Black and white thermal image of Kilauea summit

The December 18 overflight provided updated thermal images of Kīlauea summit, covering the caldera floor and showing the warm surface of the water pond in Halema‘uma‘u crater. A band of warm temperatures persists along the new cliff formed during the 2018 subsidence. The label "downdropped block" shows the large portion of the caldera floor that subsided, along with the Halema‘uma‘u region, during the 2018 eruption. The surrounding area is shown by a 2018 satellite image. This preliminary thermal map has some small areas of distortion, including some spots along the caldera rim.
