The Udokan Plateau volcano is a volcanic field located in southeastern Russia 400 km ENE of the Baikal Lake. The field contains cinder cones, lava domes, lava flows and explosion craters (maars).
The latest eruption took place at Chepe volcano about 2200 years ago.

Background
The Udokan Plateau volcanic field belongs to a 3000 sq km large area of quaternary volcanism at the eastern margin of the Baikal Rift System. Activity in this area dates back to the Miocene.Late-Pleistocene to Holocene volcanic centers are concentrated along 3 major lineaments, and many eruptions were localized along fissures trending NW-SE and NE-SW.
Dated Holocene volcanic centers are located on a 20-km-long line at the SW side of the volcanic field, but Holocene cinder cones also occur in the NE Udokan Plateau.
Seismic activity has been recorded at depths of 15 to 20 km beneath some of the cones. The Udokan volcanic field is dominated by basaltic cinder cones, but basal trachytic ignimbrites are also overlain by lava domes and flows, and trachytic maars were formed during the final stages of activity.

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.
