AVO Great Sitkin ORANGE/WATCH - Slow eruption of lava continues within the summit crater associated with low-level seismicity.

Oct 30, 2026 20:06 - Minor growth of the active lava dome within the summit crater was observed in satellite imagery over the past week.

The south flank of the dome is moving slowly southward and generating occasional small rockfalls.

While clouds obscured most satellite views of the volcano, minor steaming from the lava dome was observed in clear webcam views.

Seismic activity remains low with occasional small volcanic earthquakes and signals from minor rockfalls caused by lava flow growth.
