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.

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.

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.

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.
Kilauea Message 2025-09-19 04:08:03 HST
Lava began erupting from the south vent forming a low dome fountain feeding a branching flow at 4:00 AM HST. North fountains do not appear to have changed significantly.

Current fountain heights are 700-800 feet (210-240 meters), the highest since episode 28 in July. The fountain remains inclined to the northeast at about 60 degrees, but less than episodes 31 and 32.

Episode 33 began this morning at 3:11 AM HST as fountaining increased along with a sharp increase in seismic tremor and rapid drop in tilt. Fountains are currently over 500 feet (150 meters) high and inclined to the north.

Continuous fountaining began at 2:44 AM HST this morning September 19th. Fountains are currently about 100 feet (30 meters) high and are feeding a flow on the crater floor. Episode 33 fountaining is about to start.
