December 9, 2025 — Kīlauea summit overflight following episode 38 lava fountaining
Detailed Description
On Tuesday, December 9, USGS-Hawaiian Volcano Observatory geologists conducted a helicopter overflight of Kīlauea summit to survey changes from episode 38 lava fountaining a few days earlier. Scientists collected visual images for photogrammetry, thermal images, and collected lava samples from the caldera floor. They observed widespread deposition of tephra southwest of the vents from episode 38 fountaining, covering more of the closed portions of Crater Rim Drive. In this photo, outgassing plumes rise passively from the north and south vents. USGS photo by C. Sealing.
