United States - December 02, 2025 Hawaii Volcanoes National Park, Hawaii – Eruptive activity at the summit of Kilauea volcano on the Island of Hawaii remains paused as of December 2. USGS Hawaiian Volcano Observatory geologists on a monitoring overflight this morning observed a spattering lava surface deep within both the north and south vents in Halemaumau crater. Glow appeared in both vents on webcam imagery last night, along with weak spattering inside the north vent. Based on patterns of ground inflation since the end of episode 37 on November 25, models indicate that another lava fountaining episode is likely between December 5 and 9. This activity is confined to the summit of Kilauea volcano, within Hawaii Volcanoes National Park.
