December 9, 2025 — Sampling episode 38 at the summit of Kīlauea
Detailed Description
A USGS Hawaiian Volcano Observatory geologist collects clinker from a rubbly spatter-fed lava flow in Halema‘uma‘u crater produced during episode 38 lava fountaining. These lava samples are collected with permission from Hawaiʻi Volcanoes National Park and analyzed in the lab to better understand the magmatic system of Kīlauea. The scientist, who is about 6 feet (2 meters) tall provides a scale for how thick this lava flow is. USGS photo by C. Sealing.
