If living near an earthquake zone, houses should be assessed for earthquake resistance and suitable precautions made to minimize structural damage in the event of such a disaster. If close to the house, trees that are large, old, or leaning should be removed. Soil condition can be checked by the local building authority or soil engineers. Loose, silty sand and clay soils do not provide a solid foundation during an earthquake, resulting in a quick-sand effect. If soil is found to be poor, foundations should be extended deep into the ground.
Corners are especially vulnerable and can be strengthened using steel rods.
Chimneys should also be reinforced. Check that light fixtures, paintings, fans, mirrors, and any other wall or ceiling hangings are securely fastened. Bolt cabinets and bookshelves to the wall. Consider replacing windows with safety glass. Ask your insurance company about earthquake insurance.
