U.S. Geological Survey

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

Unrest continues at Pavlof Volcano. Elevated surface temperatures were observed in one satellite image over the past 24 hours, and a small steam plume remains visible in web camera images. Seismicity remains unchanged with minor activity ongoing.

Although activity is currently at low levels, the degree of unrest can change quickly and it remains possible for ash and steam emissions to begin with little or no warning. AVO is closely monitoring the volcano.

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

Low-level unrest continues at Mt. Cleveland. No activity was observed in cloudy satellite and web camera images over the past day. No significant activity was observed in seismic or infrasound (pressure sensor) data in the past 24 hours.

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.
