend beyond the caldera to the east and west. Although no historical eruptions are known from Komarov, growth of the young volcano began only about 1500 years ago.

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.
