An earthquake is the result of the sudden movement of two blocks of bedrock along a break, or "fault", deep in the earth's crust.

Preparing your home for an earthquake

• Move or secure objects that could fall and injure you
• Secure objects that could start a fire or break gas or water lines if they topple, such as the water heater and other heavy appliances (e.g. stove, washer, dryer)
• Locate beds and chairs away from chimneys and windows
• Use child-proof or safety latches on cupboards to stop the contents from spilling out
• Keep flammable items or household chemicals away from heat and where they are less likely to spill

During an earthquake

• Expect the ground or floor to move, perhaps violently. You will probably feel dizzy and be unable to walk during the earthquake. If you live in a high rise or a multi-storey building, you may experience more sway and less shaking 
• A moderate earthquake might last only a few seconds while a large earthquake could last for several minutes
• Wherever you are when an earthquake starts, take cover under a strong structure away from windows, shelves, and heavy hanging objects. Cover your head and neck and stay there until the shaking stops
• If you are in a vehicle avoid bridges, overpasses, buildings, power lines, or anything that could collapse on you and your car
• After shocks can occur when the earth underneath the surface adjusts to it's new position, stay in a safe area until the aftershocks have stopped
