I'm sure that there are other good lists and considerations that aren't mentioned here; this above one is a bare bones list. A while back I picked up the Handbook to Practical Disaster Preparedness which I have been leafing through for ideas. Even if you don't get many of the things on the list, at least it will get you thinking about what you may need and what helps in certain situations.

Another disaster that seems to be well on its way is the economic one. When this economy finally does 'collapse' food may be difficult to come by for a while. The
Preparedness thread seems like a good place to start.
