OSU researchers complete map of Earth's subsurface using electromagnetic energy

Nearly 20 years ago, researchers at Oregon State University began leading an effort to collect information about the structure and evolution of the North American continent using electromagnetic energy. That effort is finally complete. The new map can be used to protect the electrical grid during extreme solar storms and identify geohazards. It can also help target locations for tapping natural resources, including geothermal power and critical minerals. Adam Schultz led the effort at OSU and joins us to explain what we can learn from a better understanding of the Earth’s geoelectric properties.
