i always read the purpose of haarp was communication with deep sea submarines on the far side of the planet. the stuff it can do the crust and the ionosphere is some crazy shit tho. their power usage is also public record and people used to monitor it to see if it coincided with any seemingly massive natural disaster events and guess what? it did. many times. i'm too lazy to look it up and post links rn. but look it up for yourself.
