Thumbnail Photo (see caption)Opala volcano, seen here from the E, lies about 50 km W of the main volcanic arc in southern Kamchatka. The edifice was constructed at the N end of the 10 x 12 km, 40,000-year-old Opala caldera. Post-caldera Holocene volcanism included the extrusion of lava domes and flows. The latest major explosion formed the Barany amphitheater on the SE flank about 1,500 years ago.

Thumbnail Photo (see caption)Late Pleistocene-Holocene scoria cones in the foreground are located on the southern part of Tolmachev Dol (Tolmachev Plateau) with Opala volcano in the background. Tolmachev Dol is a large volcanic highland NE of Opala that contains numerous postglacial scoria cones. The cones and associated lava fields cover a broad area around Lake Tolmachev halfway between Opala and Gorely.

Thumbnail Photo (see caption)The early Pleistocene Bolshaya Ipelka volcano has been extensively eroded by glaciers and has a single unnamed Holocene scoria cone on the southern flank. The conical stratovolcano to the E (right) is Opala, which was constructed along the northern rim of a large 12 x 14 km wide caldera.

Thumbnail Photo (see caption)The current Opala cone formed along the northern rim of the 13 x 19 km Pleistocene caldera that formed during the largest eruption in Kamchatka in 50,000 years, shown in this September 2018 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 15 km across). The circular feature on the SE flank is the ~1.3 x 2 km Baranii Amphitheater crater, which produced a large eruption in 1400 cal BP and was then filled with an obsidian dome.
