That's off the coast.

The tsunami would have to cross the Olympic Peninsula heading somewhat
South or the flatter ground in SW Washington heading somewhat North.

But, as I used to say when at work after pointing this out, "if you
look at the Olympic Peninsula and see a wave standing a mile above the
peaks, evacuation would be a good idea". A sufficiently /tall/ wave
might make it, but it would be rather dissipated.

That leaves Puget Sound. To reach Seattle, it would have to enter a
small pipe called "The Straights of Juan de Fuca" going mostly East,
bounce off Bellingham to go mostly South, and bounce off Bainbridge
Island (now heading East) to reach Seattle. This would dissipate a lot
of energy. And water.

It would then have the option of going through downtown (flat
initially but backed by hills before reaching Lake Washington),
Ballard (coastal range, flat, Phinney Ridge, U district, the ridge to
the west of my house, our valley, the ridge to the east of my house,
more flatlands, Lake Washington.

Or it could force itself into an even smaller pipe (the Ship Canal),
devestate the lower parts of Ballard, the U District and the southern
end of the UW Campus, where the UW Hospital may still be located, Lake
Union, our valley (U Village and points south), and over-the-ridge
(Children's Hospital) and finally Lake Washington.

Lake Washington is quite large, but a small tsunami from the
earthquake would be possible and, of course, if enough water from the
big tsunami gets there, the level could go up. IIRC, up to 50' was
given at one time.

My estimates for a 50' rise in water level downtown were that the
waves would be lapping on the West side of 2nd Ave. For where I am,
since the serious slopes don't start until North of
Blakeley/Burke-Gilman trail, my guess would be the south edge of 55th.
The U District up to at least 45th, maybe Ravenna Blvd, would be under
water.

This would be very inconvenient. All my shopping is done in stores
that would be very very soggy. I would probably have to go up to 65th
to find bus service, when that is restored.

This is all speculative, of course. It is the nature of disasters to
be hard to predict in detail.
