Be prepared for aftershocks

Stay calm. Help others if you are able.

Be prepared for aftershocks.

Listen to the radio or television for information from authorities. Follow their instructions.

Place corded telephone receivers back in their cradles; only make calls if requiring emergency services. Put on sturdy shoes and protective clothing to help prevent injury from debris, especially broken glass. Check your home for structural damage and other hazards. If you suspect your home is unsafe, do not re-enter. Unplug appliances and broken lights to prevent fire starts when the power is restored.

Stay away from brick walls and chimneys as they may be damaged or weakened and could collapse during aftershocks. Do not use your fireplace if your chimney has been damaged as a fire may start or gases could be released.

If you have to leave your home, take your emergency kit and other essential items with you. Post a message in clear view, indicating where you can be found. Do not waste food or water as supplies may be interrupted.

Do not light matches or turn on light switches until you are sure there are no gas leaks or flammable liquids spilled. Use a flashlight to check utilities and do not shut them off unless damaged. Leaking gas will smell like rotten eggs.

If your home is equipped with natural gas: Call your gas provider immediately to report any concerns or if you smell gas (rotten egg smell). Shut off gas valve if you know how. Once the gas is turned off, don't turn it back on. Only a licensed gas technician can turn the gas on safely.

If tap water is still available immediately after the earthquake, fill a bathtub and other containers in case the supply gets cut off. If there is no running water, there may be water in the hot water tank (make sure water is not hot before touching it) and toilet reservoir (not the bowl).

Do not flush toilets if you suspect sewer lines are broken.

Use extreme caution with hazardous materials or spills. When in doubt, leave your home. Check on your neighbours after looking after members of your own household. Organize rescue measures if people are trapped or call for emergency assistance if you cannot safely help them.

If you have pets, try to find and comfort them. If you have to evacuate, take them to a pre-identified pet-friendly shelter. Place a HELP sign in your window if you need assistance.
