Volcanic Maps
The USGS Volcano Hazards Program enhances public safety and minimize social and economic disruption from volcanic unrest and eruption. We accomplish this by delivering effective forecasts, warnings, and information about volcano hazards based on scientific understanding of volcanic processes.

December 21, 2020—Kīlauea summit eruption reference map December 21, 2020—Kīlauea summit eruption reference map
Kīlauea summit eruption reference map showing the location of current and previous lake activity
December 21, 2020—Kīlauea summit interferogram 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.
December 21, 2020—Kīlauea summit eruption lava lake depth map December 21, 2020—Kīlauea summit eruption lava lake depth map
Kīlauea summit eruption lava lake depth map generated from December 21, 2020 imagery
December 21, 2020—Kīlauea summit eruption thermal map December 21, 2020—Kīlauea summit eruption thermal map
December 21, 2020—Kīlauea summit eruption thermal map constructed from aerial imagery
November 23, 2020—Kīlauea 2018 lower East Rift Zone lava flow thicknesses 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 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 September 20, 2020—HVO camera network map
Map of the USGS Hawaiian Volcano Observatory’s current camera network coverage.
May 29, 2020—Thermal map of Kīlauea summit 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 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 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 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.
