[quote=Anonymous][quote=Anonymous]Which land areas along the East Coast are particularly vulnerable to tsunamis?[/quote]

The nature of the coastline is such that the energy will dissipate on the long throw of the continental shelf, with 100's of km of shallow water.  There may be a slight risk as you go south only because it is possible to have earthquakes that will generate tsunamis in the Caribbean.  But, I can not find any  records of runups more than 1 m from a distant earthquake.

There is another Tsunami hazard:  A meteorologically induced tsunami.  If a line of thunderstorms blows over the water at the tsunami speed, it can excite a tsunami.  This actually happened when a derecho (not the big 2012 derecho) came across the morning of June 13, 2013.  As the storm went off shore, the squall line, extending a few 100 km n-s, left the coastline.  By the time the storm hit the edge of the continental shelf, a noticeable wave was present.  At the shelf break, the forcing of the wave was lost (water was too deep for the velocity of the storm), and the wave was released.  It was observed from Rhode Island through North Carolina, and in Puerto Rico and Bermuda, though the wave heights were mostly on the order of 10-20 cm.  There was one location which recorded a 1.8 m wave:  BARNEGAT INLET, NJ.  There was no problems, because it was not high tide, and the weather was bad.

A similar phenomena swamps many cars at Daytona Beach in 1992.[/quote]
