Changar

Khangar volcano, also spelled Hangar, is the southernmost volcano in the Sredinny Range of western Kamchatka. It is the dominant feature within a larger volcano-tectonic depression composed of two parts: a stratovolcano with a 2-km-wide Holocene caldera, and a large lava dome on its eastern flank. The steep-walled caldera, now filled by a lake, was formed during a major explosive eruption about 7,000 years ago. An arcuate zone of pre-caldera flank lava domes nearly surrounds the volcano, and post-caldera domes form islands in the caldera lake. Late-stage olivine basalts were erupted along a NE-trending line in the southern part of the depression. The latest dated eruption took place about 500 years ago.
