One thing the article wasn't clear on was exactly how well the wave propagates into Puget Sound.

At least one good thing about the Indian Ocean Tsunami is that people finally understand what one actually is; previously there had been very little footage of one, besides some grainy black-and-white from Hilo Hawaii in the 1940s, and a bit from Japan more recently; documentaries and movies kept showing curling surfer waves from Hawaii and whatnot, and didn't convey it's basically a flood not a single curling wave. So I think people understand that even a 10 foot tsunami is disastrous.

I think that someone could make a layered map of how far inland a wave of x feet would go and draw a line, then an xx feet wave line, etc. The different geographical differences would need to be taken into consideration.

True, by far the most populous areas in Washington are on Puget Sound, not the Coast, and I'd assume a tidal wave would significantly if not totally be diminished by the time it got far into Puget Sound. Moreover, most of Seattle is on hills 100-400 feet above sea level.
