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 partly cloudy to cloudy satellite images over the past 24 hours. Partly clear web camera images from yesterday afternoon showed minor steam and gas emissions from the summit vent. Nothing significant was detected in seismic or pressure sensor data over the past day.
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. Since yesterday's explosion, nothing of note has been observed in satellite data under partly cloudy to clear viewing conditions. Clear web camera images this morning showed intermittent minor steam emissions occurring within the summit crater. It is possible that these emissions contain minor amounts of ash, but the plumes are very small and are rising just slightly above the crater rim. No significant activity was detected in seismic or pressure sensor data during the past day.
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.
