Color image of lava lake temperature

Detailed Description

View looking down at the September-October 2021 lava lake eruption of Halemaʻumaʻu from the F1 thermal camera located on the western rim of the crater at Kīlauea’s summit. Molten material appears as warmer colors of yellow, orange, and pink, whereas cooler material is represented by dark blue and purple colors. The left-hand image is from September 29, 2021, at 5:32 p.m. HST and shows that the lava lake has essentially repaved the floor of the crater with the exception of the central raft and part of the old west vent system. The right-hand image is from October 4, 2021, at 7:50 p.m. HST with noticeably darker blue/purple rafts present throughout the eastern part of the lava lake and with both the central raft and old western vent system having more exposed area.
