Non-nuclear EMP

Definition
A nonnuclear EMP weapon

"can . . . be designed to intentionally disrupt electronics, but these generally have short range and are not a threat to multiple assets."

Overview
"In addition to manmade EMPs, naturally occurring solar weather events of sufficient intensity can also cause electromagnetic impacts that can adversely affect components of the commercial electric grid, as well as other infrastructure such as satellites and undersea cables. The resulting impact of a solar weather event is commonly referred to as a geomagnetic disturbance (GMD)."
