Kilauea’s Episode 55 Eruption Ends After Six Hours of Fountaining
Scientists said the eruption is episode 55 since Dec. 23, 2024, with lava fountains reaching 720 feet and a plume rising 25,000 feet.
On Saturday, October 17, 2026, Kilauea volcano began its 55th eruptive episode at 3:19 a.m. inside Halemaumau crater, within Hawai'i Volcanoes National Park, concluding abruptly at 9:03 a.m. after about six hours of continuous lava fountaining.
The eruption followed an unusually long two-month pause since August 25, with scientists attributing the delay to shallow earthquake swarms in September and early October that opened new cracks in the caldera.
Lava from the north vent shot about 720 feet into the air, while the eruption plume rose to around 25,000 feet above sea level. Observers reported tephra and volcanic glass, known as Pele's hair, falling in downwind areas.
Following the eruption's end, Hawaiian Volcano Observatory officials lowered Kilauea's Volcano Alert Level from WATCH to ADVISORY and its Aviation Color Code from ORANGE to YELLOW. Officials warned volcanic gas emissions may remain hazardous downwind.
While all lava remains confined to Halemaumau crater, scientists continue to monitor the volcano closely for further developments. Experts indicated fountaining is unlikely to return for the next few weeks despite ongoing volcanic gas hazards.
