AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Thursday, January 5, 2017, 3:05 PM AKST (Friday, January 6, 2017, 00:05 UTC)


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

The explosion at 13:24 AKST (22:24 UTC) today was short-lived with an estimated duration of about 5 minutes. The volcanic cloud from the event is visible in satellite data moving north from the volcano as a detached cloud at an estimated height of 35,000 ft asl. A pilot also reports seeing the cloud at 35,000 ft asl.

Additional explosive events at Bogoslof may occur without warning. Due to the unpredictability of the situation, the Aviation Color Code remains RED and the Volcano Alert Level WARNING.

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


Status of the ash cloud can be found at the Alaska Aviation Weather Unit website at http://aawu.arh.noaa.gov/

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.
