Tsunamis in the Capital RegionA tsunami is a natural hazard, consisting of a series of long, surge-like waves that are usually caused by an underwater earthquake, landslide, or volcanic eruption.
The main tsunami threat to the Capital Region is from a Cascadia Subduction Zone (CSZ) earthquake off the Pacific Coast of Vancouver Island, which could result in a local tsunami.
An earthquake may happen far away that we won’t feel, causing a distant tsunami. This is a very low-risk and low-impact event for the Capital Region.
Sometimes, distant tsunamis are preceded by water rapidly moving away from the shore. If this happens, move to higher ground.
Projected Local Tsunami Arrival Times
LocationMax Water Level (m)/(ft)*
Tsunami Arrive Time (min)
Port Renfrew 3.5 / 11.5 35
Sooke Harbour 2.5 / 8.2 60
Esquimalt Harbour 2.7 / 8.9 76
Victoria Harbour 2.5 / 8.2 76
Cadboro Bay 2.0 / 6.6 90
Sidney 2.0 / 6.6 110
* These estimated levels are based on a 9.0 CSZ earthquake.By contrast the 2011 Japanese tsunami caused by a 9.0earthquake, had a maximum water level of 40 metres.

Be Prepared to Respond to a Tsunami Warning
Know your zone! Check the Tsunami Hazard Map on the reverse to see if you live, work, play, or go to school in a tsunami hazard zone.
If you do, here’s what you should do during a tsunami warning:
• Move to higher ground. If you are at four metres or 13 feetabove sea level, you’re safe from a tsunami in the Capital Region. You can look at the compass on your mobile device or Google Earth to find out your elevation.
• Move to higher ground on foot or bike if possible, to keeproads clear for emergency responders.
• Move away from beaches, marinas and bodies of waterand DO NOT go back to tsunami hazard zones until localgovernment officials tell you it is safe to return.
• DO NOT call 911 unless you have a life threateningemergency and stay off phone lines as they will be in useby emergency personnel.
• Stay tuned to local media channels for further instructions(Have a battery or crank-operated radio in your Grab-and-Gobag and know your local radio, TV, and trusted social mediasources of information).
Tsunami Preparedness Tips
• Know where higher ground is and how to get there(see map on reverse).
• Practise your evacuation routes on foot or bike with yourfamily members, friends or colleagues.
• Have Grab-and-Go bags ready for your family and petsto take with them. (See PrepareYourself.ca for tips onwhat to include.)
• Have a family reunification plan which includes evacuationroutes, emergency contacts, designated meeting places,and arrangements to stay with family or friends who are notlocated in a tsunami hazard zone.
• If you are not located in a tsunami hazard zone, be preparedto assist family and friends in need of shelter.
Tsunami Safety in the Capital Region
If you are near the ocean and feel an earthquake that makes it difficult to stand, move to higher ground or inland immediately. Do not wait for an official warning!
In the event of a tsunami warning, local governments will communicate instructions using various methods. These may include telephone/email/text alert systems, sirens, social media channels, websites, media outlets, or door-to-door visits.
Go to PrepareYourself.ca to find out which systems your local government uses, and if there is an alert system you can subscribe to.
