ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Thursday, May 19, 2016, 11:56 AM AKDT (Thursday, May 19, 2016, 19:56 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

Unrest continues at Pavlof Volcano. No observations of eruptive activity in satellite images or significant seismic tremor detected since the low-level ash emissions that were observed on May 17. Web camera views of the summit from Cold Bay were obscured by clouds over the past day.

Pauses and fluctuations in eruptive activity are typical for Pavlof. 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.


CLEVELAND VOLCANO (VNUM #311240)
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 and no signs of eruptive activity observed in satellite data over the past day, since the extrusion of a small-volume lava dome earlier in the week. No evidence of explosive activity in 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.
