You seem to live peacefully on the San Andreas Fault. Or maybe a couple blocks away from it.
I wondered if you've made any preparations for TBO. (The Big One)
I've done a few things for my daughter in Redondo Beach. I got her a couple cases of MRE's to stick in a closet. Since lack of water is the most severe problem, and she has two housemates, I got her three 55-gallon drums and some chlorine-smelling additive. We put the drums in different spots in case all/part of the house collapses, one or two of the drums might survive.
I tell her to keep her tank half full, and keep plenty of pet food.
I managed to get the two pistols to her, with a bunch of ammo and a safe to keep them in... Her house mates are anti gun, and don't know about them. Maybe someday she'll use them to save the sorry asses of the housemates.
Any other thing you would do in case all services are cut off for weeks, and the social fabric breaks down for a while?
