February 19, 2012 – Mount Kanaga Volcano Exhibiting Explosive Activity: A view looking west, at the 1,312 meter (4,304 feet) high Kanaga Volcano in eruption. Kanaga is located about 25 km (16 mi) west of the U.S. Navy installation and port on Adak Island in the Aleutian Islands. The volcano erupted intermittently through much of 1994, dusting the community of Adak at least once with fine ash.
The Alaska Volcano Observatory has raised the alert level for the Kanaga volcano, in the remote Aleutian Islands. Scientists on Saturday said possible explosive activity and a likely ash cloud indicate new unrest at Kanaga Volcano, leading it to raise the volcano alert level from normal to advisory. The observatory says volcanic tremor was detected at about 6:23AM Saturday. The unrest indicates the possibility of sudden explosions of ash to occur at any time, and ash clouds exceeding 20,000 feet above sea level may develop. Ash clouds above 20,000 feet from Alaska volcanoes are a threat to trans-Pacific air carriers. Kanaga Volcano is located about 1,215 miles southwest of Anchorage in the western Aleutian Islands.
