Anyone who's paid a bit of attention to trending Prepper/Survivalist fiction has noted quite a few books on electromagnetic pulse or coronal mass ejection events. Newsweek published this on their website yesterday, October 9th. The event is thought to have been at least 10 times as powerful as the Carrington Event of 1859. Weren't a lot of folks using electrical equipment in 744AD, but they mentioned potentially trillions of dollars in damage, and outages lasting months. They're such optimists! Miyake events are very powerful CME's, and they've documented 9 of them in the past 15000 years. The most recent mentioned was over a thousand years ago. Can't ever happen again! Right?
With Mr. Putin rattling rockets, and "global warming" or "global cooling" or whatever they're calling it this week, some sort of event is very likely. Even a nearby lighting strike can cause great harm to our personal stuff, at least.
What can you do to mitigate the risk for yourself? Eh?
