"The earthquake records seem very similar in both places," Goldfinger said. "[The two faults] are similar in 13 out of 15 of the last earthquakes, statistically showing that there is no difference in time, although there is a slight tendency for the Cascadia [fault] to go first."
"We think that when Cascadia ruptures, it causes stress that transfers to the San Andreas, and we think that within a few decades this triggers the San Andreas to go off. Timing is not exact; it could be hours, it could be years or it could be decades, but it is pretty close in [geological] time either way."
This fact that major fault systems have relationships with one another is a relatively recent discovery — only known for the last 15 years or so, according to Goldfinger.
"People used to think that fault lines were isolated from one another, but this doesn't make sense anymore," Goldfinger said. "Every piece of the earth is connected, so when one moves it is no longer surprising that the other pieces around it can be affected."
But how can this new knowledge about the West Coast fault lines be utilized?
The research allows scientists to understand the directivity of the two fault lines. For example, San Francisco can be affected very differently by earthquakes depending on whether the fault ruptures from north to south or south to north.
When an earthquake hits the Bay Area and travels from south to north, it has a tendency to move out to sea and therefore cause significantly less damage. However, if the quake goes north to south, San Francisco will be severely shaken.
The research provided by Goldfinger's team indicates that because the northern Cascadia fault triggers the southern San Andreas Fault, there is an increased likelihood that earthquakes will travel north to south, increasing damage.
Studying past earthquakes also gives scientists a geological timeline of when to expect the next one.
The last major earthquake occurring along the entire fault line, a 9 on the Ritcher scale, occurred in 1700.
According to Goldfinger, the northern part of the Cascadia fault has a major earthquake every 525 years. The southern part, however, has one every 278 years. Therefore, the southern part of the Cascadia fault is overdue for a major earthquake because it has been 308 years since the last one.
According to Goldfinger, earthquakes occurring in this area "Don't often go past 300 years, so one is about due."
"I've heard that an earthquake is overdue," said Jeff Berwick, a freshman in biology. "It is supposed to happen any time now. It will definitely be interesting to see what happens when we do have one."
Quick Facts
OSU professor Chris Goldfinger and his team conducted research on the history of earthquakes by examining underwater geological deposits in the southersn Cascadia subduction zone and the northern San Andreas Fault.
The last major earthquake in this region was 308 years ago
The northern Cascadia subduction zone ruptures on average every 525 years
The San Andreas Fault and Cascadia subduction zone have had earthquakes at the same geological time for the past 13 out of 15 quakes
Research has revealed earthquake history for specific faults from as long as 10,000 years ago
See this previous 2001 article A Prelude to the Big Big One? And big things are up again at Banda Aceh .. keep your eyes on Mount Merapi as well, as it appears to me that these are interlinked tec plates - if one tec plate moves, a corresponding one moves somewhere.

This doesn't make sense to me. Are you suggesting that BushCo is engineering these earthquakes? How?
Oh Dear, here we go again with the disinformation attack, DUH ! For the life of me, I could not find anywhere in the article where the author suggested Bush & Co engineered said earthquakes, therefore for a reader to suggest such an ascertion was made, one really has to question the reader's agenda.
Anyone with an ounce of grey matter between their ears, can, if they study reports from around the World, see that we are definately awaiting some enormous calamity of catacysmic proportions to happen, the only question is, WHEN.
To imply that the U.S. Administration is behind such an event, would be giving them abilities they can only dream about, and totaly ignoring mankinds actions and activeties on earth.
Or is it that they have a crystal ball and will take advantage of the chaos when the BigOne hits?
Now you may be finaly beginning to see the facts, I will ignore the crystal ball bit, however though, again, given all the scientific data being collected and collated by various countries around the World, the evidance is very clear, that we WILL be living thru such an event in the very near future, no crystal ball is neccessary, AND if you read the U.S. media, the administration has put in place laws to impose martial law under such circumstances.
Sure, you can ignore it all if you wish, it's your call, and your life, should you choose to through it away needlessly.
If there is to be a disaster to invoke MartialLaw, I doubt it will be this. I think they'll use nukes planted by "terrorists."
The only "terrorists" that plant such devices, emanate from the good old USA/UK, and a very young middle eastern country that claims God has promised them the whole place over there. (we have witnessed ample reports of such activeties in Iraq and the border with Iran )I would strongly suggest, you aquaint yourself with a little more knowledge of what's going on around you in your daily life.
It has been predicted, the U.S. will be cut in half by such an event, it has also been reported the caldera in Yellowstone is bulging at an unprecidented rate, now we hear of earthquakes near Oregon, clearly, whether anyone likes it or not, there IS something happening with the earth's crust, any Govt that would ignore such events, would be criminal. At the end of the day, we've already seen how criminal the U.S. Govt has been, and how far they are prepared to go in New Orleans. YEP, ignore it all at your own peril.

is what has brought America to its knees (CAnada, too)
Getting really educated was what was really necessary for our boomer generation - instead the way of life was to pour on more materialist GARBAGE and not save the planet as the full time agenda.
Now the Klusterfuck is upon us for real - worldwide starvation, the poor even poorer, the rich with more and power, the oceans full of garbage dumped not by us by the Department of Defense, the world's largest concentration camp in Gaza being genocided having people drink water with shit in it, women more oppressed than ever, children full of chemicals, nearly no information in th press, a nearly total breakdown in the food chain, many MANY animals gone, the bees are disappearing, the topsoil is eroded, the RULE OF LAW ignored, torture is ON THE TABLE when accountability is not, more drugs and prostitution institutionalized and by governments, people treat each other with disrespect and callousness, the MILITARY industrial complex takes precedence over people everywhere .. oh, I just could go ON and ON ....
So sure I come off as The Paranoid in this Moral Tale, right?
The insane are now the sane, those who look and care are the insane.
I posted it this as I have looked for Signs.
I find this highly troubling and I wonder how many people are aware of the massive social problems The Big One is going to cause.
I've done my job - I've alerted OpEd News readers and others to what I see.
What they do with the information is up to them - but imho denial and delusion (it ain't happening and it will be alright) mark this latest round of DANGER.
Everytime I get close to TRUTH, out come the plants and disinfo agents all over my back, so I am not surprised at the first comment in anyway. That someone actually took the time to deconstruct the negative comment does surprise me however. I've been posting WARNINGS here for a very long time.
This one has me very rattled indeed.
It's far better to keep control for the ruling class is they can point fingers at Mother Nature for social breakdown that that THEY cause than to have another synthetic terror event. Look at the world scenario from THEIR point of view, and you'll easily see that .. all information about these quakes is controlled by THEM - are you really so stoopid that you can't see the internet control that goes on?
Why do you think that they cut cables on the internet in the Middle East?
Who do you think controls the backbone of the internet - the pro human forces or a lot of elistest controllers ?
Watch the disinfo fly as the quakes continue .. note the supression of the news about them.
YOU DECIDE.
And I gotta say this - IF I WERE A GUY posting on OpEd News, this article wouild get a lot more comments and readers or IF I were known to argue about "democratic" politics and didn't post IMPEACHMENT in every article I write consistently
But because the global balance is SO OUT OF KILTER, I am just shoved aside in the cacophony of idiocy.
I've provided many many many "dots". I avoid like the plague making connections other people must make for THEMSELVES.
But I'll say this for free - eveyrone is doing the planet's young a grave disservice by staying immature and slothful.
I know what I know, I see what I see, I feel what I feel, I think what I think, and at least I know TRUE FREEDOM when it comes to the truth department.
I wish others, many others, could say the same.
I present my evidence and back up what I am saying. All else is SPECULATION and head garbage.

I watched the bullshit fly when the bridge collapsed in Minnesota. I protested that bridge in 1968! I was given a lead filled nightstick to my knee and am still crippled from it !! The bridge was constructed on US federal money improperly and opened just as Haiphong harbor incident happened.
I watch all these johnny come latelys whaft around with all their denial and it astonishes me, really.
When do these people finally CATCH ON ??
I've waited nearly 40 years to see ...
