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.

The May 29 overflight provided updated aerial photographs of Kīlauea summit, covering the caldera floor and showing the current size of the water lake in Halema‘uma‘u crater.

During today's overflight of Kīlauea summit, both thermal and visual cameras were used to characterize activity. Comparing thermal (left) to visual (right) images of nearly the same view, you can see that the growing crater lake at Kīlauea's summit remains hot.

Instruments continue to collect vital data during workplace closures. Here staff perform maintenance on an eddy flux tower located within a phragmites wetland at the Cape Cod National Seashore. The instruments on this tower measure methane and CO2 fluxes related to plant and soil processes day in and day out for the entire year.

This series of maps compares aerial imagery collected prior to Kīlauea's 2018 summit collapse and the "Geologic Map of the Summit Region of Kīlauea Volcano, Hawaii" (Dutton and others, 2007; Neal and others, 2003)—created before Kīlauea's 2018 summit collapse—with aerial imagery collected after the 2018 summit collapse and a preliminary update to Kīlauea's summit ge
