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 Precursory Activity Intensifies as Hurricane Lowell Obscures Summit Monitoring

Precursory lava overflows at Kīlauea’s summit continued on September 9, 2026, as the volcano approached a likely fountaining episode. The USGS Hawaiian Volcano Observatory (HVO) reported 29 intermittent overflows from the north vent, lasting between 15 minutes and two hours, with dome fountains reaching 15 to 30 feet. Two lava lobes formed, extending approximately one kilometer from the vent. Summit inflation remained unstable, recovering only 12.3 of the 12.7 microradians lost during the previous episode. HVO forecast episode 55 to begin between September 8 and 10, with a possible extension to September 13 if inflation stalls. Hurricane Lowell obscured webcam views, forcing scientists to rely on seismic tremor and thermal imagery for monitoring. The Volcano Alert Level remains WATCH, and the Aviation Color Code is ORANGE.

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.

Persistent Unrest: Kīlauea Volcano's Gas Escape Continues

The Kīlauea volcano in Hawaii is currently not erupting, with the alert level remaining at ADVISORY. Moderate seismic activity continues in the summit region, with a recent flurry of deeper earthquakes located below the summit caldera. Seismic activity has slightly declined in the upper East Rift Zone and Southwest Rift Zone. While there are no signs of an imminent eruption, scientists warn that eruptive activity could still occur in the near future with little or no warning. Sulfur dioxide gas emissions remain low, and the volcano's summit region remains unsettled with a high level of inflation and continued seismic activity.
