A map of the continental US dotted with green and red circles of various sizes, indicating level of vulnerability of components of the power grid. Outlined areas covering most land east of the Mississippi, and the pacific northwest, could see system collapse from a large enough geomagnetic storm. Caption: 800 nT/min geomagnetic field disturbance at 50° geomagnetic latitude scenario. The regions outlined are susceptible to system collapse due to the effects of the GIC disturbance.

Telecoms will go down hard, and there’s a good chance your power grid will collapse.
Estimates in 2008 suggested as many as 130 million people in the US might experience power loss. In the most dire scenarios, full recovery was measured in years rather than months.
