Preparing for an earthquake
What matters most in an earthquake, what official guidance in the US says, and long-life food that suits it.
In an earthquake, the things that matter most are first aid kit, flashlight, meeting point, utility shut-offs. In an earthquake, drop to your hands and knees, cover your head and neck, and hold on until shaking stops.1
What matters most
- First aid kit Essential
A stocked first aid kit that everyone knows where to find. - Flashlight Essential
A flashlight for each part of the home you'd need to move around in the dark. - Meeting point
Somewhere your household agrees to meet if you're separated. - Utility shut-offs
Where to turn off water, gas and electricity. - Drinking water Essential
3 litres per person per day for drinking is the commonly recommended amount. - Food for everyone Essential
Non-perishable food that will last your household for your chosen number of days. - Emergency contacts Essential
Important numbers saved where you can reach them without the internet. - Important documents

What official guidance in the US says
- In an earthquake, drop to your hands and knees, cover your head and neck, and hold on until shaking stops.1
- If you're indoors, stay inside; don't run outside or stand in a doorway.1
- If you're in bed, turn face down and protect your head and neck with a pillow.1
- If you're driving, pull over, stop and set the parking brake.1
- Secure heavy items like bookcases, fridges, water heaters and TVs before an earthquake.1
- Expect aftershocks after the main earthquake.1

Allergies, dietary needs and children
Plan around everyone at home: allergies, intolerances and diets come first, and familiar food matters most for children. Recipes vary between brands, so always read the label of the product you buy.
| Food | Typical allergens | Typically suitable for |
|---|---|---|
| Canned chili | varies by recipe | check the label |
| Canned soup | varies by recipe | vegetarian |
| Baked beans | none of the main allergens in its main ingredient | vegan |
| Microwave rice pouch 250g | none of the main allergens in its main ingredient | vegan |
| Canned tuna | fish | check the label |
| Crackers | cereals containing gluten | vegan |
| Peanut butter | peanuts | vegan, gluten free |
| Dried fruit and nuts | tree nuts | vegan, gluten free |
| Granola bars | varies by recipe | vegetarian |
| Canned fruit | none of the main allergens in its main ingredient | vegan, gluten free |
Typical allergens and diets are SupKit's guide to the main ingredient, not a product's label.
- US law names nine major food allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and sesame (sesame added from 2023).2
- Labels must name each major allergen's source, either in brackets in the ingredient list or in a 'Contains' statement next to it.2
- 'May contain' warnings are voluntary in the US, so not every maker uses them and their absence is not a guarantee.3
