Overview
- The eruption began at 4:15 p.m. on May 25, with lava fountains from the north vent exceeding 1,000 feet and the south vent later reaching around 800 feet.
- Lava flows remained confined to the floor of Halemaʻumaʻu crater within Hawaiʻi Volcanoes National Park, avoiding any impact on nearby communities.
- This event marked the 23rd summit episode since late December, following a series of short-lived eruptions separated by multi-day pauses.
- The eruption sent an ash and gas plume at least 5,000 feet high, releasing sulfur dioxide, carbon dioxide and water vapor that can form vog downwind.
- The USGS Hawaiian Volcano Observatory maintains 24/7 monitoring and livestreams of Kīlauea’s activity and warns that additional eruptive episodes remain possible.
