Interesting Article on The Cascadia Subduction Zone And What It Would Do To The Pacific Northwest.....
When the 2011 earthquake and tsunami struck Tohoku, Japan, Chris Goldfinger was two hundred miles away, in the city of Kashiwa, at an international meeting on seismology. As the shaking started, everyone in the room began to laugh. Earthquakes are common in Japan—that one was the third of the week—and the participants were, after all, at a seismology conference. Then everyone in the room checked the time.
Seismologists know that how long an earthquake lasts is a decent proxy for its magnitude. The 1989 earthquake in Loma Prieta, California, which killed sixty-three people and caused six billion dollars’ worth of damage, lasted about fifteen seconds and had a magnitude of 6.9. A thirty-second earthquake generally has a magnitude in the mid-sevens. A minute-long quake is in the high sevens, a two-minute quake has entered the eights, and a three-minute quake is in the high eights. By four minutes, an earthquake has hit magnitude 9.0.

WIKI Info on CASCADIA SUBDUCTION ZONE
(this was a link on drudge)
I just hope we'll be out of here before it hits.....
ReplyDeleteThank you for that. I never expected such a well-written article on the subject, free from political agenda, by the New Yorker.
ReplyDeleteHad it been the NY Times, I feel certain they would have explained how Fukushima was due to fracking, and then gone on to describe how a major quake in the Cascadia Subduction Zone would cause a plague of locusts and be the fault of Bush (take your pick). Or the Christian Right. Or the Second Amendment.
Living in SW Montana, I wonder what seismologists/geologists think about such a quake's affect upon the Yellowstone "super-volcano" zone, if any.
I thought of that last night when I read the article. I remember watching the animation of what that supervolcanoe eruption would look like. I'm sure any huge quake in that area could awaken it. I also have read about the "long run-out" landslides of Hawaii and other islands. The tsunamis created are HUGE. Interesting stuff for sure. Maybe some good post material coming up :)
DeleteMother Nature will not be curbed. Ask The Goracle he'll claim it's the fault of global warming. I'm thinking God is really, really PO'ed right now so the coming devastation is no surprise to me.
ReplyDeleteI live right next to this and am literally 5 minutes from I-5. I see two volcanoes every day on my way to work and have to drive right next to the Columbia river, the biggest river West of the Mississippi, with 6 or 7 Dams upstream.
ReplyDeleteIf it hits I am a fucked duck.
I visited Mt. St. Helens about 10 years ago and was in AWE at the devastation still present after 20 plus years. I can't imagine it during the eruption and in the weeks after.
