Natural disaster rankings.

From worst to "best":

1. Earthquakes: Not predictable, widespread disaster area, no reasonable shelter available
2. Hurricanes: Widespread disaster area, no reasonable shelter available (other than evacuation), but short-term predictable
3. Volcanoes: Somewhat limited disaster area, no reasonable shelter available (other than evacuation), sometimes short-term predictable
4. Blizzards: Widespread disaster area (but relatively limited property damage), reasonable shelter available, short-term predictable
5. Serious flooding: Somewhat limited disaster area, no reasonable shelter available (other than evacuation), short-term predictable
6. Tornadoes: Limited disaster area, reasonable shelter (unless you're in a mobile home), very-short-term predictable
