Researchers published the first detailed electrical conductivity map of subsurface structures beneath the continental United States.
The map integrates magnetotelluric measurements and geological datasets to visualize how rock properties vary with depth across regions.
Seismologists said improved conductivity models can refine earthquake hazard estimates by clarifying fault zone characteristics.
Geothermal developers may use the data to identify promising heat reservoirs for renewable energy projects.
The dataset will be shared with academic and government partners to support ongoing hazard and resource assessments nationwide.
Magnetotelluric imaging measures natural electromagnetic signals passing through Earth to infer conductivity variations linked to rock composition and fluids.
Earthquake hazard maps incorporate subsurface structure to estimate shaking intensity in regions with poorly understood fault geometries.
Geothermal developers use conductivity anomalies to identify permeable rock zones where heated fluids circulate near the surface.
The continental-scale map required merging datasets from regional geophysical surveys previously stored in incompatible formats.
Open data release of the electrical conductivity model will allow university researchers to refine local hazard assessments.
Earthquake early warning systems may incorporate subsurface conductivity data from the new continental map to refine shaking forecasts in seismically active regions.
A comprehensive subsurface electrical map of the continental US was published improving earthquake prediction and geothermal resource assessments.
