December 21, 2020—Kīlauea summit interferogram

This “interferogram” was created from satellite radar data acquired over Kīlauea Volcano on December 6 and 21 (at 6 PM HST each day). The colored fringes show ground deformation that occurred during that 15-day period. Each fringe is equivalent to about 1.55 cm (0.6 in) of ground deformation towards or away from the satellite.

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.

May 29, 2020—Updated aerial map of Kīlauea summit

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. The water lake has a surface area of approximately 25,000 square meters (6.2 acres), which is more than double the area measured in late December, when it was 11,000 square meters (2.7 acres).

Comparing Kīlauea's summit before and after the 2018 collapse

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 geologic map.
