ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Tuesday, August 2, 2016, 11:48 AM AKDT (Tuesday, August 2, 2016, 19:48 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
Low-level unrest continues at Pavlof, but appears to be declining. The level of seismic activity remains low and nothing noteworthy was observed in seismic data over the past day. A weak thermal signal was observed in satellite data this morning, but clouds and fog have obscured views of the volcano in web camera images over the past day.
Although activity is currently at low levels, the degree of unrest can change quickly and it remains possible for ash and steam emissions to commence with little or no warning.

Unrest continues. Thermal signals at the volcano were observed in several satellite images over the past day. No significant activity observed 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.
