When I put my earthquake kit together in 2007, it was because Michael and I were superstitious. I don't think I have to explain why we felt it was necessary to revisit our supplies this weekend.
This is what we've added:
A First Aid kit. (A big omission the first time around.)
A crow bar.
Waterproof matches. (We live in Victoria, after all.)
Freeze-dried meals, including space ice cream to lift our spirits. (The meals don't expire until 2016, so they're worth the investment.)
Water purification tablets.
We also added more bottled water, a survival handbook and a windup radio/flashlight since that original photo was taken.
If you live in an earthquake zone, I hope you're taking appropriate measures too; hopefully we'll never have to realize the fruits of our labour.
