USGS Reports Stagnation of Kīlauea Eruption Vents
US · Published Sep 18, 2026
The USGS Hawaiian Volcano Observatory issued an update on September 17, 2026, confirming that all six new vents at Kīlauea's Halemaʻumaʻu crater have stagnated as of the previous evening.
Minor summit deflation began around 5 p.m.

Impact & Risks

The stagnation of the vents reduces immediate risks of lava flow, but the release of volcanic gases, including sulfur dioxide, remains a concern for air quality in downwind areas. The ongoing activity also poses risks to visitors and residents near the summit due to potential rockfalls, ground cracking, and other hazards. The area remains closed to the public.
