Episode 12 of the ongoing Halemaʻumaʻu eruption began at 7:30 a.m yesterday with sporadic small lava flows alternating between the south and north cones. The transition to continuous fountaining started at 2 p.m

The first morning lava flow came from the south vent and lasted for approximately 20 minutes. It was followed by another sluggish flow from the north vent that lasted for about 12 minutes. Small fountains within the south vent fed a third small flow beginning at about 12:45 p.m which continued until 2:00 p.m.when fountaining began at the north vent.

Inflationary tilt reached just over 10 microradians since the end of the last episode; nearly balancing out the amount of deflationary tilt during episode 11. Seismic tremor began increasing and tilt at UWD switched from inflation to deflation at 2:00 p.m. HST, at the same time fountaining began.

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 from 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.
