There are multiple ways you can prepare for natural disasters. For example, the Volunteer Mobilization Center Floor Plan to the left was developed after the lessons of many hurricanes in Florida.
It is an efficient way to vet people with skills (tree trimmers, nurses, first responders) from the curios and criminal. It is a good way to get personnel with necessary skills out to the disaster site and preventing those who are not skilled or who have criminal intent.
The greatest lesson of preparing for any natural disaster is to do the work BEFORE they arrive. For example, store enough water to make it through two weeks (Waterbricks).
Here are some resources to help you do so.
