CORVALLIS, Ore. The major earthquakes that devastated Chile earlier this year and which triggered the catastrophic Indonesian tsunami of 2004 are more than just a distinct possibility to strike the Pacific Northwest coast of the United States, scientists say.
There is more than a one-in-three chance that it will happen within the next 50 years.
New analyses by Oregon State University marine geologist Chris Goldfinger and his colleagues have provided fresh insights into the Northwests turbulent seismic history where magnitude 8.2 (or higher) earthquakes have occurred 41 times during the past 10,000 years. Those earthquakes were thought to generally occur every 500 years, but as scientists delve more deeply into the offshore sediments and other evidence, they have discovered a great deal more complexity to the Cascadia Subduction Zone.
What weve found is that Cascadia isnt one big subduction zone when it comes to major earthquakes, Goldfinger said. It actually has several segments at least four and the earthquake activity is different depending on where a quake originates. The largest earthquakes occur in the north and usually rupture the entire fault. These are quakes of about magnitude-9 and they are just huge but they dont happen as frequently.
At the southern end of the fault, the earthquakes tend to be a bit smaller, but more frequent, he added. These are still magnitude-8 or greater events, which is similar to what took place in Chile, so the potential for damage is quite real.

Sea Tac Toe ping.
Odds are about 9 out of 10 that this guy will be dead in 50 years and nobody will get to tell him that his prediction was wrong.
I predict that sometime in the next 5 Years, Sen Byrd will die by natural causes or otherwise.
Hey! I'm a Prognosticator!!!
Old Sheets died years ago. He's animated by experimental electric implants based on studies with pithed frogs. Only problem is the pithed frogs had brain matter to work with.

What do frogs have to be pithed about?
We could be so entrenched in Communism by then that it may come as a relief.
That's a fact.
Somehow we will soon find out that Capitalism and big business is to blame for Global Shaking.
We're all gonna die!!!
Odds are about 1-in-3 that a megalomaniac will hit the floor in the Northwest corner of the White House in the next 2.5 years

I’d say this is credible, especially since these fault lines basically have to have earthquakes along their whole face to keep the tension under control.
If it happens in the south, it will also happen in the north.
I’ve been waiting....
Thanks, Sunny!
Nothing like a Reality Ping to bring me back to Reality!
(I’ll never get out of this world alive!!)
Pithing frogs is what you do to kill them quickly preparatory to dissecting out a muscle to experiment on in a saline solution. I did this for a living for a time. Didn’t like doing it, switched careers.
