AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Tuesday, March 29, 2016, 9:25 AM AKDT (Tuesday, March 29, 2016, 17:25 UTC)


PAVLOF VOLCANO (VNUM #312030)
55°25'2" N 161°53'37" W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Ash emission from Pavlof decreased throughout the night, and in a satellite image from this morning at 14:25 UTC (6:25 am AKDT) appears to have diminished to the point where it is difficult to observe. Areas of drifting remnant ash from the energetic emissions of the previous day continue to be observed in satellite data over Bristol Bay and Interior Alaska. A clear webcam view from this morning confirms intermittent low-level ash emissions at the volcano at an altitude below 15,000 ft. Seismic activity remains elevated above background levels. The intensity of thermal activity observed in satellite data has also decreased over the past day. Updated information about the location and forecasted movement of the volcanic ash cloud can be found at National Weather Service Alaska Aviation Weather Unit http://aawu.arh.noaa.gov/

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. AVO will continue to monitor the volcano closely.


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.
