Episode 37 of the ongoing Kilauea eruption in Halemaʻumaʻu crater began at 2:30 p.m. today.

According to the Hawaiian Volcano Observatory, sustained lava fountains approximately 400 feet (120 meters) in height are erupting from the north vent, and fountain heights are increasing rapidly.

Past episodes have produced incandescent lava fountains over 1,000 feet (300 meters) high that produce eruptive plumes up to 20,000 feet (6,000 meters) above ground level.

All eruptive activity is confined to Halemaʻumaʻu within Hawaii Volcanoes National Park.

Episode 37 was preceded by small, sporadic spatter fountains and overflows that began at approximately 9:27 a.m. on Friday and alternated between the north and south vents.

Most episodes of Kilauea lava fountaining since Dec. 23, 2024, have continued for about a day or less and have been separated by pauses in eruptive activity lasting generally at least several days.

No changes have been detected in the East Rift Zone or Southwest Rift Zone.
