The south vent drained back at 4:35 pm HST leaving only the north vent active. A new lava dome quickly rose within the south vent and vigorous overflows resumed at 4:38 followed by another drainback.

South vent dome fountain still around 30-40 feet (15 meters) high but about twice that in width as lava has completely buried the south cone. Tremor remains constant but UWD tilt is beginning to drop rapidly.

Major overflow from the south vent began at 4:21 pm HST.

Winds at the summit of Kīlauea remain light and variable making it difficult to predict how the eruption plume will behave if episode 40 high fountains begin in these conditions.

Precursory fountaining continues from the north vent and, with short pauses, from the south vent. Overflows from both vents are feeding a lava flow about 250-500 ft (75 m) wide that extends over a half a mile (1 km) into the crater.

Since 7 a.m. HST tremor has remained relatively constant at elevated levels. Tilt recorded on the UWD tiltmeter had been going down slowly since the south vent reactivated this morning but started to go up slowly around 10:00 a.m. HST.

Dome fountains about 50 feet (12 m) high continue to feed lava flows from both the north and south vents. The south vent flows are intermittent with short 5-10 minute breaks during drainback (drops 25 ft or 8 m) and refilling of the vent.

Both the north and south vents have been intermittently fountaining since about 7 am HST. The fountains are getting more vigorous indicating that more gas rich magma is involved. Tremor has increased but tilt remains flat at this time.

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.
Kilauea Message 2026-01-10 06:01:40 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.
Kilauea Message 2026-01-10 05:51:05 HST
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.
