Being prepared for an emergency can save your life, so being prepared for a flood, hurricane, or volcanic eruption can also help you prepare for a zombie apocalypse!
Water bottles-You can't survive without water for a few days so it's always important to have it during a disaster
Food rations-Similar to water even though you can survive without food for a month, you still need it to survive
Firestarter-It may get cold in the night if your power goes out so a firestarter will be useful, it will also keep bugs away
Blankets- Blankets could be used as an extra layer of clothing during the night
(hand crank) Radio/weather radar- To know what weather is coming and potentially know a rendevous point
Flashlight- To help see during the night
Whistle- To call for help if you see people
First aid- If you injured during the disaster
Using these things you can be prepared for almost emergency, maybe even a zombie apocalypse!
