May 29, 2020—Thermal map of Kīlauea summit

The May 29 overflight provided updated thermal images of Kīlauea summit, covering the caldera floor and showing the warm surface of the water lake in Halema‘uma‘u crater. No significant changes were observed in the surface temperature of Kīlauea's summit crater lake. Small hotspots are also present on the walls of Halema‘uma‘u due to fumaroles. This preliminary thermal map has some small areas of distortion, including some spots along the caldera rim. The surrounding area is shown by a 2018 satellite image.
