BackgroundA 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.
