I live in Los Angeles and have concluded that evacuation will be near impossible after a quake since our freeways are gridlocked during a normal day. Collapsed overpasses will impede almost all freeways leaving only limited surface roads. And how could the surrounding areas absorb up to several million people?

Several years ago I purchased a large tent, about 10' x 15' on sale at Costco. Not a perfect solution, but it gives me the option of setting up a tent in my large back yard if my house collapses. You might consider buying a large tent from a hunting supplies catalogue. Not a perfect solution but an option.
