I've always loved conspiracies.
Back before there were search engines, I'd frequent weirdo bookshops and buy tons of breathless tomes, authored by fakes, liars, and also True Believers.
If there's a conspiracy originating before 2000, chances are I have at least one book on it.
@countZZero oh I know HAARP exists.
I'm doubtful about it being able to trigger 7.8 earthquakes, though...
