AVO Pavlof YELLOW/ADVISORY - Nothing observed in satellite data. Nothing detected in seismic/infrasound data.

28 Jun 17:05 | SciTech

Jun 28, 2017 20:23 - Nothing noteworthy was observed in cloudy satellite or web camera images today, and no unusual activity has been detected in seismic or infrasound data over the past 24 hours. The level of unrest at Pavlof can change quickly and the progression to eruptive activity can occur with little or no warning. We continue to monitor Pavlof closely and will provide any new information about the status of the volcano when or if it becomes available.read more »

AVO Cleveland YELLOW/ADVISORY - Nothing observed in satellite data. Nothing detected in seismic/infrasound data.

Jun 28, 2017 20:23 - Nothing noteworthy observed in cloudy satellite or web camera images today, and no unusual activity has been detected in seismic or infrasound data over the past 24 hours. Cleveland volcano is monitored with a limited real-time seismic network, which inhibits AVO's ability to detect precursory unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data.read more »

Bogoslof volcano remains at a heightened state of unrest and in an unpredictable condition. Activity can escalate quickly with additional explosions producing high-altitude (>15,000 ft) volcanic clouds with little to no detectable precursory activity. Some previous explosions have been preceded by an increase in earthquake activity that allowed for short-term forecasts of imminent significant explosive activity. Although we ...read more »

AVO Bogoslof RED/WARNING - Seismicity has declined. Ash emissions decreased below detection limit or ended.

27 Jun 11:04 | SciTech

Jun 27, 2017 14:53 - Explosive eruptive activity resumed at Bogoslof volcano early this morning with a roughly 14 minute long episode beginning at 11:17 UTC, June 27 (03:17 AKDT). The eruption produced a volcanic cloud that reached an altitude of 30,000 ft asl based on satellite data, prompting AVO to raise the Aviation Color Code to RED and Volcano Alert Level to WARNING. No infrasound was detected at networks from nearby islands, but the World Wide Lightning Location Network (WWLLN) detected lightning strokes associated with the resulting volcanic cloud. The volcanic cloud remains visible ...read more »

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

27 Jun 09:36 | SciTech

Jun 27, 2017 11:52 - A significant explosive eruption began at Bogoslof volcano at 11:17 UTC on June 27 (03:17 AKDT) as indicated in seismic and lighting data and is continuing. Although at this time there have been no satellite images or pilot reports received confirming eruptive activity, these monitoring data strongly suggest that significant ash emissions have occurred. Thus, AVO is raising the Aviation Color Code to RED and Alert level to WARNING. AVO is evaluating all data sources and will update this report as more information becomes available. read more »

AVO Bogoslof ORANGE/WATCH - Seismicity has declined. Ash emissions decreased below detection limit or ended.

26 Jun 23:09 | U.S. News

Jun 27, 2017 02:48 - Seismicity for the eruption at Bogoslof volcano at 00:45 UTC on June 27 (16:45 AKDT on June 26) remained elevated until 00:59 UTC (16:59 AKDT) and has since declined to background levels. The eruption produced a volcanic cloud moving northeast with an estimated altitude of 25,000 ft asl by satellite data, and a pilot reported a visible cloud at 22,000 ft asl. Given the lower altitude of the volcanic cloud and short duration of the explosion, the Aviation Color Code remains ORANGE and Volcano Alert Level WATCH. Recent eruptive episodes have produced multiple ...read more »

AVO Cleveland YELLOW/ADVISORY - Nothing observed in satellite data. Nothing detected in seismic/infrasound data.

26 Jun 17:06 | SciTech

Jun 26, 2017 20:43 - Recent observations of Cleveland Volcano suggest that unrest has declined and it is unlikely that eruptive activity is continuing, prompting AVO to lower the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY earlier today. Satellite observations have yielded no evidence for continuing lava effusion since June 7, and there have been no detections of anomalous seismicity or infrasound from the volcano since a brief explosion on Tuesday evening (May 16) at 19:17 AKDT (03:17 May 17 UTC).
