What is a tsunami?
A tsunami, usually triggered by a major earthquake occurring beneath the ocean floor, consists of a series of large waves that can reach several metres in height. These waves will strike coastal areas and can happen with little warning.
What to do before a tsunami
- Stay informed by listening for advisories on TV, radio, or social media (e.g. Emergency Info BC on Twitter:
@EmergencyInfoBC ). Depending on the threat level, you may need to evacuate to higher ground.
Tsunami Alert Levels
|
Alert level |
Potential Hazards | Action |

| Advisory | Strong currents likely | Avoid shoreline |
| Watch | Danger level unknown | Stay alert for more info |
| Information Statement | Minor waves expected | No action required |
| Cancellation | No wave activity | Confirm safety of local areas |
- Check your home for potential flood risks and, if possible, repair any vulnerabilities.
- Create a
home emergency kit and/or a “go bag” in case you need to evacuate quickly. Your kit should contain:- Water
- Ready-to-eat, non-perishable foods (don’t forget to pack food for your pets)
- Battery-powered or wind-up radio
- Battery-powered or wind-up flashlight
- Extra batteries
- First aid kit
- Prescription medications
- Important documents (identification, passports, etc.)
- Cash
- Know how to turn off the gas and electricity in your house.
- Have an evacuation plan as well as a way to get in touch with family members if you’re not all in the same area. Don’t forget to include your pets!
During a tsunami
- Get to higher ground and stay away from shorelines.
- If you’re not able to evacuate, stay inside and away from the windows. Try to keep to the side of the house that faces land.
After the tsunami
- Stay indoors until authorities tell you the area is safe.
- If you had to evacuate, don’t return home until you’ve been told by authorities that it’s safe to do so.
- If you’re able to leave your home, avoid any flooded areas and washed out bridges.
- Restock any supplies from your emergency kit.
Unfortunately, flooding caused by a tsunami isn’t covered under a standard home insurance policy or by overland water coverage. If you have damage caused by flooding, you may be able to qualify for government assistance.
