The Kīlauea Eruption's Reduced Lava Lake, Halema‘uma‘u Thermal Comparison

The eruption inside Halema‘uma‘u has been very quiet over the last month, and the size of the lava lake inside of the caldera continues to shrink. This thermal image comparison shows the diminishing area of active surface lava over the past month in Halema‘uma‘u, at the summit of Kīlauea Volcano. Over this time period, the activity has transitioned from a small lava lake to a series of weak surface flows near the western inlet. USGS images by M. Patrick.
