U.S. Geological Survey
Wednesday, December 10, 2014, 12:02 PM AKST (Wednesday, December 10, 2014, 21:02 UTC)

SHISHALDIN VOLCANO (VNUM #311360)
54°45'19" N 163°58'16" W, Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Seismic activity has remained above background over the past 24 hours. Nothing significant was observed in partly cloudy satellite images. Occasional clear views from the webcam showed minor steam emissions. A low-level lava eruption is probably still occurring within the summit crater of the volcano.

PAVLOF VOLCANO (VNUM #312030)
55°25'2" N 161°53'37" W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Seismicity at the volcano has remained at slightly above background levels over the past 24 hours. Nothing significant observed in cloudy satellite and web camera views. Pauses in vigorous eruptive activity of days to weeks are common during eruptive episodes of Pavlof Volcano, and a return to more robust eruptive activity remains possible and could occur with little or no warning.

OTHER ALASKA VOLCANOES

Other Alaska volcanoes show no signs of significant unrest: http://www.avo.alaska.edu/activity/

AVO scientists conduct daily checks of earthquake activity at all seismically-monitored volcanoes, examine web camera and satellite images for evidence of airborne ash and elevated surface temperatures, and consult other monitoring data as needed.
