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

Unrest continues at Pavlof. Seismicity has been low over the past day and occasional small, discrete seismic events are continuing. Satellite and web camera images have been obscured by clouds over the past day.

Activity is currently at low levels. An increase in eruptive activity is possible and could occur with little or no warning. AVO will continue to monitor 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

Unrest continues. Thermal signals were observed in two satellite images over the past day; all other satellite views of the summit obscured by clouds. Clear web camera views within the past hour showed nothing of note at the summit of the volcano. No significant activity observed in seismic or infrasound (pressure sensor) data.

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.
