February 3, 2025 — Tephra in Kīlauea's crater walls
Detailed Description
During a monitoring overflight on February 3, 2025, USGS Hawaiian Volcano Observatory crews had excellent views of Kīlauea's west crater walls, where tephra deposits have been exposed following the collapse of the summit in 2018. This image shows talus (rock debris from the crater walls) surrounding a triangle-shaped exposure of tephra that is many meters thick. USGS photo by K. Lynn.
