The Appalachian mountains will be above the water line when all is said and done during this next pole shift, including the melting of the poles that will raise the oceans some 650-700 feet within a couple years after the shift. Where relatively isolated now, those living in these mountains will find themselves increasingly crowded with survivors who will be forced to move inland to escape the rising waters. The climate will remain temperate, and as the people of Appalachia have often been forced to live off the land, they should fare as well as any during these troubled times.
Karst topography, resulting from the erosion of limestone (which dissolves in water wash), creates caves and subsequent sinkholes when the area is distressed by fracturing of rock during earthquakes or the daily Earth wobble. The Appalachian area is riddled with such caves and escarpments. The predicted New Madrid adjustment will pull the N American continent at a diagonal so that rock adjustments will occur from the New England and Great Lakes regions all the way to southern Texas and thence to Mexico. Many new sinkholes will open up in those regions subject to limestone erosion. This does not alter the fact that the Appalachian mountains are high ground, fertile ground, and free from volcanic activity. Safety is a relative term. There is no "safe place".
No volcanoes will emerge or erupt in the Appalachian chain, either during the pole shift or in the events leading up to the pole shift. Why would the African Rift Valley have volcanoes, when it pulls apart, but not the southeast US? It is both the degree of rip and proximity to the plate border that determine this. In Africa, the plate is hung up at the Read Sea, snagged there such that the parts of the plate that fall below this point must tear away. This causes a greater thinning of the plate along the long rift, which starts at that point. The Appalachian chain is centered in the plate, so that as the stretch pulls down the plate as a whole along its eastern side, there is not a tear but a lowering action. Thus, no volcanoes.
