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
Low-level unrest continues at Pavlof Volcano. Web camera and satellite views were obscured by clouds, but seismicity remains above background levels with periods of low-amplitude tremor observed.
The degree of unrest at Pavlof 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. Satellite observations were obscured by clouds over the past day. Web camera, seismic and pressure sensor data streams remain interrupted due to a network issue. Work is ongoing to restore data.
OTHER ALASKA VOLCANOES
Other Alaska volcanoes show no signs of significant unrest:

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.
