Kīlauea Begins 31st Eruption Episode with High Lava Fountaining

The 31st episode of Kīlauea's ongoing eruption began on August 22, 2025, with lava fountaining from the north vent at Halemaʻumaʻu crater. Initial lava fountains reached approximately 100 feet high but are expected to grow larger, with past episodes producing fountains over 1,000 feet tall and eruptive plumes as high as 20,000 feet. The volcanic activity followed continuous spatter and lava overflows earlier that day, and the eruption remains confined within Hawaii Volcanoes National Park. Northeast winds at 15-20 mph are likely to carry volcanic gas and materials to the south and southwest of the summit caldera, potentially affecting air quality. Most eruptive episodes since December 23, 2024, have lasted about a day or less, separated by pauses of several days. Visitors are advised to stay informed of conditions due to possible hazards from volcanic emissions and falling debris.
