March 10, 2023 — December 2020 tephra at the summit of Kīlauea
Detailed Description
Close-up view of the pebbly, rubbly, and sandy texture of the tephra that formed in December 2020 when lava interacted with the water lake that was present at the base of Halema‘uma‘u crater at the time. Some of this tephra formed the island that then floated around the lava lake, and which is still present today. USGS photo by D. Downs.
