Let’s hope such an EMP solar blast will not happen again as it could very well destroy a good portion of the population. You may find a good description of just such an event many millennia’s ago at a web site by the name of Viewzone Magazin amongst many other interesting articles.
“Let’s hope such an EMP solar blast will not happen”
It is inevitable unfortunately. 100k years out, 300 years away... we don’t know when. Earthquakes, weather systems, cosmological events. If you haven’t read a up-to-date Earth Sciences textbook, they’re available and they’re very reasonably priced used. It’s fascinating reading and it good refresher of the dynamic planet that we inhabit.
