September 24, 2025 — Sampling episode 33 lava in Halemaʻumaʻu at the summit of Kīlauea
Detailed Description
On September 24, 2025, USGS Hawaiian Volcano Observatory field crews collected samples from a cooled 'a'ā lava flow erupted during episode 33 (left half of photo in foreground) at Kīlauea volcano. This was part of a morning monitoring helicopter overflight of Kīlauea summit. The sample will be analyzed in the lab to track changes in the chemistry of erupted material and help scientists understand the processes driving the 2024-2025 episodic eruption. USGS photo by I.
