May 26, 2025 — Kīlauea Tephra from Episode 23
Detailed Description
Episode 23 of the ongoing Kīlauea summit eruption in Halema‘uma‘u began with high fountains that deposited tephra outside the caldera to the southwest. Material was still molten as it fell on the landscape, evidenced by the fluid textures shown here. This clast, large enough to be called a volcanic bomb, is over 50 cm (almost two feet) long.
