- Create a disaster plan
- Prepare a plan/list of things you would grab in case of an earthquake
Things you should discuss with your family are:
- Plan where to meet if you get separated.
-Make a supply kit that includes enough food and water for several days, a flashlight, a fire extinguisher and a whistle. Include non-perishable foods, cleaning supplies, and water for several days, in case services are cut off in your area.
