Thermal map of Kīlauea summit

This thermal map was constructed from 1008 images collected by a thermal camera during a helicopter overflight on August 22, 2019. The hottest features in the caldera are the numerous small fumaroles in Halema‘uma‘u, and these areas have temperatures up to 200 degrees Celsius (392 degrees Fahrenheit). The pond of water at the bottom of Halema‘uma‘u also stands out, and has a surface temperature of approximately 70 degrees Celsius (158 degrees Fahrenheit). The light grey areas in the upper left and lower right corners of the map are regions not covered by the thermal map, and show a shaded-relief basemap.
