Prepare for tsunamis
Tsunamis are a series of large waves. They happen when earthquakes, landslides, volcanic activity, or asteroid impacts displace large volumes of water. More than 85% of known tsunamis were generated by an earthquake or a landslide generated by an earthquake. Each tsunami wave may last from five minutes to more than an hour. As tsunamis move into shallow coastal waters, they grow in height.
Why prepare for tsunamis
Although tsunamis in Canada are rare, they do occur and can cause major damage and loss of life. They can happen on any Canadian coastline including the Atlantic and Arctic Ocean Coasts, and interior waterways. Low lying coastal areas are typically most at risk during a tsunami event. Coastal British Columbia has the highest tsunami risk in Canada.
