Geology, Minerals, Energy, and Geophysics Science Center

Scientists with the GMEG Science Center work on issues related to geologic processes, mineral and energy resource potential, and past climate, primarily in the Western United States. The science staff includes Geologists, Geophysicists, Geochemists, Biologists, and Geographic Information Systems specialists located in Arizona, California, Nevada, Oregon, and Washington.

Primary Research Direction - What we do.

GMEGSC focuses on Geologic Mapping, Mineral Resources and Mineral Environmental Health, Landslide Hazards, Energy Resources, Earthquake Hazards, and Land Change Science.

Innovation - How we help.

GMEGSC hosts the USGS Innovation Center, which sponsors work with public and private technology partners to design, test, and bring into operation a new generation of technical and engineering tools to address urgent national natural science issues.

Disciplinary Expertise - How we do it.

GMEGSC utilizes Geologic Mapping and Tectonics, Geophysics, Economic Geology, Geochronology, Sedimentary Basin Studies and Energy Assessments, Landslide Hazards, Geomorphology, Paleoclimatology, and many more processes to complete our work!

Increased flood exposure in the Pacific Northwest following earthquake-driven subsidence and sea-level rise

Climate-driven sea-level rise is increasing the frequency of coastal flooding worldwide, exacerbated locally by factors like land subsidence from groundwater and resource extraction. However, a process rarely considered in future sea-level rise scenarios is sudden (over minutes) land subsidence associated with great (>M8) earthquakes, which can exceed 1 m. Along the Washington, Oregon...

Bølling-Allerød productivity in the subarctic Pacific driven by seasonal upwelling

The Bølling-Allerød deglacial event is marked by high diatom productivity and opal deposition throughout the subarctic Pacific. This opal could either constitute a strengthened biological pump and thus carbon sequestration, or a weakened biological pump and release of marine-sequestered CO2 to the atmosphere. We quantify silicic acid supply at IODP Site U1340 in the Bering Sea using...

Prospectivity modeling of the NASA VIPER landing site at Mons Mouton near the Lunar South Pole

We use a high-resolution digital elevation model and a numerical thermal model to produce a variety of inputs for a water-ice prospectivity model for the Volatiles Investigating Polar Exploration Rover (VIPER) landing site. These input data are maps of topography, surface slope, surface aspect, surface curvature, maximum temperature, depth to ice stability, permanently shadowed regions...

Life Cycle of Critical Minerals: A Balanced Approach to Meeting Our Nation's Resource Demands

Critical minerals are essential to the Nation’s economy and security. Demand for critical minerals is increasing, and it is essential to balance the societal need for these minerals with efforts to understand the effects of mining on other natural resources and to develop techniques to minimize these effects. The USGS Minerals Resources Life Cycle Integrated Science Team (IST) focuses on the life...

Geology of the eastern Piedmont and upper Coastal Plain along the Fall Zone, Virginia to Georgia

This USGS NCGMP Project aims to fill the void in geologic map coverage along the Fall Zone from southeastern Virginia to central Georgia, for critical mineral research, earthquake hazards, and interstate correlation. We are also forging strong cooperative ties within the NCGMP by combining resources across all three Program components by supporting Virginia Energy (Virginia Geological Survey), the...

Map of the Hurricane Helene landslide hazard estimates with the highest hazard being around the mountains.

2024 Hurricane Helene Landslide Hazards

Hurricane Helene produced widespread and damaging landslides. The USGS is mapping landslides to support our partners. This page provides information about the extent and severity of landslide impacts. Hurricane Helene made landfall in Florida as a Category 4 storm on Thursday, September 26th, 2024. The hurricane continued across the southern Appalachian Mountains producing record rainfall. This...
