Terpuk

Shield volcano · Russia · 765m

The northern (right) and southern (left) summits of the Terpuk edifice are viewed here from the ESE. Both cones formed about 3,000-2,500 years ago and produced an extensive lava field. The large green vegetated patch on the foreground is a Pleistocene lava flow surrounded by the Terpuk lava flows.

Geological summary

Terpuk is a small basaltic shield volcano west of the crest of the Sredinny Range, south of Leutongey volcano, and NW of Kebeney volcano. The shield is topped by small cinder cones aligned NE-SW. Sparsely vegetated lava flows that radiate from the summit vents blocked local drainages, forming several small lakes. Topography constrains the flows to be longer toward the west, away from the crest of the range. The flows are among the youngest in the Sedankinsky Dol region and were erupted about 2,500-3,000 years ago.
