Stratovulcano · United States · 893 m

The southern half of 5 x 10 km Kagamil Island in the NE part of the "Islands of Four Mountains" group contains two postglacial cones with small summit craters. The larger cone (center) is seen here from the SW and is located at the SE end. Hot springs and fumaroles occur near the SE coast.

Kagamil Island lies near the NE end of the Islands of the Four Mountains archipelago in the central Aleutians, between Chuginadak and Uliaga Islands. The southern half of the 5 x 10 km island contains two undissected cones of postglacial age with small summit craters. The larger cone is located at the SE end of the NNW-SSE-trending volcano. Arcuate ridges at the northern and southern ends of the island suggest a possible earlier caldera. Hot springs and fumaroles occur along a steaming beach at the SE coast. The early explorer Veniaminof (1840) indicated that Kagamil formerly "flamed and smoked," but the only eruptive report is of unspecified activity in 1929 (Coats 1950).

Riassunto in inglese

Kagamil Island, in the Islands of Four Mountains subgroup of the Aleutian archipelago, is 3.7 miles (6.0 km) north of Chuginadak Island and 1.2 miles (1.9 km) south of Uliaga Island. It is 6.2 miles (10.0 km) in length and up to 3.1 miles (5.0 km) in width. The southern half of the island is dominated by the Kagamil Volcano, which has two summits: one is 2,930 feet (890 m) above sea level, while the other is lower at 2,260 feet (690 m).
