Kīlauea Summit Opens New Vents as Pressure Rises

USGS reports that Kīlauea’s summit remains highly pressurized and new vents opened north of the Halemaʻumaʻu complex; while no major lava fountaining has started, precursory lava flows and minor spatter continue. Scientists outline possible outcomes including continued eruption from the new vents, a return to fountaining from existing vents, formation of additional summit vents, or magma intrusion toward a rift zone, with HVO daily updates if activity changes.

Kīlauea Edges Toward Episode 55 as Precursory Activity Extends

Kīlauea remains in the eruption’s longest precursory phase, with overnight spatter bursts at the north vent forming a spatter cone (35–70 ft) as tremor stays steady and summit inflation stays high; the USGS notes episode 55 fountaining is likely today or tomorrow if conditions remain favorable, with inflation above the episode 54 starting point. The Volcano Alert Level remains WATCH and Aviation Color Code ORANGE.

Kīlauea Eruption Update: Irregular Summit Inflation Persists Amid Ongoing Lava Overflows

USGS reports intermittent, low-level lava activity at Kīlauea's Halemaʻumaʻu summit with no net inflation; about 50 lava overflows since Sept 7 and a forecast window for episode 55 lava fountaining between Sept 10–11; summit inflation has been irregular since Aug 25, with tremor and SO2 emissions continuing as scientists monitor potential upcoming activity and possible gas/ash impacts.

Kīlauea Maintains Low-Level Summit Activity Ahead of Possible Episode 55

USGS HVO reports ongoing precursory, low-level lava activity at Kīlauea's summit in Halemaʻumaʻu with 29 north-vent overflows since Sept 7, fed by a 5–10 m dome fountain and forming two main flows that reached about 0.5 miles southwest and less than 0.5 miles northeast of the vent. Tremor persists, and summit reinflation has been unsteady since the Aug. 25 lava fountaining (episode 54), peaking Sept. 7 and then stalling. SO2 emissions run 1,000–5,000 t/day; trade winds are weak and the plume drifts southwest. Forecasters previously noted a Sept. 8–10 window for the start of Episode 55 high lava fountaining.

Kīlauea Poised for Next Eruption Phase as USGS Monitors Precursory Lava Activity

USGS webcams show precursory, low-level lava activity at Kīlauea's Halemaʻumaʻu summit starting Monday, with irregular inflation and brief dome fountains. The alert level was raised to WATCH and the Aviation Color Code to ORANGE in anticipation of a future high lava fountaining episode. By Tuesday morning, activity paused with summit deflation; ten overflows produced two lava lobes about a kilometer from the north vent. Reinflation remains irregular, and a September 8–10 forecast window for the next episode is likely if inflation resumes.

Magma Chemistry Hints at Potential Return of Taller Kilauea Lava Fountains

USGS scientists link rising lava fountain heights at Kilauea to magma differentiation and chemistry, especially MgO and olivine changes, suggesting a possible new growth phase as magma supply shifts; episode 44 brought a dip with new olivine, followed by renewed increases in episodes 46–48, amid a paused summit eruption and deflation that may affect timing of taller fountains.

New Kilauea Crack Sparks Intermittent Flames as Eruption Pauses

A new crack upslope of Kilauea's south vent is producing intermittent large flames while the eruption remains paused; the north vent glows, summit inflation continues, and a lava fountaining episode is forecast around August 8–12. USGS reports flames result from gas pistoning during tremor (about 3–5 times per hour) and maintains Advisory/Yellow alerts.

Kīlauea Pauses as USGS Forecasts Lava Fountaining Episode 51 for July 9–13

Kīlauea's summit eruption remains paused while inflation continues; USGS expects lava fountaining episode 51 to occur between July 9 and July 13, though the date could shift with inflation/deflation, and observers report persistent glow from the vents, low tremor, rising tilt, and SO2 emissions around 1,000–5,000 tonnes per day.

Kīlauea Volcano Nears One Year of Eruption, USGS Warns of Possible Next Week Blow

The Kīlauea volcano on Hawaiʻi is currently paused but is expected to erupt again between December 22 and 27, with ongoing monitoring indicating a new episode of high lava fountains. The volcano has been erupting episodically since December 23, 2024, with the next episode likely to occur within the forecast window, although the timing may shift based on inflation rates.
