View from the south looking at the western, active part of the lava lake in Halema‘uma‘u crater at the summit of Kīlauea. Effusion into the lava lake is slow and steady with a few red-orange incandescent patches of lava visible within the flat black part of the lava lake. The perched margin of the active lava lake is visible around its perimeter. USGS photo by D. Downs.
