GEOMAGNETIC GROUND CURRENTS IN NORTH AMERICA: Space weather isn’t all about the sky. It’s in the ground, too. On April 16th, a severe geomagnetic storm caused electricity to flow through the rocks and soil of North America. Red zones in this animated map from NOAA show where voltages were greatest.
[I looked for worldwide reports, but it appears this current effect is centralized in North America.]
