Intermittent vigorous fountains began at the north vent around 6:56 am HST as south vent activity diminished and stopped. The north vent fountains are feeding short lava flows on the floor of Halema'uma'u crater.

Precursory intermittent overflows and dome fountains are likely to continue prior to the start of episode 40 fountaining. Any significant changes in activity will be noted here or in the daily update around 9 am HST.

Lava began overflowing the south vent once more at 5:59 am HST after a 5 minute pause following a short drainback event. The drainback events produce small tremor spikes, but otherwise tilt and tremor remain flat nearby the vents.

Dome fountain fed flows resumed from the south vent at about 5:42 am HST. These are feeding a narrow flow that extends perhaps 500-1000 feet (200 meters) from the vents. Tremor and tilt remain level at this time.

The south vent began overflowing at 5:12 am HST this morning fed by a 10 foot (3 meter) high dome fountain for just under 10 minutes. Flows resumed again at 5:27 am HST. The smaller north vent overflows died down during this interval.

Overflows continue from the north vent with 5-10 minute breaks between flows. Tremor is constant with very little gas pistoning. The transition from intermittent to continuous precursory flows can happen quickly under these conditions.

The first north vent overflow began just after 8 pm HST and is continuing. The south vent last overflowed this morning and 3 times on Thursday. Lava flowed from the north east vent while the north west vent builds a small spatter cone.

USGS staff are visiting the V1 streaming video camera today to check the site. They are also testing a microphone that has the potential of adding sound to the camera. Sound is tricky due to wind noise, but V1 is the best site to test it.

Episode 39 ended at 2:13 a.m. HST on December 24, 2025 when south vent abrupted stopped erupting. North vent stopped erupting earlier at 2:00 a.m. HST.

The south vent reached a maximum fountain height of about 1400 feet at 9:30 pm HST. The north vent reached about 900 feet
at the same time. Currently the south vent is at 1000 feet and the north vent at 600 feet.

The south fountain has reached a height of 1400 feet (420 meters) while the north fountain has dropped to about 700 feet (210 meters). The lower level plume is moving southwest, but the plume about 20,000 feet is moving southeast.

South fountains are now 1250 feet (380 meters) high, while north fountains are 920 feet (280 meters) high. Effusion rates remain high and lava flows have covered about 10-20% of the floor of Halemaʻumaʻu crater.
