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. Seismicity remains low. Satellite data suggest minor changes in the small dome that was first noted on May 18. The dome has grown slightly and is about 60-meters (197 ft) in diameter compared to 50-meters (165 ft) in diameter on May 18, 2016. No other signs of eruptive activity have been observed in satellite or pressure sensor data today.
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. Seismicity remains low. Clouds obscured views of the volcano by satellite and web camera today.
Pauses in activity of days to weeks are common during eruptive episodes of Pavlof Volcano. A return to eruptive activity remains possible and could occur with little or no warning. Thus, AVO will continue to monitor the volcano closely and will issue additional information as necessary.
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.
