What disasters are likely where you live?
Give it a rating of (very unlikely), (unlikely), (somewhat likely), (likely), (very likely).
Give it a likely time scale to happen: 1, 5, 10, 25, 50 years.
Give it a area of effect rating: family, neighborhood/business, city, state, nation, or planet.
These rating together will show you where you want to concentrate your resources at first.

Thinking about the effects of each kind of disaster will help you get ready for them. Thinking through what would happen and what you would need is a big step in getting ready.
