(11) Volcanic Activity Summary: The eruption of Pavlof Volcano that began on November 12 has intensified and the ash cloud height is currently estimated at 25,000 ft above sea level. Thus, the Aviation Color Code has been raised to RED and the Volcano Alert Level to WARNING.

The intensity of seismic tremor has increased significantly over the past 6 hours, and satellite data indicate that the ash cloud is now at an altitude of 25,000 ft above sea level. As of 11:00 am AKST (20:00 UTC) the cloud is moving towards the northwest and extends for about 125 miles (200 km) downwind.

Aviation users should refer to the National Weather Service for updated SIGMETs on the ash cloud hazard (http://aawu.arh.noaa.gov/sigmets.php). No reports of ash fallout on nearby communities have been reported, and we encourage observers to contact AVO should it occur (https://www.avo.alaska.edu/ashfall/ashreport.php).
