Well here in San Diego we just had an earthquake. Don't know where the epicenter was but it shook long enough for me to think that someplace just got walloped pretty good.

never mind. only a 5. Hit a bit south of Mexicali. But it felt to me like it lasted 20-30 seconds.

edited to add: oops 5.9 looks like it was right on the San Andreas. That can be damaging. been there done that. Comes with the territory.

If it weren't for the earthquakes, fires, and mudslides...glad you survived. Still waiting for the big one though, right?

There is a range of mountains between San Diego and the San Andreas. Distance is everything when it comes to earthquakes. If you are more than 50 miles from the epicenter, chances are you will not have major damage.

The wopper will be near Los Angeles. The San Andreas makes a couple of bends there along the back of the San Gabriel Mts. It's locked up and can't move easily. So when it does let go it'll be huge.

An interesting note for Rat 1. The main trace (surface markings) of the San Andreas fault passes directly under the interchange of Interstate 10 and interstate 15. When the big one comes, that area will be totally shut down. I took a Geology class at Pomona College. The class took a field trip out that way (~1974) and the professor pointed it out. Don't know what the area looks like now, but at that time there were enough open fields that you could see the depression heading straight for the intersection.
 
Gotta figure that you are about 200 miles away from the epicenter. You wouldn't feel a 5.8 that far away.
 
I live is AZ and didn't feel anything, but I'm still waiting for CA to slide into the ocean so we can have beach front property. :D

I lived through a lot of earthquakes when I lived in LA and Goleta. I always thought the "Slip Slidin' Away" would be a better theme song for the PRK.

Earthquakes can hit pretty much anywhere. I had one wake me up when I lived in NYC.
The epicenter was a few miles north of the city in the village where my parents lived.

I am glad so many of you did NOT notice this one! :D
 
Glad everyone is ok Frank. My main drill during the many earthquakes I have experienced, is to go into the garage, check the water heater is stable, and then smell for gas leaks, then go back to bed. The 10 and 15 fwy have lots of shops around. The Bass Pro Shop is just about a stones throw north of there. It takes about 4 hrs. to look around it is so huge. I hope the trout/bass/catfish show tank handle the earthquakes. That area is also on alluvial fan, so it will absorb the tremors well. Or at least that's what my dad the structural engineer tells me.:D

Your dad is incorrect according to the seismologists. You want to be on solid rock rather than on alluvium because the earthquake waves are smaller in solid rock.

Experience shows that the damage done by destructive earthquakes is much greater on alluvial soil than on solid. rock.

Yep solid subterranean support is the way to go. Solid rock would be best, and as the majority of particles gets smaller the worse the area takes damage. Soil can have liquefaction that can swallow entire city blocks.

I live in Irvine, didn't feel a thing, but others I know did.
