AVO Cleveland ORANGE/WATCH - Brief explosion this morning. No ash detected.

6:37 pm Eastern | U.S. News

Aug 22, 2017 21:09 - Unrest continues at Cleveland Volcano. A roughly one-minute long explosion occurred this morning at 10:43 AKDT (18:43 UTC) that likely removed all or part of the lava flow observed on the floor of the summit crater in satellite data yesterday. The explosion signal was detected in seismic and infrasound data. Elevated surface temperatures at the summit also were observed in satellite data today, prior to the mid-morning explosion. Nothing of note was observed in web camera images throughout the afternoon and early evening yesterday. Cleveland volcano is monitored ...read more »

AVO Bogoslof ORANGE/WATCH - Unrest continues. Lava dome present in intra-island lake.

6:37 pm Eastern | SciTech

Aug 22, 2017 21:09 - Unrest continues at Bogoslof Volcano. Some minor explosions were detected in infrasound (air pressure) data this morning at about 4:10 AKDT (12:10 UTC), but no significant activity resulted. Satellite data obtained today indicates that the lava dome within the intra-island lake just west of the 1992 lava, has grown to about 525 feet (160 m diameter) since August 20. The presence of a growing mound of lava has heralded the end of several past eruptions of Bogoslof. However, during some eruptive periods, lava effusion has been followed by additional explosions and dome ...read more »

AVO Pavlof YELLOW/ADVISORY - No actvity observed.

6:37 pm Eastern | U.S. News

Aug 22, 2017 21:09 - No activity observed in mostly to partly cloudy satellite and web camera images. 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 »

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

3:35 pm Eastern | SciTech

Aug 22, 2017 19:21 - Activity Summary: No significant change. 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 is flowing into the ocean at Kamokuna. Surface flows are active above the pali and near the base of the pali on the coastal plain. These flows pose no threat to nearby communities. The summit lava lake is about 35 m (115 ft) below the rim of the Overlook crater this morning. There have been no major changes in seismicity or deformation trends across the volcano. Summit ...read more »

AVO Bogoslof ORANGE/WATCH - Unrest continues. Lava dome present in intra-island lake.

21 Aug 17:05 | U.S. News

Aug 21, 2017 19:41 - Unrest continues at Bogoslof Volcano. No significant activity has been observed in seismic or infrasound data over the past day. However, satellite data obtained today has confirmed the presence of an approximately 125 m diameter lava dome within the intra-island lake just west of the 1992 lava dome. A cold volcanic cloud also was observed in satellite data this morning extending about 33 miles (55 km) south of Bogoslof Island and likely represents the steam plume issuing from the lava dome. The Aviation Color Code remains at ORANGE and the Alert Level remains at ...read more »

Light degassing from the summit was observed in web camera images throughout the afternoon and early evening yesterday. No significant activity observed in seismic and infrasound data over the past day. 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.
