Answer:
Before:
Find out if your home, school, workplace or other frequently visited locations are in tsunami hazard areas. For high risk areas, know the earthquake and tsunami plans for each location.
Contact your municipality to know the risks, evacuation and alerting system in your community. Know the sound of the alert and make sure all in your family are familiar with it and what to do. Sign up for local alerts.
For up-to-date information from coast to coast to coast, the Government of Canada and the Canadian National Seismograph Network monitor significant earthquake reports in Canada.
after:Be prepared for aftershocks, which could generate another tsunami.
Return home only after local officials tell you it is safe. A tsunami is a series of waves that may continue for hours. Do not assume that after one wave the danger is over. The next wave may be larger than the first one.
Be aware of secondary effects. These include landslides, contaminated water, mudflows, damaged bridges, buildings and roads, and other hazards.
Only make calls if you require emergency services.
Stay out of any building that has water around it. Tsunami force can cause floors to crack or walls to collapse.
If you suspect your home is unsafe, do not enter. Rely on the professionals to clear your home for re-entry, if you are unsure.
Do not light matches or turn on lights or appliances until you are sure there are no gas leaks or flammable liquids spilled. Avoid use of contaminated water.
Place a HELP sign in your window if you need assistance.
hope it helps.
