Not only is there no chance of evacuating from the Bay Area due to the size of the population, there aren’t too many places to go to that could support the mass of unprepared people. I’m a long time resident, and the only sane plan is to shelter at home. My only “bug-out” type of preparation will be to insure that if I am stuck at work when the “Big One” hits, that I will have sufficient supplies to make it home somehow. I will probably keep a mountain bike locked up in the back of my truck. I always have basic supplies with me. I stay in good enough shape where I could walk home (25 miles) if I absolutely had to do so. Earthquakes are the only real threat where I live. Wind would carry any bad stuff to the East of where I live should there be a terrorist event. All of the refineries are East of my house. I am high enough where a Tsunami is extremely unlikely. Other than an Asteroid strike, Earthquakes are the only threat.
