Photo Gallery

The grayish area to the left of the clouds near the center of the NASA Landsat image (with north to the top) is the Bliznetsy ("Twins") lava flows. These flows were erupted about 3000 years ago in a low-lying area east of the Sredinny Range and south of the Ozernaya River, which is visible cutting diagonally across the upper right part of the image. The unusual location of this recently studied young volcanic vent lies north of the margin of the subducting Pacific Plate.

Two closely spaced vents visible near the center of this photo produced the Bliznetsy ("Twins") lava flows. Prominent flow levees are visible on the flows, which were dated at about 3000 years ago. Emplacement of the ca. 0.15 cu km lava field was preceded by weak phreatomagmatic eruptions.
