The symmetrical Amukta stratovolcano lies in the central Aleutians SW of Chagulak Island and is the westernmost of the Islands of the Four Mountains group. The stratovolcano was constructed at the northern side of an arcuate caldera-like feature that is open to the sea along the southern coast of the 8-km-wide Amukta Island. It overlies a broad shield volcano and is topped by a 400-m-wide crater, and a cinder cone is located near the NE coast. There have been several reported eruptions from both summit and flank vents.
