Mount Amukta

The symmetrical stratovolcano Amukta forms the island Amukta with a diameter of 7.7 km and is located in the central Aleutian Islands, southwest of the island Chagulak, and is the westernmost of the Islands of Four Mountains. The volcano has a crater with a diameter of 400 meters. There is a cinder cone on the north west coast.

Well-documented reports of early activities of the volcano are sparse. Historical records show an explosive eruption phase from June 1786 to the year 1791, in which several million cubic meters of tephra were ejected as well as an outbreak in 1878. During the Eruption of February 13, 1963 both ash lava were ejected from the central crater and from side cones. The observing conditions were, however due to fog very bad, but the lava flow was observed, when he reached the sea from the west side of the crater at Traders Cove. Late August and early September 1987, a pilot observed a traffic machine is a 10.5 km high ash cloud over Iceland Amukta. Further reports of pilots about ash clouds were made on 4 September and on 18 September 1987. Beginning in July 1996 reported a boat through a 1- mile-high cloud of ash and smoke, and on March 3, 1997, an explosive eruption occurred in the central crater of the volcano.
