Description

From Miller and others (1998) [1] : "The undissected stratovolcano of Amukta volcano composes most of nearly circular, 7.7-km-wide Amukta Island. The cone, about 5.8 km in basal diameter and topped by a 0.4 km wide summit crater, appears on synthetic-aperture radar imagery to be built on a 300+ meter high, east-west trending arcuate ridge. Extensions of that ridge on the southwest and east sides of the island indicate an older caldera approximately 6 km in diameter and open to the sea on the south side. No hot springs or fumaroles have been reported from Amukta. Sekora (1973, p. 29) [2] reports the presence of a cinder cone near the northeastern shore of the island."

Name Origin

"Amukta volcano" is an informal name given to the peak on Amukta Island. The name Amukta (referring to the island) was reported in 1768 by Captain Lt. P.K. Krenitzin and Lt. M. Levashev (Orth, 1971).
