The LA area is so spread out—issues would probably be localized.
SF is the worst place to be in “the big one” imho—especially since things have gone downhill there since the last big quakes.
A 7.8 would destroy much of the infrastructure in S. CA. then the fires would take out much of the rest. Serious damaging aftershocks would go on for many months possibly triggering other faults..
Wait until the pools dry up.
