It seems no coast is immune to the threat of tsunami. For the Eastern United States, It is likely to begin on one of the Canary Islands, off the coast of North Africa. This would result from volcanic activity creating a huge underwater landslide in the Atlantic Ocean from which the waves would be generated. Estimates are waves as high as 200ft hitting the whole east coast from Boston to Miami and stretching inland for 20 miles.
