Seriously though, the more likely impact would be from a potential "nuclear winter" as sulfur aerosols and air-borne particulates block out the sun for several months, and of course these particles will wreak havoc on respiratory systems and mechanical and electronic devices all over North America and presumably beyond. But, Seattle would basically still be standing.
Statistically-speaking you have more to worry about from being struck by a meteor than you do about Yellowstone.
The Oso landslide gave us a hint.
Seattle built on seven porous hills (one of which was leveled) is liquification alki.
Pervasive rain from Rainier to Renton brings the whole thing sliding down into the Salish Sea.
we have stringent building codes requiring seismic reinforcement. the new buildings might get red-tagged afterwards but they won't fall down during.
Yellowstone is EAST of us. 500 miles EAST. which way does the weather go? EAST.
@2: no. Oso =/= Seattle's hills. our hills had a thick sheet of ice moving over them for millennia. they're kind of PACKED DOWN now. only the steepest slopes (like Oso) are susceptible to slides, not "the whole thing".
More of a problem is the earthquake evidence that the Seattle Fault (under our stadia) could result in a 1-2 meter drop in the land, like it did once before, back in the mists of tiiiiimmme...
That would suck. But hey, ya makes yer choices, ya takes yer chances... Worried about natural disasters? Go live in Idaho or or something.
Where you don't want to be is in a old, unretrofitted structure built on landfill—or standing outside of anything brick.
In the worst case Ranier Eruption there are something like 130,000 people living in the lahar zones.
the religious have always preached the original Amageddon (the Rapture, 666, the Beast, horn of babylon etc)
but the educated, the left, and society in general loves to fantasize about any number of mega-disaster, societal collapse scenarios - the Red Scare (commies), nuclear winter, african killer bees, bird flu, ebola, Al Qauadea, bio-terrorism, climate change, aliens, asteroids, GMO food, vaccinations, non-vaccinations.
i've lived in several different /countries and have never seen anything remotely close to the end-of-times memes that we go thru.
Wrong. They said a tsunami would wreck anything west of I-5 AND south of Olympia. Think about it - we have a entire fucking mountain range between the Seattle Metro area and the Pacific Ocean. No tsunami is coming over the Olympics.
That said, the Sound will certainly swell as water works its through in and anything coastal will get flooded. But there won't be giant walls of water crashing into downtown. Damage from the actual earthquake is the concern for Seattle.
If the Puget Sound Area got a 10.0+ earthquake, the least of its worries is a 500 foot/150 meter tsunami... We would be talking a complete liquefaction of the ground, and huge drops of land. It would be the equivalent of set off a couple thermonuclear device under the Puget Sound Area. The strongest earthquake ever, was a 9.5 in Valdivia, Chile..
Everyone needs to stop taking their paranoia medication, remember the San Juan De Fuca Plate and Cascadia subduction zone is a still off the coast, not in Wedgwood..
The volume of water from a Cascadia subduction quake is immense. A movement of 1-2 meters along hundreds of miles of fault line creates a cavitation pocket with more power than a nuclear explosion "inside" of it. Distance is practically irrelevant since we're talking about geographical scale here. Any tsunami originating on this side of the Ring of Fire will hit this coastline with full force, and in roughly 30 minutes.
Wedgewood will be just as hard hit as Ocean Shores. On a global scale, there is simply no effective difference between the two.
