China, North Korea and others developing Super-EMP and other Electromagnetic Weapons, posing serious threat to civil society

The electromagnetic pulse commonly abbreviated as EMP, is a high-intensity burst of electromagnetic energy caused by the rapid acceleration of charged particles, can be produced by intense solar storms or by a nuclear weapon detonated high in the atmosphere. For example, solar geomagnetic storms (geomagnetic disturbances or GMD) create immediate and intense current surges that may disrupt electrical and electronic systems, potentially on a continental scale.
