August 22, 2025 — Monitoring episode 31 of the eruption at the summit of Kīlauea

Detailed Description

On August 22, USGS Hawaiian Volcano Observatory scientists hiked to the western rim of Halemaʻumaʻu crater to watch episode 31 of the ongoing Kīlauea summit eruption. Hiking across tephra fields from earlier lava fountaining episodes, renewed eruptive activity was evidenced by a stronger volcanic gas plume as well as heat shimmer above the crater. USGS photo by M.
