COMMUNICATION BREAKDOWN – HOW TO STAY IN TOUCH AFTER A HEMP ATTACK

HEMP-300x336Sources of EMP

The most common EMP comes from lightning strikes and normal power surges as equipment is turned on and off. Other natural causes, such as solar flares, can also create an EMP. In 1989 the entire electrical grid of Quebec was shut down in about 90 seconds due to a solar flare that hit on the opposite side of the earth.

Modern electronics with microchips are most susceptible, followed by older transistorized circuits. That’s why we have surge suppressors for computers and other sensitive equipment. But most will not protect against a nuclear EMP attack.

EMP damages electronics by overvoltage. The EMP induces an extreme voltage into the conductors of small integrated circuits, causing them to arc and break down. In other words, they get fried.
