Geomagnetic Pulsations Driving Geomagnetically Induced Currents
Space Weather, 2021 Geomagnetically induced currents (GICs) are driven by the geoelectric field induced by fluctuations of Earth's magnetic field. Drivers of intense GICs are often associated with large impulsive events such as coronal mass ejections.

Prediction of geomagnetically induced currents (GICs) flowing in Japanese power grid for Carrington-class magnetic storms [PDF]
Earth, Planets and Space, 2021 AbstractLarge-amplitude geomagnetically induced currents (GICs) are the natural consequences of the solar–terrestrial connection triggered by solar eruptions. The threat of severe damage of power grids due to the GICs is a major concern, in particular, at high latitudes, but is not well understood as for low-latitude power grids.
