53°55'38" N 168°2'4" W,
Summit Elevation 492 ft (150 m)
Current Volcano Alert Level: WARNING
Current Aviation Color Code: RED
Following the explosive eruption that occurred today at 19:07 AKDT (03:07 UTC July 5) and lasted about 11 minutes, seismicity as detected on neighboring islands has been quiet. Satellite images show a small cloud was produced that drifted to the southeast at an altitude of 32,000 ft asl.. No additional emission from the volcano has occurred.
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.
The Aviation Color Code remains at RED and the Alert Level remains at WARNING.
Status of the ash cloud forecast can be found at the National Weather Service Alaska Aviation Weather Unit website at http://aawu.arh.noaa.gov/
