No, of course not. I've seen this idea for several years now and it seems more wishful thinking on the part of some authors. They seem to take delight in the fact that the East Coast of the US could be washed away without realizing that a tsunami is a 360 degree affair.
Actually tsunami really aren't, as we saw in the Indian Ocean. They're quite directional depending on what initiates them. There was almost no wave ejected North or South from the Sumatran Quake.
