Wouldn’t a naturally occurring EMP be minimal and localized in scope, similar to a lightning strike?
Mother Nature can also pose an EMP threat with solar flares that cause a geomagnetic storm. These storms could produce an EMP affecting large areas of the US and can destroy major parts of the Electric Grid. Major EMP effects were observed in 1859 and 1921 and we have developed a more sensitive system and more sensitive equipment since then. Recent extended power outages due to geomagnetic storms have occurred and had significant economic effects.
