I just heard a reputable scientist say it is unlikely we would have a tsunami on the east coast because the plates move horizontally not vertically.
The scenairo they are talking about has nothing to do with plate movement. The cause is half of a mountain (volcano)sliding into the ocean.
Drop a large rock into some deep water - same effect.
The bad news is - there is another one waiting to go off in the Pacific. The Big Island of Hawaii. Do some research on the "Great Rift" on that island. Huge hunk of the island sliding into the ocean.
The really bad news is that it is aimed at California. They were doing a geologic survey off the coast a few years back and found evidence that it has "fallen off" before. The slide went miles out. The calculations for the height of the wave created by that was mind boggling - 800 - 1000 ft., if I remember right.
So, when you play tourist - keep your jumping up and down to a minimum, ok?
