Make sure your TV is anchored to the wall, as well as anchoring the furniture it is sitting on. Also anchor bookshelves, and anything that could tip over. Any baby proofing straps will work, although it is recommended to not use the all plastic straps.
Anchor all cupboard doors – especially if they are higher up, like kitchen cupboards. Make sure doors with dishes and glass behind them are anchored shut. I personally use earthquake latches, as they won’t unsnap during shaking like other baby proofing spring or magnetic clasps. The cheaper knock off brand can be found here.
Museum Wax, Museum Putty, or Quake Hold are all products similar to blue-tac that help secure items on display to shelves in the home.
Secure pictures and mirrors using either a French cleat or Z-hanger style for heavy pieces, or a wire backing with hook style found in most picture hanging kits.
Make sure other heavy household items are anchored, including your water heater.
Check your home or renter insurance to see if earthquake damage is covered or can be added. More info can be found on the insurance page, however this Q&A by the Seattle Times is specific to earthquake insurance in Washington.
Again, most non-life-threatening injuries from an earthquake are from broken glass. Please prepare accordingly. If in bed, the safest place is to stay in bed – and this is one reason why. Keep under the bed gear to protect your feet, hands, and head. Also, make sure to have a good first aid kit on hand.
