The vent complex in Halemaʻumaʻu at the summit of Kīlauea that has been erupting episodically since December 2024 often features flames visibly emanating from the vents at night. These flames are thought to be the result of burning hydrogen gas, with the vent geometry being an important factor to allow the hydrogen gas to be efficiently ignited.

Episode 54 of lava fountaining in Halemaʻumaʻu at the summit of Kīlauea took place for about 9 hours on August 25, 2026. This timelapse video of the episode was taken by the V1cam, located on the northwest rim of the crater in Hawaiʻi Volcanoes National Park. The camera is a pan-tilt-zoom model so the perspective changes several times during the timelapse video.
