AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Monday, October 31, 2016, 2:03 PM AKDT (Monday, October 31, 2016, 22:03 UTC)


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

Low-level unrest continues at Pavlof Volcano. No activity was detected in cloudy satellite and web camera images over the past 24 hours. Nothing significant was detected in seismic or pressure sensor data over the past day.

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

Unrest continues at Cleveland Volcano. Nothing of note has been observed in satellite data in mostly cloudy views of the volcano over the past day. Views of the volcano by web camera have also been obscured by clouds over the past day. No significant activity has been detected in seismic or pressure sensor data.

Clear satellite views of the summit region late last week show that the 24 October explosion destroyed most of the previous dome, leaving a deep crater in its place. These observations are consistent with post-explosion web camera images that showed darkened areas around the summit region, and that were interpreted as minor ash deposits from the explosion.


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.
