If a tidal wave hit the eastern US and the wave is 1000 ft how far will the wave travel inland?

Answer 1

Land forms slow them down considerably. The distance travelled inland is directly related to the change in elevation. It would be interesting to see how far inland this March 11th, 2011 tsunmai travelled past Antioch, California up the delta area.

Answer 2

Depends on where you're talking about. Some regions have high cliffs that would block most of the water. It also depends on how much energy the wave actually has after it breaks against the shore. A mile-high wave would break very far away from the coast, for example, and wouldn't go as far as a smaller tsunami. You'd also have to figure in the elevation of the different areas, so it'd be a complicated calculation. Here's a good link to an article about a 300-foot tsunami and its possible effect on the East Coast to give you an idea of how it's done.

Answer 3

A tidal wave hits the US coastline twice a day, as it does everywhere else in the world.

I think you mean a 'tsunami'.
