Detailed Description

Lava fountains through the lava lake in Halema‘uma‘u, at Kīlauea's summit, create waves or ripples in the lake surface. The ripples are visible on the surface as thin crustal plates move apart and back together again as the wave motion passes by (like inner tubes in a crowded wave pool), creating a moving arc of increased glow. Video taken early Thursday morning, September 30, 2021. (Preview image is just the main fountaining source from September 30). USGS video by B. Carr.
