Volcano Watch: How hot is Kilauea’s summit water lake?

This thermal image of the water lake at the summit of Kilauea was taken from the western caldera rim on July 31. Warmer colors (yellow-orange) show higher temperatures, while cooler colors (blue) show lower temperatures. The image indicates that the maximum temperatures on the lake surface at this time are about 180 degrees. The cooler zones on the lake surface are patches of rising steam.

The recent first anniversary of the appearance of water at Kilauea’s summit is a reminder of how much has changed since the end of the 2018 eruption and summit collapse.
