How much warning would west coast have of Tsunami?

[Cowperson]

Scientists say a giant rupture along the fault would cause the sea floor to bounce 20 feet or more, setting off powerful ocean waves relatively close to shore. The first waves could hit coastal communities in 30 minutes or less, according to computer models.

Seattle; Vancouver, British Columbia; and other big cities in the region probably would be relatively protected from deadly flooding because of their inland locations. But other, smaller communities could be devastated.

It's funny how terms like the sea floor "bouncing" or the world "wobbling" are used, in perhaps the most understatement kind of way possible! I mean if the the floor of the sea bounced can you imagine the results...

there would never be enough to evacuate those communities, thirty minutes warning would be enough time to say a prayer and hope for the best.

Look at Mount St Helen's eruption people refused to leave and they had ample warning.

The only thing that would save us from massive causualties is that we tend to have better home construction then they have in the third world.

Well, if severe enough, you could have some issues certianly on Van Isle.

Victoria, obviously, as well as Tofino/Uculet on the west side. Not sure about a place like Nanaimo on the east side of Van Isle, or Vancouver, being sheltered as it were, would be as affected (as the ater wall wouldn't crash down on those places as directly)....but then again, as low as Vancouver is, a 5 foot rise in water would cripple the city instantly, nevermind the rush up no North Van and the Sunshine higway to higher ground.

How long does it take before a someone realized that a earthquake happened out in the ocean, and how long for the Tsunamis to reach shore?

I don't know about that Captain. How far inland did the water go? With a half hour head start you could out-walk those waves by a good distance. We've heard a lot of stories from Asia of people out-running the water with no warning at all.

You might lose your house and everything you own and it could take a minute to load Granny in the car but half an hour is quite a while to at least get out of the way.

Gridlock would probably b e the worst thing to hinder escape over anything else. Perhaps the out run method if you don't have granny in tow would be best.

How much warning depends on where the earthquake happens.

Sorry to be a smartass, but it had to be said.

That's true no doubt for the big cities. I guess I was thinking of the smaller communities that could be devastated. ie you could get out of Sooke or Olympia in half an hour.

Wouldn't the best idea be to head out in a boat? Point it due west and hit the throttle.

good call - possible problems when docking afterwards, I bet, but a good way to avoid the wave and destruction of houses etc.

Half an hour really is a significant amount of time in a life and death emergency. Most of the people in Indonesia seemed to have zero warning. Assuming you're listening to your radio or you feel the quake, in half an hour, you can easily get to high ground, get up on your roof, and get all your family up there, too. Cement structures not directly affected by the earthquake seemed to do pretty well at withstanding the swells of water. Hotels, for example, where most of the videos circulating seemed to be filmed from. All you need is one building like that which everyone in town can get up on the roof of.

i guess that depends on the size of the wave and how tall they are as they move closer to land. Im not a tsunami expert by any means, but I would assume that it would be still rather large coming in, and Im not sure how many boats could withstand a 40ft wave.

The hundreds of fishing boats that went down off of Somalia suggests that this might not be the best theory. You would think that if you got far enough out, you'd hit the tsunami while it was still more of a swell than a wave, and then just ride it out. But it's hard to predict the direction of the waves. And also, the further out you get, the faster the waves are. Imagine that you're heading due west when a 40ft swell hits you from the southwest at 800 kmh.

There are lots of dead fishermen from the tsunami of a few days ago.

If I had 30 minutes, I would do a quick circle and figure out where the nearest hill higher than 100 feet might be, then start running there.

You might be able to run a bit quicker too, you know having 4 legs and all, plus there's the whole animal sense thing....

As long as there's a fire hydrant nearby, I'll be okay. I hate running on a full bladder.

I don't know, my gut feeling and low opinion of people in a panic capable situation tells me that a Tsunami coming inland would probably clean out the gene pool in that region.

Most people are too dependant on roads and vehicles, and would sit there leaning on thier horns as 800 feet of water rushed at them.

Then a certain percentage of people who made it to the hill would kill themselves in camping related accidents.

A half hour would also have people running around thier house and they tried to decide what to take with them.

that's very compassionate of you, captain.
