A group of four small basaltic shield volcanoes and cinder cones of late-Pleistocene to Holocene age is located along a 20-km-long NW-SE-trending line along the south side of Avacha Bay (Luchitsky, 1974). One of the volcanoes forms a narrow peninsula extending NW into Avacha Bay NW of the town of Tar'ya, another lies south of Avacha Bay, and the SE-most of these volcanoes lies near the Pacific coast opposite Sarannay Bay. A linear group of small dacitic-to-rhyolitic lava domes of Pleistocene age lies along a NE-SW trend near the shore of the bay.

The Global Volcanism Program is not aware of any Holocene eruptions from Unnamed. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Unnamed page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Unnamed.

Avacha Bay fills the center of this Space Shuttle image with north to the upper left; the city of Petropavlovsk-Kamchatskiy lies at the NE end of the bay. A group of four small basaltic shield volcanoes and cinder cones is located along a 20-km-long NW-SE-trending line along the south side of the bay. The northernmost of these volcanoes occupies the narrow peninsula extending toward the lower left into Avacha Bay. The SE-most of these volcanoes lies near the Pacific coast opposite Sarannay Bay (lower right).

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
