we're overdue biggtime!
I been sayin' it fo yers!
Seattle will be fucked for sure, washed away...
Growing up on the coast, we learned to always and foremost identify the path to high ground. A big enough tsunami may even reach 1000'+ elevation. Enough force would slam a huge assed wave into the coast range. I was acutely aware of the quake danger as I was hunting up there today and seeing all the Josephine Ophiolite structures made me think about what caused the uplift. At one time all that serpentinite, slate and sedimentry metamorphic rock was at the bottom of the sea. http://jersey.uoregon.edu/~mstrick/GeoTours/Josephine%20Ophiolite/JoOphiolite.html#Regional. Pix may follow tomarrow I found some really neat igneous flow mixed with ophiolite deposites that were forcibly thrust up at a 45-60 degree angle. The force that'd make a fault with that much uplift musta been catastrophically extreem. Granted, some of the structures were uplifted over time. But this one area I found had to have been explosively jutted up from really deep (serpentinite from the mantle and 45 degree fault).
The link i provided was exacly where I was at today and may return tomorrow. I may go back after the next rain and concentrate on the geology as tomarrow is the last day of hunting season and i'll be able to concentrate on the rock formations without checking under every single bush for an antler laden buck.
I watched this in a physical geography class a while back, cool stuff.
Hope the video works, cause I do more lurkin' then posting so don't know any better!
Looked just like the freeway viaduct in the last big frisco quake.
Most of the 6 ponters we feel are sub oceanic vulcanism created. They feel like a jolt like someone hit the building with a car. When the last one to hit San Jose happened (mid 90's?) I remember that one feelining like a rolling wave as opposed to a jolt. We felt it clear up here (360 miles) and it was totally different than the ones we feel from the submergerd volcanics off of Crescent City. This "big one" is accordingly 80 years past due if the 230 year cycle is correct. Seattle's cycle is estimated at 480 years. The whole subduction zone went at the same time in 1700.
I've felt 2 or 3 quakes, it's pretty weird.
My house is made of cinder blocks, it's going to fall to pieces in any decent quake. It's part of the reason I always keep my digital camera in a waterproof hard-case, so when the building collapses, my camera will be OK and I can take pictures and video of the aftermath
There's lots of stuff we're due or overdue for: The North Pacific quake and the Yellowstone Super Eruption, to name two right off hand...
Ever think that one could trigger the other at this point? That'd make a great scifi channel dissaster movie. "Shakenbake!"
Dramatic Video is dramatic! Lol @ 1:50: S..e..a..w..a..l..l....c..o..l..l..a..p..s..e..s
Didn't they design these things to withstand earthquakes? I thought that was standard building practice in all earthquake prone cities.
No, as a matter of fact they did not. When those were built the siesmic conciderations were completely different than they are today. Same goes with residential, commercial and institutional constructions. Todays codes are as stringent or more extreem than that of southern california's. the construction industry of the pacific northwest has been preparing for the "big one" for better than 15 years now. The coast has had renewed cautions placed on the hazards of tsunamis and signs like this are placed every 1/2 mile along highway 101:
That part of the simulation saying "no tsunami expected" took me by surprise.
The seawall construction was begun way back in 1916, times were a little different back then
I remember that day (goofus's post) with unusual clarity. I was living in Coos Bay and we were evacked to higher ground. good thing too. we lived at sea level down by the estuary and woulda been Sumatra'd if a wave hit. Seaside got hammered by the tsunami that day as well as Crescent City. http://www.usc.edu/dept/tsunamis/alaska/1964/webpages/index.html
Seaside would look like this now:
from this (them suckahs wouldn't stand a chance):
I've stood on that very street a time or two.
That area used to be a carnival that went all summer long, bumper cars, hammer, ferris wheel, tilt-a-whirl, go-cart track, arcades, you name it.
From the buildings, you can see why best western and shilo lobbied to have those places deemed immorral and to have them condenmed/removed.
I used to live in a house that used to be here before this hotel was built:
