This photograph was taken from Volcano House Hotel, in Hawaiʻi Volcanoes National Park at around 11:25 a.m. on January 24, 2026, around the time that the USGS Hawaiian Volcano Observatory declared the start of episode 41 of lava fountaining at the summit of Kīlauea. At this time, the lava fountains from both the north and south vents at the western end of Halemaʻumaʻu were starting to increase in height and vigor. USGS photo by D. Downs. 

USGS Hawaiian Volcano Observatory scientists observed and documented episode 41 of the episodic Kīlauea summit eruption in Halema‘uma‘u. This photograph, taken from the Keanakāko‘i Overlook in Hawaiʻi Volcanoes National Park, shows lava fountains from both the north and south vents, with tephra falling in the foreground.

USGS Hawaiian Volcano Observatory scientists observed and documented episode 41 of the episodic Kīlauea summit eruption in Halema‘uma‘u. Lava fountains in both the north and south vents were active with maximum heights reaching 460-480 m (1500-1575 ft). Tephra fallout ranging in size from about 1-15 cm (less than an inch to 6 inches in diameter) reached the Keanakāko‘i Overlook in Hawaiʻi Volcanoes National Park, which the National Park Service closed due to hazardous conditions as tephra continued to fall during the episode.
