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.
