Actually, I think that the area of the Asian tsunami was much more densely populated. When I was in Chenai I saw the lines on the sides of the buildings where the water reached. I think there are more people in Chenai than in Portland, Seattle, Tacoma, Spokane, Eugene, Yakima, Richland/Kennewick/Pasco combined, and that's just one city affected by that Tsunami. My guess is that they don't really have a clue how many people died because so few people don't have an actual address. Also, if your entire family and all your friends disappear overnight...who reports you as missing?

Coincidentally, I was sitting on a beach in Mexico sipping margaritas when that quakenami struck. That was a little un-nerving.

That is a good point.. but, the wave here would roll down the ENTIRE west coast, hawaii, up through The Canadian coast, and Alaska. How high a wave would it be by the time it got to San Francisco and Los Angeles? I don't know.. but it would be traveling several hundred miles an hour.

It would suck. A lot.

Also a good point. Regardless of where it happened, there would be plenty of suckage to go around for sure. Just for gits and shiggles, I looked up the population of Chennai and LA. 9.9mil vs 3.9mil respectively.

East coasters only need to worry about that landslide in the Canary Islands.

Imagine a 200 foot wall of water hitting NYC...

But you might have to worry about having AN address.

I didn't read the link, but it sounds like old news. There is a 300 year pattern, and 2000 was 300 years since the last. I'm planning on heading to Racer X' s house, but he's probably heading to mine. We're illprepared.

Living at the south end of the Cascadia "zone" and the north end of the "san andreas" zone, and west of the Gorda plate "triple junction"... this is not news, really.

The Cascadia zone is capable of 9-point quakes, along HUNDREDS of miles of the subduction fault at once. Think Indonesia 2004, only bigger and more populated.

If a quake like that happens, and you hear about it on the radio, and you're near a coast anywhere on the pacific rim? Get to high ground immediately...
A few years ago when house hunting, I passed up a place about 200 yards from the bay. This was one of the reasons (well, it being $20,000 higher than my budget was another reason).

Count on MINUTES before the wave hits the West Coast.

If it happens in our lifetime, well, it will be worse than anything this country hass seen in 250 years, wth the possible exception of the Civil War.
