Sobriant74 has a list of some basic things to prepare for emergencies.
Here's a condensed list:
1. Water (and a plan how to get more)
2. A gun.
4. Gardening equipment and seeds.
5. Write it down and share so if you kick it, your friends and family can get to it.
6. Have a productive hobby
7. Don't panic.
Standard stuff. I'll add that you make sure you know how to do all of these things. Having a gun isn't going to be nearly as useful if you don't know how to shoot it, same thing for gardening or feeding yourself. You should know the basics of cooking.
By productive hobby Sobriant74 cites things like making shoes, or matches. Things that are useful skills if things really go to hell.
Myself, I do French and Indian war era reenacting and primative camping.
All this stocking, preparing, and training also has the upside of helping #7. Being prepared helps stave of panic.
But don't worry, disasters never happen.
And even if they do the media will do its duty and tell us all about it.
