Seismic Activity Persists at Alaskan Volcanoes

Buzzline

On September 9, 2026, the Alaska Volcano Observatory indicated that three volcanoes in Alaska continue to exhibit volcanic activity. Great Sitkin is currently under a WATCH status with an ORANGE aviation alert due to ongoing slow lava eruptions, minor earthquakes, steam emissions, and elevated temperatures at its summit. The eruption phase began in July 2021, leading to substantial lava accumulation in the summit crater. Shishaldin is at an ADVISORY level with a YELLOW aviation alert as it experiences low-level seismic movements and a gas plume at its summit. Kupreanof's status was downgraded to UNASSIGNED following a reduction in seismic activity and sulfur dioxide emissions. Vigilant monitoring is ongoing for all three volcanoes.

00:00Lava continues to erupt slowly inside Alaska's Great Sitkin Volcano.

00:04The Alaska Volcano Observatory says weak earthquakes were detected over the past day.

00:09Steaming and elevated temperatures were also seen at the summit.

00:13Great Sitkin remains at watch with an orange aviation color code.

00:17Its current eruption began in July 2021.

00:20Since then, lava has filled most of the summit crater.

00:24Lava has also advanced into valleys below the volcano.

00:26There have been no explosions at Great Sitkin since May 2021.

00:31Meanwhile, Shishildene Volcano remains at advisory with a yellow code.

00:36Weak seismic activity and a summit gas plume continue there.

00:39At Cuprina Volcano, seismic activity has dropped to very low levels.

00:44Its alert status was lowered to unisigned after declining unrest.

00:48Scientists continue monitoring all three volcanoes using seismic sensors, satellites, and webcams.
