Recent Volcano Updates from the U.S. Geological Survey Volcano Hazards Program

July 9th, 2026 20:54:40 EDT -0400 AVO Great Sitkin ORANGE/WATCH - Slow eruption of lava within the summit crater continues. Elevated surface temperatures and rockfalls detected.
Jul 9, 2026 19:28 - Minor seismicity were detected over the past day. Steaming and elevated surface temperatures were observed in high-resolution satellite views. The current eruption began in July 2021 and, since then, lava flows have filled most of the summit crater and advanced into valleys below. There have been no explosions at Great Sitkin Volcano since an event in May 2021. The volcano is monitored using local seismic and infrasound sensors, satellite data, webcams, and regional infrasound and lightning networks.
July 9th, 2026 20:54:40 EDT -0400 AVO Kupreanof YELLOW/ADVISORY - Seismic unrest continues.
Jul 9, 2026 19:28 - Low-level unrest continues with seismicity at low-levels. Cloudy satellite imagery obscures views of the volcano.There is no real-time geophysical monitoring network at Mount Kupreanof. The closest functioning seismometers are approximately 17 miles (27 km) to the east of the volcano as part of the Mount Veniaminof network. Mount Kupreanof is also monitored by satellite data, remote infrasound and lightning networks, and visual observations from pilots and mariners passing by the volcano.
July 9th, 2026 20:54:40 EDT -0400 AVO Shishaldin YELLOW/ADVISORY - Ongoing volcanic unrest continues. Degassing at the summit continues.
Jul 9, 2026 19:28 - Minor seismic and infrasound activity signals were detected at the volcano. Weak degassing plume from the summit crater with sulfur dioxide and steam emissions observed in partly cloudy satellite views.Local seismic and infrasound sensors, web cameras, and a geodetic network are used to monitor Shishaldin Volcano. In addition to the local monitoring network, AVO uses nearby geophysical networks, regional infrasound and lightning data, and satellite images to detect eruptions.
July 9th, 2026 20:54:40 EDT -0400 HVO Kilauea YELLOW/ADVISORY - Kīlauea volcano is not erupting. Forecasts based on summit inflation indicate another lava fountaining episode is likely between July 11 and 15.

Current forecast models suggest that lava fountaining episode 51 will occur sometime between July 11 and 15. No significant activity has been noted along Kīlauea’s East Rift Zone or Southwest Rift Zone.A summary of lava fountaining episode 50 is posted below.NOTE: Significant changes in activity between Daily Updates are posted here: ...

Jul 2, 2026 19:50 - No significant activity was detected at Taʻū volcano during the past month. The USGS National Earthquake Information Center reported no earthquakes of magnitude 2.5 or greater in the vicinity of the volcano. A Global Positioning System (GPS) instrument on Taʻū Island recorded no significant deformation.The FAGA broadband seismometer located on eastern Taʻū Island is currently out of service. The TAU broadband seismometer on western Taʻū Island remains operational.
