November 23, 2020—Kīlauea 2018 lower East Rift Zone lava flow thicknesses

Final map of Kīlauea 2018 lower East Rift Zone lava flow thicknesses

September 23, 2020—Updated aerial map of Kīlauea summit

The September 23, 2020, overflight provided aerial photos of Kīlauea's summit that were used to construct an updated map.

September 20, 2020—HVO camera network map

Map of the USGS Hawaiian Volcano Observatory’s current camera network coverage. 

June 5, 2020—Subaerial extents of Mauna Loa lava flows from the past 200 years

Map showing the subaerial extents of historical lava flows from Mauna Loa. Lava flow hazard zones and districts of the County of Hawai‘i are also depicted.

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.

December 18, 2019, updated aerial map of Kīlauea summit

The December 18, 2019, overflight provided updated aerial photographs of Kīlauea summit, covering the caldera floor and showing the current size of the water pond in Halema‘uma‘u crater.

Thermal map of Kīlauea summit - December 18, 2019

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.
