Below is a summary of eruption dates and Volcanic Explosivity Indices (VEI).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. 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. Additional discussion of data sources can be found under Volcano Data Criteria.

A group of small basaltic cinder cones on the Oka Plateau, about 200 km WNW of the SW tip of Lake Baikal, was the source of a postglacial alkalic-basalt lava flow that traveled 75 km down the Zhom-Bolok River. The morphologically youthful flow bends around glacial moraines and fills an erosional valley in an older flow dated at 12,000 +/- 4000 yrs BP (Before Present). Other young eruptions, such as those from the 90-m-high Kropotkin cinder cone and 120-m-high Peretolchin cone, produced voluminous lava flows not yet dated, and another Holocene cinder cone, Strariy, is located nearby. This area is part of the East Sayan volcanic region; Holocene activity took place in the Todzha Basin, which is separated from the Oka Plateau by the Great Sayan Ridge.
