Episode 18 of the ongoing Halemaʻumaʻu eruption began at 10:01 p.m. last night when lava started overflowing from the north vent.
Currently the eruption is feeding lava flows that extend down the north vent spillway and a short distance onto the crater floor.
Emissions of SO2 gas are elevated, and during recent episodes have reached 20,000 to 50,000 tonnes per day or more. In addition, visitors to Hawaiʻi Volcanoes National Park and residents of adjacent areas may be exposed to Peleʻs hair and other small fragments of volcanic glass and tephra being carried in the plum.
Each episode of Halemaʻumaʻu lava fountaining since December 23, 2024, has continued for between 13 hours to 8 days, and episodes have been separated by pauses in eruptive activity lasting less than 24 hours to 12 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
