Thermal image of Halema‘uma‘u lava lake on November 16, 2021
This thermal image is looking west and shows the lava lake in Halema‘uma‘u, at the summit of Kīlauea. The active lava on the surface is limited to the west side of the lake, near the west vent. The eastern portion is solidified at the surface, with small ooze-outs often active along the lake perimeter. One of these ooze-outs has recently flowed a short distance onto the lowest down-dropped block. USGS image by M. Patrick.
