There were incidents out west in Las Vegas and in some of the surrounding areas during the testing. There were also bigger problems in the Hawaiin islands with the testing in the pacific of the hydrogen bomb. These were hundreds of miles away from the explosion site. Street lights exploded and some communications equipment was knocked out. As this effect of a nuclear weapon was deemed super secret classified they made no mention of it in the Honolulu Daily.
An underground explosion will create an EMP but its in a small radious maybe 12-15 miles. Supposedly the ones that were exploded above ground out west were mounted on towers. They created an EMP but again since it had no height it was limited to maybe 75 miles or so. The idea is to put a nuclear warhead very high up overhead so that it gets the most spread on the shock wave. Once that shock hits the electrical wires it travels down the wires pickiing up speed and strength as it goes. Thats how the transformers will be knocked out and then when the massive surge comes off the wire and hits your electrical box your wiring is fried.
Perhaps you should do a little more research into the subject for yourself. We are prepared for this possible eventuality but you do not seem to be.
“We are prepared for this possible eventuality but you do not seem to be.”
Go ahead, prepare for an asteroid strike, too, if you want. I couldn’t care less, but this hysteria of ignorance about EMP is as annoying as it is to listen to the global warming nitwits.
