Episode 46 of lava fountaining in Halemaʻumaʻu began at the summit of Kīlauea began at 08:17 a.m. HST on May 5, 2026.
Ground-level sensors near the eruptive vents indicate slack winds at ground level. National Weather Service forecasts light and variable winds becoming southeast 5-7 mph this morning. This suggests that volcanic gas emissions and tephra may be distributed throughout the summit region and north/northwest of Halemaʻumaʻu.
USGS also notes that all eruptive vents and lava flows remain confined to Halemaʻumaʻu crater within Hawaiʻi Volcanoes National Park. Tephra fall is greatest within about 3 miles (5 km) of the vents, though lighter ash and Pele’s hair can travel much farther depending on wind conditions. Volcanic gas, including SO₂, can also create vog downwind.
Kīlauea has been erupting episodically since December 23, 2024, with most lava-fountaining episodes lasting a day or less. This livestream gives a multi-angle look at the build-up phase before the next major fountain event.
