I remember reading this stuff as a teen... in the early 70's... this from another forum poster elsewhere...

Edgar Cayce:

The first sign of this change in the Earth's core would be the "breaking up of some conditions" in the South Pacific and "sinking or rising" in the Mediterranean or Etna area. Cayce forecast that New York, Los Angeles and San Francisco would be destroyed. He said that (first) "the greater portion of Japan must go into the sea" at this time, and that northern Europe would be "changed as in the twinkling of an eye." In 1941, Cayce predicted that lands would appear in the Atlantic and the Pacific in the coming years, and that "the coastline now of many a land will be the bed of the ocean. Even many of the battlefields of (1941) will be ocean, will be the sea, the bays, the lands over which the new order will carry on their trade as with one another."

(after the Japan event)

"Watch New York, Connecticut and the like. Many portions of the east coast will be disturbed, as well as many portions of the west coast, as well as the central portion of the United States. Los Angeles, San Francisco, most of all these will be among those that will be destroyed before New York, or New York City itself, will in the main disappear. This will be another generation though, here; while the southern portions of Carolina, Georgia, these will disappear. This will be much sooner. The waters of the Great Lakes will empty into the Gulf of Mexico."

Cayce prophesied on reversals in climate, "so that where there has been a frigid or semi-tropical climate, there will be a more tropical one, and moss and fern will grow." By this time, he indicated, a "new cycle" would begin.

Cayce always said these events were determined by Man, ultimately and that if we changed our ways we could avoid them.
