United States - April 09, 2025 Hawaii Volcanoes National Park, Hawaii - This video captures stunning scenes from a helicopter overflight and a field visit by USGS Hawaiian Volcano Observatory geologists. They explored the crater rim to witness the lava fountaining during episode 17 of Kīlauea’s ongoing summit eruption. The lava fountaining created a massive outgassing plume that soared above the summit. It also fed a fast-moving lava channel flowing east across the Halema‘uma‘u crater floor. The visuals highlight the power and beauty of the eruption, showcasing the dynamic volcanic activity. The geologists’ observations provide key insights into Kīlauea’s behavior during this phase.
