South vent fountains are about 400 feet (120 meters) high. There has been about 31.5 microradians of deflation during episode 38, the largest recorded during this eruption. Approximately 13 million cubic yards of lava has been erupted.

Episode 38 has produced about 13,000,000 cubic yards or 10,000,000 cubic meters of lava over the past 6 hours. The north vent is not erupting, and south vent fountains are below 575 feet. There has been 24.5 microradians of deflation.

Just a note that if you are one of the dedicated observers that watch our instrument data, the "wiggles" in the tilt data were caused by the arrival of the teleseismic waves from the Magnitude 7 Hubbard Glacier earthquake in Alaska.

The high effusion rate of this episode is producing a very dramatic plume extending over 20,000 feet above sea level. There is misinformation being circulated in public that ground water is driving the fountains, but this is not true.

Fountains from the south vent are over 1000 feet high and inclined to the south. The summit has deflated over 16 microradians in 3 hours indicating that the effusion rate for this episode is very high.

The south vent fountain is now over 1000 feet (300 meters) high and inclined to the south. Hot pumice from this fountain destroyed the V3 streaming camera site a few minutes ago. Not a safe place for humans to watch. Thanks to you V3!

Kllauea is producing rare triple fountains this morning. Two are from the double vent in the north cone and one from the south vent. All of the fountains are between 400 and 500 feet (125 and 150 meters) high. Another first!
Kilauea Message 2025-12-06 08:59:43 HST
Episode 38 fountains began from the north vent at about 8:45 am HST and have rapidly progressed from 50-100 feet high to over 200 feet high by 9:00 am. Smaller fountains began from the south vent at 8:49 am HST and are over 100 feet high.

Rapidly increasing tremor and decreasing tilt indicate episode 38 is about to begin. Continuous precursory overflows have been feed a narrow lave flow into the center of Halema'uma'u since 3:37 am HST.
Kilauea Message 2025-12-05 20:50:57 HST
The north vent is a boiling cauldron of lava tonight and the south vent is spattering too. There have been 4 precursory overflows since just before 1 pm HST this afternoon and more overflows are expected before the fountain finale begins.
Kilauea Message 2025-12-05 12:56:52 HST
The first precursory overflow of lava from the north vent began at 12:52 pm HST and ended less than 2 minutes later. Inflation models indicate that the onset of episode 38 fountaining is likely to be December 6 or 7 with Dec 8 less likely.
