Alaska's Kanaga Volcano in the Aleutian Islands is showing signs of activity according to seismicity and observations made by AVO. The latest report states:
"Possible explosive activity and a likely ash cloud indicate new unrest at Kanaga Volcano. AVO is increasing the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY.Volcanic tremor was detected from 15:23-15:27 UTC (6:23 AM AKST) followed by numerous small events for about an hour at Kanaga Volcano. A possible weak ash cloud was also detected in AVHRR satellite data from 15:35 UTC about 39 km (24 mi) NE of the volcano.This new unrest indicates a possibility for sudden explosions of ash to occur at any time, and ash clouds exceeding 20,000 feet above sea level may develop. If a large, explosive, ash-producing event occurs, the local seismic network, satellite ash alarms, infrasound, and volcanic lightning will alert AVO to the new activity."
Kanaga's last eruptive phase was in 1994-1995, and produced large ash plumes reaching up to 20,000 meters.
