ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Thursday, June 29, 2017, 7:19 PM AKDT (Friday, June 30, 2017, 03:19 UTC)
53°55'38" N 168°2'4" W,
Summit Elevation 492 ft (150 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Following the explosive eruption that occurred today at 17:24 AKDT (01:24 UTC) and lasted about 20 minutes, seismicity as detected on neighboring islands has been quiet.
This event, though similar to previous ones in seismic intensity and duration, only produced a small cloud that extended about ten miles north of the volcano and had dissipated by about 18:15 AKDT (02:15 UTC). Since that time, we have seen no evidence of activity in satellite images.
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.
