A large group of Pleistocene-to-Holocene basaltic pyroclastic cones and associated lava flows (Masurenkov, 1980) fills a topographic low north of Ksudach volcano and SW of Khodutka volcano. The Pleistocene Plosky volcano and the Holocene shield volcano Olkoviy lie near the north end of this group of NE-SW-trending cones. The small 636-m-high Olkoviy shield volcano rises 350 m above the valley floor. Growth of the cone diverted the headwaters of the Savan River in a broad arc to the east. The eastern and southern margins of the volcanic field are bounded by the Pravaya Khodutka and Zapadnaya Khodutka Rivers, respectively.

The Global Volcanism Program is not aware of any Holocene eruptions from Olkoviy Volcanic Group. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Olkoviy Volcanic 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.

The linear group of mostly snow-free pyroclastic cones and associated lava flows right of the center of this NASA Space Shuttle image (with north to the right) is the southern part of the Olkoviy volcano group. This large group of Pleistocene-to-Holocene basaltic shield volcanoes and pyroclastic cones is named for Olkoviy shield volcano, which lies out of view at the northern end of the volcanic field. Ksudach volcano is partially visible at the far left, and the circular, low-angle, snow-free Ozernoy shield volcano lies above and to its right.

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.
