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.

|Diky Greben, seen here from the east along the Ozernaya River, is a Holocene lava-dome complex that formed in the center of the 20 x 25 km Pleistocene Pauzhetka volcano-tectonic depression. The initial eruptions of Diky Greben took place about 6000 years ago. Most of the volcano, particularly the thick lava flows north and south of Nepriyatnaya Mountain (left center horizon), which marks the 1070-m summit of the complex, were formed about 2000-1500 years ago.

|The Diky Greben lava-dome complex is reflected in the waters of Kurile Lake caldera. The initial eruptions of Diky Greben took place about 6000 years ago, about 2000 years after formation of the 10-km-wide Kurile Lake caldera. The eastern lava dome, seen here, is breached to the east, and was formed during the early stage of eruptions from Diky Greben. Most of Diky Greben volcano, including the unvegetated thick lava flow visible south (left) of the summit, was constructed about 2000-1500 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.
