Notes on High-Altitude EMP Impact Report


It is also not known how American society in general would react if massive infrastructure failures occur over a large region and for a long time.

Sections of interest:

Seems like most of the power grid vulnerability comes not from the power systems themselves (transformers etc.), but from the associated control systems.

it can be seen that the “brains” and communication systems of any modern power facility could be vulnerable to E1 HEMP


In this case we heard a “bang” associated with the damage, and further testing showed that a resistor on the circuit board was blown up
