Episode 39 of the ongoing Halemaʻumaʻu eruption is underway at Kīlauea | Maui Now

Episode 39 of the ongoing Halemaʻumaʻu eruption began at 8:10 p.m. HST on Dec. 23, according to an update from the Hawaiian Volcano Observatory. Sustained lava fountains approximately 100 feet in height are currently erupting from both north and south vents, with increasing heights.

Past episodes have produced incandescent lava fountains over 1,000 feet high that produce eruptive plumes up to 20,000 feet above ground level.  According to the National Weather Service, winds are blowing from the northeast direction, which suggests that volcanic gas emissions and volcanic material may be distributed to the southwest. 

• All eruptive activity is confined to Halemaʻumaʻu crater within Hawaiʻi Volcanoes National Park; commercial airports in Hawai’i County (KOA and ITO) will not be affected by this activity.
• Three Kīlauea summit livestream videos that show eruptive lava fountains are available here: https://www.youtube.com/@usgs/streams
• KPcam and MKcam provide views of the plume height for aviation purposes

Episode 39 was preceded by overflows of degassed lava that began at approximately 6:41 p.m. from the south vent and continued to increase in intensity until 8:10 p.m., when sustained fountaining began, according to the HVO.

Most episodes of Halemaʻumaʻu lava fountaining since Dec. 23, 2024, have continued for around 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. 

Kīlauea Volcano Alert Level/Aviation Color Code remain at WATCH/ORANGE. All current and recent activity is within Hawaiʻi Volcanoes National Park.
