Lava fountain from Kilauea volcano today (image: USGS / HVO webcam)The 26th lava fountaining episode at the Halemaʻumaʻu summit crater began this morning, at approximately 1:40 a.m. local time on June 20, 2025. Lava fountains have been reaching more than 1,000 feet (300 meters) height and feed multiple lava flows covering the crater floor.The volcano observatory reports: "According to the National Weather Service, winds are blowing from the north direction, which suggests that volcanic gas emissions and tephra from the lava fountain may be distributed south of Halema'uma'u caldera. "Episode 26 was preceded by small, sporadic spattering and lava overflows from the north vent that began at approximately 11:26 p.m. and continued to increase in intensity until 1:40 a.m., when sustained fountaining began. Fountains from north vent are 800 feet (250 meters) high and feeding a lava flow at 1:55 a.m. HST. "Inflationary tilt reached just over 15.3 microradians since the end of the last episode. Seismic tremor began increasing and tilt at UWD switched from inflationary to deflationary at about 1:40 a.m. HST, about the same time lava fountaining increased in intensity. "Most episodes of Halemaʻumaʻu lava fountaining since December 23, 2024, have continued for around a day or less and have been separated by pauses in eruptive activity lasting generally at least several days."
