ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Saturday, April 2, 2016, 1:45 PM AKDT (Saturday, April 2, 2016, 21:45 UTC)
55°25'2" N 161°53'37" W,
Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
The eruption of Pavlof Volcano has continued over the past day at a diminished level of intensity compared to the energetic phase of the eruption on Sunday and Monday. Weakly elevated surface temperatures were observed at the volcano overnight in mostly cloudy satellite images. Web camera views have been cloudy and no plumes were observed over the past day. Seismic activity remains elevated at levels above background and has been characterized by bursts of tremor.
Although the intensity of the eruption has diminished, it is possible for conditions to change at any time and more significant ash emissions may resume with little to no warning. Pauses of days to weeks are common during eruptive episodes at Pavlof. AVO will continue to monitor the volcano closely.

Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
No significant activity observed in cloudy satellite views of the volcano over the past 24 hours. No signals of note were detected 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.
