Two closely spaced vents visible near the center of this photo produced the Bliznetsy ("Twins") lava flows. Prominent compressional ridges are visible on the flows, which were dated at about 3,000 years ago. Emplacement of the lava field was preceded by weak phreatomagmatic eruptions.

Ringkasan geologi

The Bliznetsy ("Twins") lava flows occupy a low-lying area east of the Sredinny Range and north of the Eastern Volcanic Zone volcanoes. The young flows lie south of the Ozernaya River about 80 km north of historically active Sheveluch volcano. Effusion of about 0.5 km3 of lava flows about 3000 years ago was preceded by weak phreatomagmatic eruptions.
