Continuous precursory overflows began from the north vent at 7:28 p.m. HST October 17. Fountains are 30-50 feet (10-15 meters) high. Tremor is increasing and tilt is dropping, episode 35 fountains should start soon.
Kilauea Message 2025-10-17 17:50:26 HST
Precursory overflows (31 total) of degassed lava continue from the south vent along with spattering in the north vent. The onset of episode 35 fountaining could happen anytime between now and Tuesday with Saturday or Sunday most likely.

15 lava overflow-drainback events occurred at south vent between 7:35 AM and 9:00 PM, Oct 16. More are expected as we approach episode 35 fountaining. Vigrous intermittent spatter continues at north vent.
Hawaiian Volcano Observatory Message 2025-10-16 10:22:12 HST
Small lava overflows from south vent occurred at 7:35 AM, 8:50 AM, 9:29 AM this morning. Each lasted ~12 minutes and ended with spattering and drainback. More overflows are expected as we approach onset of episode 35.

Nearly continuous strong glow is coming from both the north and south vents. Intermittent spattering in the north vent began just after dark. Seismic tremor indicates sustained tremor changed to irregular gas pistoning in the last 2 hours.

Short spatter bursts were observed from the south vent at 9:09 and 9:32 pm HST and at 9:29 pm HST from the north vent. These indicate that magma is high in both vents and spattering events should increase over the coming days.

There have been over 100 precusory overflows since the intial one at 9:43 PM HST September 28. Most happened yesterday, September 29, with nearly every gas piston resulting in an overflow. Since midnight there have only been 10
overflows.
Kilauea Message 2025-09-29 08:06:33 HST
There have been 8 gas piston overflows from the north vent overnight, with the frequency increasing this morning. Events last 5-10 minutes and are about 30 minutes apart. Episode 34 fountains are likely to start in less than 48 hours.
Kilauea Message 2025-09-28 22:01:27 HST
The first precursory overflow began at 9:47 PM HST shortly after magma was seen in the vent. Drainback of the pond and vigorous spattering was finished by 9:53 PM HST on Sunday September 2. This is the first gas piston event with a flow.

North vent fountains rapidly dropped and disappeared at 12:08 pm HST September 19. This appears to be the end of episode 33.
Kilauea Message 2025-09-19 04:13:43 HST
A pulse of lava flooded the south vent burying the cone at 4:05 AM HST. The pulse continued for 2 minutes and then rapidly drained back into the south vent ending the south vent eruption. The north vent fountains continue unchanged.
