I have a faint memory trace that one of the future maps I've seen DOES follow some fault lines amazingly closely especially in the MIssissippi valley. I have no clue where or what that map was or how to find it.
On a serious note, events such as those depicted by the consequence of those maps would annihilate the entire population of the United States and obliterate civilization altogether. So, to be blunt, who really cares? If it's true then we will almost assuredly be dead, and if not we will be savages in a wasteland. If you and your fellow travellers think that this would achieve a glorious revival of some kind of fantasized religious heritage that is no less lunatic than the apocalyptic visions of their own accord.
I don't mean to sound so harsh, but that's what I think. Sorry.
