Even moderate shaking can do irreparable damage to things of value, to you to say nothing of the injuries that they can cause when they fall or shatter. Falling objects or breaking glass can also occur during everyday horseplay, in a windstorm, due to vandalism or when exuberant pets dash through your home. Keeping your hot water heater upright after an earthquake can also mean preserving a precious supply of potable water. Strapping kits can be purchased at hardware and building supply stores. Bolt down any gas appliances and make sure flexible connections are secure.
Fire is a serious secondary hazard following an earthquake.
Remove or seriously secure large, heavy objects that hang over sitting or sleeping areas. Heavy eye screws into studs are much more likely to hold hanging plants and heavy artwork. Brace and secure overhead light fixtures, items that commonly fall. Secure heavy objects that may topple over into wall studs with L brackets and 3 inch lag screws. This is particularly important with heavy, unstable items like bookcases, grandfather clocks, entertainment centers.
