There is a section here on ETS that will give you a great start - adapt it to your circumstances. Out here in California, someone always sells "earthquake kits" after a major shaker. Uniformly they are pretty junky and way overpriced, although probably better than nothing at all.

You named the basics in your post. Just off hand, be sure you have good flashlights and adequate batteries to power them and your radio, lots of plastic bags for wate disposal, etc. (very versatile), a good basic first aid kit, and good reading material, crossword puzzles, etc. to pass the time.

Just now saw a news release on CNN advising us all to stock up for threat level "Orange". I am off to supplement my supply of plastic sheeting. Don't forget the duct tape. <img src="images/graemlins/cool.gif" alt="" />
