According to the Hawaiian Volcano Observatory, continuous lava fountains approximately 400 feet (120 m) in height are erupting from the northern vent, and the height of the fountain is increasing rapidly.
Previous episodes have produced incandescent lava fountains more than 1,000 feet (300 m) high that produce explosive plumes up to 20,000 feet (6,000 m) above ground level.
All eruptive activity is confined to Halemaumau within Hawaii Volcanoes National Park.
Episode 37 was preceded by small, sporadic splash fountains and overflows that began around 9:27 a.m. on Friday and alternated between the north and south vents.
Most episodes of Kilauea lava fountaining since December 23, 2024 have continued for about a day or less and have generally been separated by interruptions in eruptive activity lasting at least several days.
No changes have been observed in the East Rift Zone or the South-West Rift Zone.
