URGENT UPDATE: Kilauea’s volcanic activity is intensifying, with a significant eruption expected between December 22 and 27, 2025. This follows nearly a year of episodic lava fountaining that began on December 23, 2024, marking a rare eruption style not seen in nearly 40 years.
The US Geological Survey (USGS) reports that the ongoing eruption has featured sustained high lava fountaining, lofting molten rock up to 460 meters (1,500 feet) into the air. This dramatic activity has reshaped the landscape around the Halema‘uma‘u crater, creating a new 42-meter (140-foot) tall hill and raising the caldera floor by 68 meters (223 feet).
Visitors to Hawaii Volcanoes National Park have witnessed breathtaking views, but officials warn of escalating hazards. The latest episode on December 6, 2025, highlighted the unpredictable nature of volcanic activity, featuring powerful fountaining that transitioned to a south vent, reaching heights of over 300 meters (1,000 feet).
“During high fountaining, life-threatening hazards exist within the closed areas of the park,” stated a USGS representative.
As of December 15, 2025, the eruption is paused but shows intermittent glow at the south vent, indicating renewed activity. The USGS maintains a WATCH alert level for Kilauea, emphasizing the need for caution among park visitors. No unusual activity has been reported in Kilauea’s East or Southwest Rift Zones, and nearby Mauna Loa remains at a NORMAL alert level.
The unique characteristics of this eruption allow scientists to monitor and document the activity in unprecedented detail. With modern technology, the Hawaiian Volcano Observatory (HVO) is able to provide real-time forecasts and closely track changes in volcanic behavior, crucial for public safety.
Field engineers are actively recovering buried monitoring stations and assessing tephra deposits to enhance understanding of the eruption’s evolution. Their work ensures timely and accurate data collection, which is vital for predicting future episodes.
WHAT’S NEXT: As the summit reinflates, officials anticipate another fountaining episode could begin shortly. Residents and visitors are urged to stay informed through official channels and adhere to all safety guidelines.
