Following the short duration explosive eruption that occurred at 23:08 UTC (15:08 AKDT) August 27 and lasted about 2 minutes, satellite images show a small eruption cloud to about 26,000 ft above sea level drifting southeast. Since this event, seismicity and infrasound as detected on neighboring islands has been quiet and no lightning has been detected.
The National Weather Service Alaska Aviation Weather Unit issued a SIGMET for this eruption. Status of the ash cloud forecast can be found at the AAWU website at http://aawu.arh.noaa.gov/.
Bogoslof volcano remains at a heightened state of unrest and in an unpredictable condition. Additional explosions producing high-altitude volcanic clouds could occur at any time. Low-level explosive activity that is below our ability to detect in our data sources may be occurring. These low-level explosions could pose a hazard in the immediate vicinity of the volcano.
