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.

Three-dimensional geologic map of the Brady geothermal area, Nevada

The three-dimensional (3D) geologic map characterizes the subsurface in the Brady geothermal area in the northern Hot Springs Mountains of northwestern Nevada. We built the 3D map by integrating the results from detailed geologic mapping, seismic-reflection, potential-field-geophysical, and lithologic well-logging investigations completed in the study area. This effort was undertaken to investigat

Kīlauea Volcano summit eruption — thermal map GIF

ANIMATED GIF: This animated image file (GIF) includes a series of thermal maps—ranging from daily to several weeks apart—made from helicopter overflight thermal imagery of Halema‘uma‘u crater, Kīlauea summit.

Halema‘uma‘u eruption sequence Digital Elevation Models

HVO uses regular Kīlauea summit helicopter overflights of Halema‘uma‘u crater to create digital elevation models (DEMs) of the crater.

Lava Lake Depth March 4th

Data from a Kīlauea summit helicopter overflight on March 4th allowed for the calculation of the depth of the lava in Halema‘uma‘u crater.
