I don't understand why this guy cares so much. honestly, he is not a scientist or geologist, so really he knows nothing, I heard and read stuff that actual scientists documented saying it would be severe ALL over Southern California including San diego.

I've heard that too having been in SD for so long but sometimes we gotta pick our battles.

Growing up in the Bay Area, I can tell you...um...no! 5's are when quakes stop feeling fun.

Yeah. The San Andreas Fault cuts through that pass. The San Gabriels have been carried northwestward on the left side of the fault; (left side if you're looking northwest at that point).

And growing up in Los Angeles I can tell you it depends on the details. A 5.0 with high ground acceleration is going to produce more damage than a 5.0 with weak ground acceleration. It also depends on what sort of soil you are under. I've experience both, the most extreme ground acceleration I've felt was in the Northridge quake (I was in the valley at the time). In the 1994 quake I tried to get up, but was pushed to the ground by the violent shaking. In other quakes I was able to move much easier.

You mean like the people at Forest Lawn?

No, the exact opposite. Google on "Ft. Tejon Earthquake 1857"

That locked section from Joshua Tree to Parkfield will be a massive quake if the entire portion ruptures. Of course, it is possible that only part of the locked section may rupture. Worst case though would be a redo of 1857. If that happens ... I don't want to think about it. It would be bad for both SoCal and the Bay Area not to mention many places in the San Joaquin Valley and Central Coast.

I wish you were right. See the August report from the journal Geology covered in this article today: Earthquake experts see the "Big One" getting bigger - latimes.com

Yeah I read this as well along with the bigotted comments section

I don't care what anyone says if an 8 pointer or above hit the San Andreas the damage would be extensive from San luis Obispo to San Diego to baja over to Western Arizona. I say San Diego because an earthquake that large roaring down the San Andreas for 340 miles will be felt here strongly no matter what anyone says. All of Southern California, Northern Baja, Western Arizona will be heavily affected by such an event.

The article in today's LA Times is sobering and consistent with other announcements by seismologists of an imminent major earthquake. Not that we can do anything about it other than making sure we are prepared for such an emergency.
