Details for: Tanaga
Three peaks of the Tanaga volcanic complex, Sajaka, Tanaga, and East Tanaga (from left to right), are seen from the summit of Takawangha volcano. Tanaga volcano, the second largest volcanic center of the central Aleutians, is the central and highest of three youthful stratovolcanoes oriented along a roughly E-W line at the NW tip of Tanaga Island. The arcuate ridge at the lower left is part of the rim of an arcuate caldera formed by collapse of an ancestral Tanaga volcano during the Pleistocene.
