AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Wednesday, January 18, 2017, 11:49 AM AKST (Wednesday, January 18, 2017, 20:49 UTC)


BOGOSLOF VOLCANO (VNUM #311300)
53°55'38" N 168°2'4" W, Summit Elevation 492 ft (150 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Volcanic unrest continues at Bogoslof volcano. Nothing noteworthy observed in partially cloudy satellite views of the volcano over the past day and the level of seismicity on nearby stations has been low.

Bogoslof volcano is currently quiet, but given the pattern of eruptive activity over the past month the volcano likely remains in a restless and unpredictable condition and additional eruptive bursts accompanied by volcanic clouds could occur at any time.

AVO has no ground-based volcano monitoring equipment on Bogoslof volcano. We continue to monitor satellite images, information from the Worldwide Lightning Location Network pertaining to volcanic-cloud lightning, and data from seismic and infrasound instruments on nearby islands for indications of volcanic activity.


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

Nothing significant was detected in seismic or pressure sensor data during the past 24 hours. Cloudy to partly cloudy satellite images of the volcano over the past day showed nothing noteworthy, and ice obscured web camera views.

The degree of unrest at Pavlof can change quickly. A return to eruptive activity can occur with with little or no warning.


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

Nothing of note has been observed in satellite views of Cleveland volcano over the past day. Clear views of the summit in local web camera images showed a low-level steam plume emanating from the summit crater. No significant activity was observed in seismic or pressure sensor data during the past 24 hours.

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.
