Maps

Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

December 22, 2020—Kīlauea summit eruption thermal map

December 22, 2020—Kīlauea summit eruption thermal map constructed from aerial imagery

December 22, 2020—Kīlauea summit eruption lava lake depth map

Kīlauea summit eruption lava lake depth map generated from December 22, 2020 imagery

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

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 thermal map constructed from aerial imagery

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).
