I have an earthquake kit - candles, matches, flashlight & batteries, wrench to shut off gas if needed, food for self and cats, basic first aid stuff, blankets, water, spare contact lenses, other stuff. I have a garden that supplies food (whether or not there is running water makes a big difference). Can turn barbecue into stove if need be. Obviously there are degrees of disaster. A 10 hour shutdown is bad but my house flattened and the neighborhood on fire from ruptured gas lines is much worse. There are some things you just can't plan for. I'm out of tsunami range, but how do you plan for that? Sometimes you just have to get out.
