I’ve read somewhere that the greatest risk for a Tsunami for the NC/VA coasts would be if the edge of the very steep underwater ‘shelf’ off the coast collapses out in the ocean. It would create a massive killer wave, and there would be almost no warning at all. I suppose the movement of land would be detected by seismic equipment, but by the time word got out, the beaches would already be receding.
Would be interesting if the water went into the Chesapeake just right, and did a ‘funnel-shot’ right up the Potomac. I’d imagine that cities constructed on top of low lying swamps along the river would be in grave danger. ;^) Not that I’d ever wish for such a thing.... (cough....cough)
