55°25'2" N 161°53'37" W,
Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Low-level unrest continues at Pavlof Volcano. The level of seismic activity remains low and has changed little over the past day. No thermal signals or plumes were observed in satellite data over the past day. A few partly clear web camera views of the summit yesterday afternoon showed minor steam emissions at the summit, however, it was not possible to determine if ash was present in the small plume.
Although activity is currently at low levels, the degree of unrest can change quickly and it remains possible for ash and steam emissions to recommence with little or no warning.
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Nothing observed in mostly cloudy satellite images over the past day. 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.
