AVO Cleveland ORANGE/WATCH - No significant activity observed in seismic or data data.

6:05 pm Eastern | U.S. News

Feb 20, 2017 21:54 - No significant activity was observed in mostly cloudy web camera and satellite views over the past day. No significant volcanic activity has been detected in seismic or infrasound data over the past 24 hours. The presence of the recently emplaced lava dome within the summit crater may act to block the vent, resulting in reduced or restricted gas emissions which may lead to explosive activity with little to no warning. Cleveland volcano is not monitored with a real-time seismic network and this inhibits AVO's ability to detect unrest that may lead to an explosive ...read more »

AVO Bogoslof RED/WARNING - Elevated state of unrest. Explosion at 2:08 UTC with cloud to 25000 ft

6:05 pm Eastern | SciTech

Feb 20, 2017 21:54 - The eruption of Bogoslof volcano continues. The afternoon of 19 February, at around 17:08 AKST (02:08 UTC), an explosion occurred producing a cloud to around 25,000 ft asl which traveled south-east. The explosion was detected by seismic, infrasound, lightning and satellite observations. 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. Some previous explosions have been preceded by an increase in earthquake activity that allowed for ...read more »

AVO Bogoslof RED/WARNING - Volcano quiet again for the moment after eruption from 17:08 to 17:45 AKST today.

20 Feb 01:35 | U.S. News

Feb 20, 2017 05:48 - Following the series of short, explosive eruptions that started at 17:08 AKST this afternoon (02:08 February 20 UTC) and lasted until 17:45 AKST (02:45 February 20 UTC), seismicity and infrasound as detected on neighboring islands has been quiet. Satellite images following the activity showed a volcanic plume extending about 100 miles (160 km) to the southeast over Unalaska Island and the Pacific Ocean. The plume was visible in images through 19:00 AKST (04:00 February 20 UTC). AVO geologists on Unalaska Island described the cloud has having a white upper portion and ...read more »

AVO Bogoslof RED/WARNING - Significant explosive eruption and increase to Aviation Color Code RED.

19 Feb 22:34 | SciTech

Feb 20, 2017 03:07 - A significant explosive eruption began at Bogoslof volcano at 02:08 UTC on 20 February (17:08 AKST on 19 February). Seismic and infrasound data show a series of short-lived explosive pulses through 02:45 UTC; seismicity has been quiet since then. Recent satellite images show a cloud as high as 25,000 ft asl. Thus, AVO is raising the Aviation Color Code to RED and Alert level to WARNING for Bogoslof volcano. Winds are carrying the cloud from Bogoslof to the southeast, towards Unalaska Island. read more »

AVO Bogoslof ORANGE/WARNING - Increase in seismicity suggests eruption is likely imminent.

19 Feb 21:04 | SciTech

Feb 20, 2017 01:35 - Seismicity as detected on instruments located on nearby islands is elevated and increasing in intensity, suggesting that an explosive eruption is likely imminent. As of yet there is no confirmation of significant ash emissions detected by lightning, infrasound or satellite data. The Aviation Color Code remains at ORANGE and the Volcano Alert Level remains at WATCH.

The most recent explosive eruption from the volcano occurred this morning starting at about 9:56 AKST (18:56 UTC) and was observed by seismic, infrasound, and lightning data. Satellite images and pilot reports indicate that the resulting ash cloud reached as high as 38,000 ft asl. Winds carried the cloud northward from Bogoslof out over the Bering Sea. This morning's activity, which consisted of individual pulses as seen in seismic data, lasted until about 11:40 AKST (20:40 UTC). Since then, seismicity as detected on neighboring ...read more »

Feb 17, 2017 19:48 - A significant explosive eruption began at Bogoslof volcano at 18:55 UTC (09:55 AKST) today. Pulses of seismicity are continuing. Preliminary satellite data show an ash cloud, and lightning continues to be detected. Thus, AVO is raising the Aviation Color Code to RED and Alert level to WARNING for Bogoslof volcano. Winds are from the south and will generally carry the ash cloud north over the Bering Sea. Activity is ongoing and additional explosive events may occur.
