Episode 10 of the ongoing Halemaʻumaʻu eruption ended yesterday at 9:18 am after just under 13 hours of fountaining.

The north vent stopped erupting at this time after gradually declining in height.  Lava flows from this episode covered 75% of the floor of Halemaʻumaʻu within the southern part of Kīlauea caldera.

Deflationary tilt at the summit recorded about 6.5 microradians during this episode.  The end of the eruption was coincident with a rapid change from deflation to inflation at the summit and a decrease in seismic tremor intensity.

Each episode of Halemaʻumaʻu lava fountaining since December 23, 2024, has continued for 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. HVO continues to closely monitor Kīlauea and will issue an eruption update tomorrow morning unless there are significant changes before then.

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