Well, neither of the faults they’ve been talking about are close enough to the ocean to be a factor.
The fault from Mexico which runs through the southern part of CA, could be the one that might trigger a major movement of earth. The last one we had from that fault was a 7.1 (several years ago), and it scared me so bad, I ran out of my apt and into the parking lot where there were no trees to fall on me. However, I neglected to take my car keys .. so if my apt had slid down the hill, I would not have been able to use my car. I have now changed that possibility.
Just felt one here in SoCal. Lasted about two seconds.
