Overview
Zheltovsky volcano was constructed during the last 8000 years within a 4 x 5 km caldera truncating an earlier Pleistocene edifice. A late-Holocene explosive eruption formed a 1. 6-km-wide summit crater that was subsequently largely filled by four lava domes, the latest of which forms the present summit.
Several of the lava domes were emplaced along the buried SE rim of the summit crater. More than ten cinder cones and lava domes were constructed on the flanks, particularly on the NW side. Only a few eruptions are known in historical time.
The largest, in 1923, produced explosive activity and a lava flow down the SE flank that also partly flowed into the summit crater.

About the Photo
Zheltovsky, seen here from Diky Greben volcano to its SW, was constructed during the last 8,000 years within a 4 x 5 km caldera truncating an earlier Pleistocene edifice. A late-Holocene explosive eruption formed a 1.6-km-wide summit crater that was largely filled by four lava domes, the latest of which forms the present summit. A large eruption in 1923 produced explosive activity and a lava flow down the SE flank that partially flowed into a crater.
