|(5) Previous Color Code:||RED|
|(6) Source:||Alaska Volcano Observatory|
|(7) Notice Number:||2017/A1|
|(8) Volcano Location:||N 53 deg 55 min W 168 deg 2 min|
|(10) Summit Elevation:||492 ft (150 m)|
|(11) Volcanic Activity Summary:||No further ash emissions have occurred at Bogoslof since Friday, December 30 at 22:30 AKST (07:30 UTC Dec 31). We are thus lowering the Aviation Color Code to ORANGE and the Alert Level to WATCH. Additional ash-producing eruptions could occur at any time, however, with no detectable precursors.
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 other islands for indications of volcanic activity. At present, these observations should allow timely detection of additional explosive events.
