Photo Gallery


The prominent conical Opala volcano, seen here from the east, lies about 50 km west of the main volcanic arc in southern Kamchatka. The 2475-m-high stratovolcano was constructed at the north end of the 10 x 12 km, 40,000-year-old Opala caldera. Post-caldera Holocene volcanism also included the extrusion of lava domes and rhyolitic lava flows. The latest major explosion formed the Barany amphitheater on the SE flank about 1500 years ago. Mild explosive eruptions of uncertain validity have been reported in historical time.

Late Pleistocene-Holocene cinder cones in the foreground dot the southern part of Tolmachev Dol (Tolmachev Plateau) with conical Opala stratovolcano in the background. Tolmachev Dol is a large volcanic highland NE of Opala volcano that is blanketed with numerous postglacial cinder cones. The cones and associated lava fields cover a broad area around scenic Lake Tolmachev halfway beween Opala and Gorely volcanoes.

This massive shield volcano, extensively eroded by glaciers, is the early Pleistocene Bolshaya Ipelka shield volcano, the largest volcanic structure of southern Kamchatka. A single unnamed Holocene cinder cone is found on the southern flank of Bolshaya Ipelka. The conical stratovolcano to the east (right) is Opala, which was constructed along the northern rim of a large 12 x 14 km wide caldera, whose floor is largely snow free in this NASA Space Shuttle image.
