Researchers have completed an 18-year study resulting in the first detailed three-dimensional map of electrical properties beneath the United States. With data from more than 1,800 magnetotelluric stations, scientists can now better predict how solar storms and geomagnetic disturbances might impact national power grids through underground geological pathways. This survey also provides insights into ancient landmasses and helps identify potential locations for mineral deposits and heat sources.
Main points:
- Creation of a 3D electrical resistivity map from the surface to the mantle.
- Improved risk assessment for power infrastructure during solar events.
- Identification of conductive materials like graphite and sulfide minerals in ancient formations.
