AVO Pavlof YELLOW/ADVISORY - No significant activity in seismic, infrasound, or satellite data.

5:09 pm Eastern | U.S. News

Jul 23, 2017 20:29 - No unusual activity has been detected in seismic, infrasound, or satellite data. Web-camera views showed steam emissions from the summit. 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 ORANGE/WATCH - No significant activity in seismic, infrasound. Elevated temperature in satellite data.

5:09 pm Eastern | SciTech

Jul 23, 2017 20:29 - No significant activity in seismic or infrasound from Cleveland has been detected in the last 24 hours. Elevated surface temperatures at the summit were observed in partly cloudy satellite images over the past 24 hours. Web-camera views were obscured by fog. 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 »

Jul 23, 2017 20:29 - No activity was detected in seismic, infrasound, or lightning data over the past day. Nothing significant observed in partly cloudy satellite images. 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 ...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 | U.S. News

Jul 23, 2017 18:53 - 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, with continued activity on the coastal plain. These flows pose no threat to nearby communities. There have been no significant changes in seismicity levels across the volcano. At the summit, there was slight inflationary ground tilt and the lake level is roughly 25 m (82 ft) below the Overlook crater rim this ...read more »

AVO Great Sitkin GREEN/NORMAL - Seismic swarm detected. Activity is currently waning.

22 Jul 17:06 | SciTech

Jul 22, 2017 20:45 - An increase in seismic activity was detected at Great Sitkin starting with seismic tremor on July 21 16:17 AKDT (July 22 00:17 UTC). After about an hour, tremor transitioned to discrete earthquakes. Small earthquakes continue at present at a much decreased rate of several per hour. No anomalous airwaves were detected at the Adak infrasound array, and nothing was observed in satellite data above weather cloud tops, which were at about 10,000 ft asl. AVO continues to monitor Great Sitkin with a local seismic network, distal infrasound networks and with satellite ...read more »
