Kīlauea’s 55th Lava Fountaining Episode Ends After 6 Hours

Episode 55 of the ongoing Kīlauea summit eruption began at 3:19 a.m. HST on October 17, 2026, and concluded at 9:03 a.m. HST. The event lasted approximately 5 hours and 44 minutes, with lava fountains reaching a maximum height of over 700 feet (220 meters) by 5:00 a.m. HST. All activity remained confined within Halemaʻumaʻu crater in Hawaiʻi Volcanoes National Park. This episode followed a period of continuous lava overflows that began on October 16 and marked the 55th fountaining event since the eruption began on December 23, 2024.

Kīlauea Summit Unrest: New Vents Open as Pressurization Defies Forecast

New fissures opened on the northwest wall of Halemaʻumaʻu crater on September 14, 2026, as Kīlauea’s summit remained highly pressurized. While scientists anticipated a major lava fountaining episode, the volcano instead produced prolonged precursory activity and new low-level vents. The USGS notes that the outcome remains uncertain, with possibilities ranging from continuous lava flows to a return to fountaining or new vent formation.

Kīlauea Precursory Phase Extends to Record 6.8 Days Before Episode 55

Kīlauea volcano remains in a prolonged precursory phase, now lasting 6.8 days, the longest since the current eruption began. While lava fountaining has not yet started, overnight spatter bursts at the north vent reached 35-70 feet high. The USGS Hawaiian Volcano Observatory states that inflation-based forecasting models are no longer valid, making the timing of Episode 55 uncertain. All activity remains confined within Halemaʻumaʻu crater in Hawaii Volcanoes National Park.

Kīlauea’s Irregular Recharge Delays Episode 55 Amidst Precursory Overflow

Precursory lava overflows at Kīlauea’s north vent began on September 7, 2026, prompting the USGS to raise the alert level to WATCH. However, the anticipated Episode 55 fountaining has not yet started due to irregular magma recharge. The forecast window for the next eruption has widened to September 7–10, with a secondary window extending to September 13 if deflation continues. All activity remains confined within Halemaʻumaʻu crater.

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.
