Experts: L.A. Quake Fault "Capable of Massive Temblor"
KTLA News ^ | March 18, 2010

The moderate earthquake that struck the Los Angeles area Tuesday likely occurred a long a fault that could generate a much stronger, major quake in the future, according to scientists.

Seismologists say the Puente Hills thrust system could touch off earthquakes up to magnitude 7.5 directly underneath downtown Los Angeles. Such temblors would prove larger than any in the modern history of the Los Angeles Basin.

The Puente Hills fault, which winds through the area's fractured underbelly for about 25 miles -- from northern Orange County to Beverly Hills -- has generated at least four earthquakes ranging from magnitude 7.2 to 7.5 in the last 11,000 years, according to a study published in the journal Science.

"The bad news," the report said, "is that when the Puente Hills thrust fault ruptures in an earthquake, it tends to do so in a very big way."

Tuesday's magnitude-4.4 quake struck at 4:04 a.m. and was centered 1 mile east-northeast of Pico Rivera, according to the U.S. Geological Survey.

There were no reports of serious damage or injuries.

Residents as far away as San Diego and Santa Clarita reported feeling the quake, which consisted of some rumbling and a quick jolt.

Seismologists have not determined which fault was responsible for Tuesday's shaker, however, Daniel Ponti of the U.S. Geological Survey told the Whittier Daily News that it was likely on the Puente Hills thrust system.

A thrust fault is just one of the ways the earth slips. There are faults all along the coasts where the plates meet. All different kinds. All of them are Bush’s fault, of course.

No kidding. What’s the “experts” next feat of cranial wonderment? Predictions of snowfall at the North Pole?

Seattle is due for their 300 year ~9.0 magnitude quake since the last one was in 1700CE.

Who will get hit first? L.A. or Seattle?

Chile lies alongside a subduction zone where oceanic material is subsumed back into the mantle. Foci are relatively deep, 35 to 200km or more.

LA from roughly San Diego north to Crescent City is “transpressive” with strike-slip and thrust faults, mainly shallow focus to about from 5 to 15km or so. I’d rather live here than there.

CE is Christian Era or Common Era.
BCE is Before the Common/Christian Era.

Jews use it and no one else that I know of.

The quantified predictions are the equivalent of Global warming conjecture. There is no way the man knows what he said.

Libs use CE and BCE, it's the politically correct dating system, I know what it stands for.

I have never seen Jews use anything but Before Christ or Anno Domino, BC and AD.

They are still searching for one named Bush's fault.

And Jews are the ones who have a disproportionate amount of influence on other cultures because of the trends they start.

Why do you think Jews would use BCE and CE instead of AD and BC? Think about it for a sec.

Being an incurable nerd, I got an app for my i phone called Quake Watch. The daily number of very small quakes in California are amazing. Responsible are a profusion of volcanic areas and fault zones which don’t necessarily affect each other.

Yes, you are correct.

It does kind of bother me that while 4.4 is NOT a big quake, usually even those have aftershocks. So far this one hasn't.

It's making me a little nervous.

It was a little deep for this area at 18.9km (11.7 miles). ‘Could be that relatively small motion is tectonically locked in down there, thus no after shocks. It could also be that this event was an aftershock of several others over the past 10 years or so. Though undoubtedly it’s a sign of accumulationg stress along at least that part of the overall SoCal system, which will eventually bust out somewhere therein sooner or later.

Here's a fairly recent abstract from "Geology". The article's for sale but the details seem pretty straight forward otherwise.
