I've seen several maps like this of "future visions" by Edgar Cayce and other psychics (i.e., not credible). This video, among several others I've seen, give a plausible scientific explanation for how a massive earthquake could split the U.S. along the Mississippi River, and flood much of the east andwest coast.
Although the many videos on the subject (like this one) are all over the place about whether this would be (1) a short-sighted accident of over-mining, (2) an intentional planned destruction to de-populate the U.S., (3) or possibly a completely natural disaster that occurs every few hundred years.
