Gunung berapi Amak

Amak, the easternmost of the Aleutian Islands, is a small island stratovolcano that lies north of the main Aleutian volcanic front, about 50 km NW of Frosty volcano on the western tip of the Alaska Peninsula. The summit of the small, roughly 1 km3 volcano is only 488 m above sea level. Blocky lava flows with prominent levees were emplaced during historical eruptions from 1700-1710 and in 1796 (Marsh, in Wood and Kienle 1990). The flows radiate from a well-defined central crater and cover much of the central part of the island. Earlier volcanism perhaps 4000-5000 years ago consisted of the emission of thin, platy andesitic lava flows. A flat alluvial plain on the S flank contains a flat-bottomed crater that may be a maar.
