Gunung api perisai · Russia · 1936 m

The red Tobeltsen scoria cone, seen from the SE, lies on the lower WSW flank of Severny erupted about 3,500 years ago and was the source of lava flows that descend diagonally to the lower left. Severny is a late-Quaternary volcano located at the NW end of a major NE-trending graben along the crest of the northern Sredinny Range.

Ringkasan geologi

Severny is a late Quaternary shield volcano located at the NW end of a major NE-trending graben along the crest of the northern Sredinny Range. It is capped by a small stratovolcano, a small shield volcano was constructed on its SW flank, and an even smaller shield grew on the NE flank. The basaltic Tobeltsen cinder cone on the WSW flank and associated lava flows were erupted about 3,500 years ago.
