Portions of the now east coast of 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. (Edgar Cayce 1152-11 August 13, 1941)

Blue Ridge Georgia is located about ten minutes drive from the Tennessee border and is very clearly in Northern, not Southern, Georgia - so according to Cayce will remain above water.

As of this writing, there is no evidence for significant subsidence of southern coastal South Carolina and Georgia, despite this Cayce-reading forecast. (p 104 Coming Earth Changes, The Latest Evidence, by William Hutton 1996)
