ELECTRIC CURRENTS ARE FLOWING THROUGH THE GROUND: Electrical currents surged through rocks and soil in the United States during last night's geomagnetic storm. Red zones in this map from NOAA show where the geoelectric voltages were highest: Peak voltages in the US midwest were near 5 V/km, more than 100x normal values when the sun is quiet. Fortunately, those peaks were only about 25% of what caused the Great Quebec Blackout in 1989. Power outages were therefore unlikely. The map, above, is a snapshot from a real-time display that takes into account the 3D conductivity of the Earth and ongoing geomagnetic activity. A computer at NOAA's Space Weather Prediction Center crunches the data to produce minute-by-minute estimates of electricity in the ground. These estimates help managers of public ultilities safeguard the power grid and keep power flowing to customers even during intense storms. |

Yes, isn't that something- I included this on my recent post below too. |
