I wouldn't worry about the quakes. We only saw Hale-Bopp 2 years before it passed - too late to do anything about it. Eventually, we'll miss a big-rock and since everyone is walking around with their heads planted firmly up their backside whining about taxes we will never be prepared. How may planets have produced sentient life that lacked the intelligence to survive? I know of one.
some scientist on the radio today was predicting 2030 for the bay area. but he also thinks earthquakes are correlated to lunar cycles (like, the big ones happen more often during full moons).
another subtopic the recent Chilean earthquake was a megathrust earthquake and the upcoming Big One is supposed to be:
http://en.wikipedia.org/wiki/Megathrust_earthquake
Megathrust earthquakes occur at subduction zones at destructive plate boundaries (convergent boundaries), where one tectonic plate is forced (or subducts) under another. Due to the shallow dip of the plate boundary, which causes large sections to get stuck, these earthquakes are among the world's largest, with moment magnitudes (Mw) that can exceed 9.0. Since 1900, all five earthquakes of magnitude 9.0 or greater have been megathrust earthquakes; in fact, no other type of known tectonic activity can produce earthquakes of this scale.

When Will The Big One Hit Los Angeles!?
Are you talking about the once in 10 years type? Then within the next ten years.
Are you talking about the once a century type? The probably before 2100.
The real question is what magnitude is Los Angeles prepared for and how much damage would a bigger one do.
Nearly every disaster I have heard about was an event which has happened before on record in the same area and the main reason it became a disaster is lack of preparation from the locals who should have known better. Of course it is always a matter of balancing cost vs risk, but in many cases the risk was known to be high and the cost would have been worth it (New Orleans for example).

i've heard a red cross rep. say not to hide in doorways. that myth started when an early earthquake expert traveled to chile and saw all the unreinforced adobe buildings tumbled down except for the doorways. he came back to the US and recommended that and it spread. california building codes are different and esp. modern codes are much better, so you shouldn't have much to worry about, unless the shelf drops off into the sea. i am a few miles east of the san andreas; i'll save you a tin of biscuits.
