EMPs were first discovered during the testing of nuclear warheads back in the 1960s, the most famous of which was known as Starfish Prime. The atmospheric detonation over the mid-Pacific Ocean caused tremendous electromagnetic energy to be felt 900 miles away in Hawaii, knocking out street lights, setting off burglar alarms, and damaging microwave communications.
