The project looks at ground electric fields in the northwestern U.S. "There is a similar risk from man-made geomagnetic disturbances caused by electromagnetic pulse (EMP) weapons that resemble natural space weather events, although with even greater intensity and more concentrated local impacts," he said.Īt the 2017 American Geophysical Union Fall Meeting, Schultz will present recent research that examines a real-world example of 3D mapping of the crust and mantle of the contiguous U.S. Schultz underscores threats from possible attacks as well. Space weather is the flow of electromagnetic radiation given off by the sun, including extreme events such as coronal mass ejections that can intersect Earth's orbit, impacting electric fields on Earth. build resilience against space weather on critical infrastructure such as power grids." The EarthScope Magnetotelluric Transportable Array, part of the USArray, is an observatory of instruments that measures Earth's naturally occurring electric and magnetic fields. "EarthScope is materially helping the U.S. "A big induced current in power-transmission lines that takes down high-voltage transformers would be a major disaster," Schultz said.
