Kīlauea’s Halemaʻumaʻu crater resumed lava fountaining early Saturday at the Big Island summit. Scientists observed jets shooting tens of feet from the north vent and warned that volcanic gas and Pele’s hair could drift downwind. The eruption remains within Hawaiʻi Volcanoes National Park, though emissions may affect air quality downwind.
What HVO reported
According to the U.S. Geological Survey, Episode 38 began at 8:45 a.m. HST, producing lava fountains 50–100 feet (15–30 meters) high from both vents of the north cone. HVO scientists tracked rapidly rising fountains, seismic tremors, and ground deformation. The alert level remained at WATCH and aviation color code ORANGE as the summit was monitored.
Vog, Pele’s hair, and who’s at risk
HVO cautioned that high levels of volcanic gas, especially sulfur dioxide, can irritate lungs and eyes. Fragile strands of Pele’s hair can drift and accumulate on the ground. Strong winds may carry particles farther, so children, older adults, and those with respiratory conditions should monitor air-quality notices. Officials advise staying indoors and avoiding closed areas during advisories, according to Hawaii News Now.
Park access and aviation
All eruptive activity remains inside Halemaʻumaʻu crater in Hawaiʻi Volcanoes National Park. The U.S. Geological Survey said commercial airports in Hawaiʻi County (KOA and ITO) are not expected to be affected. Visitors should check the National Park Service site for current closures and safety guidance. Rangers advise following closures and staff directions, as vantage points and road access can change quickly.
Where this fits in the eruption cycle
The current summit eruption began on Dec. 23, and Saturday’s fountaining marks the 38th episode. The cycle alternates short fountaining events with pauses lasting less than a day to about two weeks. This pattern keeps lava inside the caldera but triggers air-quality advisories and forces park managers to adjust access. The Honolulu Star-Advertiser has reported on the episodes and their impact on communities and the park.
To stay updated, watch summit webcams and follow local news; Hawaii News Now captured live footage of Saturday morning’s fountains. Monitor official NPS alerts, follow health advisories if downwind, and avoid closed areas, especially if you have respiratory concerns.
