AVO Pavlof YELLOW/ADVISORY - No actvity observed.

15 Aug 17:07 | SciTech

Aug 15, 2017 20:19 - No activity was observed in partly cloudy satellite data. Pavlof was obscured by cloudy weather in web camera images from the past day. No significant activity has been detected in seismic and infrasound data over the past day. 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 Bogoslof ORANGE/WATCH - Heightened unrest continues. Seismicity elevated.

15 Aug 17:07 | SciTech

Aug 15, 2017 20:19 - A sequence of seismic events at Bogolsof began to be observed beginning at about 8:00 UTC on August 5 (MIdnight AKDT) and are continuing. Similar sequences have preceded eruptive activity at Bogoslof. In other cases, such activity died down with no major explosive activity. No infrasound or lightning signals have been detected in the past day. No activity has been observed in partly cloudy satellite data. The Aviation Color Code remains at ORANGE and the Alert Level remains at WATCH. Bogoslof volcano remains at a heightened state of unrest and in an ...read more »

AVO Cleveland ORANGE/WATCH - Unrest continues.

15 Aug 17:07 | SciTech

Aug 15, 2017 20:19 - Unrest continues at Cleveland Volcano. Elevated surface temperatures were observed in satellite data from this morning. The summit of Cleveland is obscured by cloudy weather in web camera images. No significant activity observed in seismic and infrasound data. 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 »

HVO Kilauea ORANGE/WATCH - Eruption continues at summit and East Rift Zone. Flows pose no threat to nearby communities.

15 Aug 14:05 | SciTech

Aug 15, 2017 17:39 - Activity Summary: Kīlauea Volcano continues to erupt at its summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow from Puʻu ʻŌʻō continues to enter the ocean at Kamokuna. Surface flows are active above the pali and on the coastal plain. These flows pose no threat to nearby communities. There have been no major changes in seismicity or deformation across the volcano. At the summit, the lava lake level has lowered slightly since it was measured yesterday morning, at which time it was about 28 m (92 ft) below the Overlook crater ...read more »
