Khangar
"Khangar volcano, also spelled Hangar, is the southernmost volcano of the N-S-trending Sredinny Range, which stretches across western Kamchaktka. Khangar, which is the dominant feature within a larger volcano-tectonic depression, is 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 7000 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 Khangar volcano-tectonic depression. The latest dated eruption from Khangar took place about 500 years ago and marks the youngest known eruption from the Sredinny Range volcanoes."  -Smithsonian Volcano Archive
