Only if some action happens after reading - assemble an earthquake kit, get CPR certified, join your local CERT. I think one of the things that did happen after this (starting after the LA fires in the 90’s) was the idea of training Community Emergency Response Teams. I volunteer at my local one and we do quarterly classes as well as a drill. It’s well worth checking out.

My own 89 earthquake story is not so traumatic - I walked from downtown to ocean beach along Geary, and all the Irish bars were giving away free beer. Could see the smoke from the Marina but had no idea of the terrible things happening over there.
