How to Make an Earthquake Home Kit

Gather the items recommended by FEMA.
Make two lists of each item to be stored in the kit, one to keep inside it and another somewhere everyone can get to, like under a magnet on the refrigerator door.
Store in tightly sealed plastic bottles one gallon of water per person per day for three days for families that are evacuated or for two weeks for the homebound.
Get enough non-perishable, easy-to-prepare food items to last three days for the evacuated or two weeks for the homebound.
Collect enough medications to last seven days.
Keep enough cash in the kit to last the family three days or two weeks depending on where you'll end up.
Fill out the card for the emergency contact who is out of state because, after a disaster, and if phones are even working, it's usually easier to place long distance calls than local ones.
Include the contact and each immediate family member's work, school and mobile numbers on the Emergency Contact Card the Red Cross recommends everyone carry at all times. You can print one free at http://www.redcross.org/prepare/ECCard.pdf.

Take stock of how much room your assembled items require.
For smaller kits, fit everything in one, easily accessible container.
If all items under "Things You'll Need" are included, the container may have to be the entire garage. (Plan accordingly.)
Store everything in waterproof containers that are easily portable, such as duffel bags or garbage cans on wheels.
Depending on how many items each person or pet requires, consider segregating items by person or animal in the single kit. Or, keep separate kits so needed items (especially medications) are more easily found, especially in the confusion of disasters.
Place the finished kit or kits somewhere easy to access, avoiding anyplace under heavy beams or near windows, electric outlets or flammable materials.

Keep kits fresh, whether for pets or humans.
Run a disaster test to make sure the kit "works." Have one person consult the checklist on the refrigerator, another the copy in the kit and check off each item to ensure they are still in place.
Replace anything missing.
Examine each item closely. Replace any item no longer up to snuff.
Check expiration dates, even on non-perishable food.
Change out the water at least once a year.
Pack and repack the kit every six months.
Do not store it and forget it.
