August 25, 2025 — Sampling episode 31 tephra and lava in Halemaʻumaʻu at the summit of Kīlauea
Detailed Description
On August 25, 2025, USGS Hawaiian Volcano Observatory field crews sampled lava and tephra from episode 31 during a morning monitoring overflight of Kīlauea summit. Samples from the episode will be later 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.
