In my circumstances, I need to be either to flee (wildfires) or bug in (earthquakes). In terms of preparation, it sees to come down to the same thing - preparedness is preparedness
On the edge of town, my home has been threatened twice in the last fifteen years by spreading wildfires less than 1/4 mile distant. Both times I have loaded up the car following our written check list and have been ready to turn the key and drive away. Interestingly, none of my neighbors appear to have made any preparations on these occasions. Possibly none of them have experience fighting wildfires - I do.
Earthquakes provide no advance warning and I may not even have a realistic option to flee. My inclination, in any case, is to hunker down and deal with the consequences of the tremor, including fire. I would basically camp out in the yard for the duration.
In preparing and storing supplies, I realize that storage within the house might render supplies inaccessible or damaged due to the shaking. I resort to a dispersed strategy, with goodies stashed where I think I can reach them, even after the quake.
Two of these relatively safe locations are our vehicles (they are routinely parked in the open). They thus carry at least minimal gear, and I try to refuel them when the tanks are about half full. In a bug in scenario, I would use the alternators to provide 12VDC, and use a converter to power various small electrical appliances. In preparing to hunker down, I have also prepared to flee...
I make sure I have a pair of sneakers, spare glasses, gas shutoff tool, and a stout pry bar right at hand next to the bed. The water heater is bolted down. Ah, life in La-la land!
