AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Monday, February 9, 2015, 12:31 PM AKST (Monday, February 9, 2015, 21:31 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

Elevated surface temperatures at the summit were observed in satellite data in the past 24 hours. Web camera images show a light steam plume over the last 24 hours. Seismicity has increased slightly over the last several hours. It is unknown if this increase will result in ash emissions or explosions. This morning the volcano has been obscured by clouds in both satellite and web camera views. AVO is monitoring the volcano closely.

CLEVELAND VOLCANO (VNUM #311240)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

No activity was detected in cloudy to partly cloudy satellite data and web camera images in the last 24 hours. No significant events in seismic or infrasound (air pressure) data were detected.

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.
