Overview
- Hawaiian Volcano Observatory and the U.S. Geological Survey confirmed episode 48 began at 4:40 a.m. HST Monday when lava fountains from the north vent rose more than 200 meters.
- The National Weather Service in Honolulu issued an Ashfall Advisory for Hawaiʻi Volcanoes National Park and areas to the north and northeast and advised people to limit exposure and protect water catchments.
- Observers reported ash, centimeter-scale tephra, and strands of Pele’s hair at Uēkahuna overlook, along Highway 11 near Nāmakanipaio campground, and in communities including Volcano village, Mauna Loa Estates, and Ohia Estates.
- Lava flows have stayed inside Halemaʻumaʻu crater and the southwest side of Kaluapele with no significant activity on Kīlauea’s East or Southwest Rift Zones, and scientists are tracking seismic, deformation and plume data for any change.
- This episode continues an ongoing summit eruption that began in December 2024 and officials warn that fountaining may last hours while ash and volcanic glass fragments can cause respiratory, visibility and equipment hazards for nearby residents and visitors.
