Alaska Volcano Observatory

Kasatochi Volcano is a spectacular stratocone that forms a small island in Aleutians between Adak and Atka Islands. The summit was destroyed during a large explosive event perhaps only a few hundred years ago, exposing the innards of this dramatic volcano. Records of historic activity are sparse, in part because of the remoteness of Kasatochi. In the last several years, USFWS personnel stationed on the island have noticed evidence of degassing through this lake, testimony to the youthfulness of the volcano. Photo taken from the southern rim of the caldera by Brie Drummond, USFWS in August, 2004.
