Preparing for a disaster means having enough emergency food, water and other emergency supplies to last at least 14 days – longer, if you live away from an urban area that is likely to receive outside aid early in the recovery period.  In addition to a “go bag” or “bug out bag” that you keep in your car or hall closet, you should make sure to have other resources stored up that are easily reachable even if your home is damaged.

This list of Emergency Supplies for Earthquake Preparedness prepared by the Centers for Disease Control is one of the most complete we’ve seen for first aid kits, as well as detailing survival kit suggestions for home, auto and workplace.
