Sun and Moon Trigger Deep Tremors on San Andreas Fault
Daily Scientist ^ | Dec 25 2009 | Daily Scientist

Posted on 12/25/2009 8:37:22 AM PST by Brugmansian

The faint tug of the sun and moon on the San Andreas Fault stimulates tremors deep underground, suggesting that the rock 15 miles below is lubricated with highly pressurized water that allows the rock to slip with little effort . . .

They found the strongest effect when the pull on the Earth from the sun and moon sheared the fault in the direction it normally breaks. Because the San Andreas Fault is a right-lateral strike-slip fault, the west side of the fault tends to break north-northwestward, dragging Los Angeles closer to San Francisco.

"When shear stress on a plane parallel to the San Andreas Fault most encourages slipping in its normal slip direction is when we see the maximum tremor rate," Bürgmann said. "The stress is many, many orders of magnitude less than the pressure down there, which was really, really surprising. You essentially could push it with your hand and it would move."

In fact, the shear stress from the sun, moon and ocean tides amount to around 100 Pascals, or one-thousandth atmospheric pressure, whereas the pressure 25 kilometers underground is on the order of 600 megaPascals, or 6 million times greater . . .

Could it be that the sun & moon’s cycles and earth’s molten core also influence climate on the earth’s surface? Nawwwwwwww.......

I hope the Democrats are getting the message down DEEP and are scared to death of what is to come.

...Time to get out of Hell A, folks, and Californy. When it falls into the Pacific and is flushed away, the better this country will be. Ahhhh, Arizona Bay. Buy some desert now...

When is Congress going to pass legislation dealing with the serious problem of global pulling? The world demands action!

Article says highly pressurized water is the problem. But my guess it oil is the problem. We need to pump out the oil and burn it to increase the friction down there.

Dang that Bush for coopting the sun and moon to do his anti-California dirty work.

This reminds me there was this guy on Coast to Coast, who claimed the same thing about tides and earthquakes.....

Oh ridigulous, man and man only affects the climate, ask Al Gore (By the way, he also invented the internet...and fire too!)

Oh please Lord, not that!

It's bad enough just being L.A.

When Baja Californis gets dragged across the negotiated Border meridian, does it become US territory?

NOW, NOW.

THIS SCIENTIFIC FINDING SIMPLY CANNOT BE TRUE.

Strategerist has decreed that such is impossible, so it simply cannot be true.

By the time Frisco reaches Eureka it will be 8,652 feet under the Pacific Ocean causing the seas to rise 4,326 feet but by that time Eureka will be at 6,478 feet above sea level...

It will pass. After that ordeal, you will move on to Anchorage.

You mean there ARE really deep sources of water? Like what the Bible called in Genesis, the “fountains of the deep” that helped flood the earth in the time of Noah?

Naaaaaawwww!
