Details for: Akutan
The summit of Akutan volcano, one of the most active of the Aleutian arc, is truncated by a 2-km-wide caldera that contains a large cinder cone that rises above the caldera rim. It is seen here from the south in eruption on February 11, 1987. A small lake occupies part of the caldera floor. The caldera rim is breached narrowly on the north side. A lava flow in 1978 traveled through this gap to within 2 km of the sea. Photo by Jerry Chisum (Mark Airways), 1987 (courtesy of John Reeder, Alaska Div. Geology & Geophysical Surveys).
