Tsunamis in Canada

In a total of 11 tidal waves classified as a tsunami since 1903 a total of 45 people died in Canada. Compared to other countries, Tsunamis therefore occur rather rarely.

The strongest tidal wave registered in Canada so far reached a height of 38 meters. At this Tsunami on 12/04/2007 no losses of human lifes have been registered.

The biggest impact in terms of lifes, injuries, destroyed homes and economy had been a tsunami on 03/28/1964.

The marked positions on the map represent the most effected regions within the past 120 years.

Tsunamis are caused by earthquakes or other seismic eruptions on ground of an oceans and can cause massive tidal waves, which run with enormous force on land, causing great devastation. Especially in regions with only few tsunamis, the damage is often drastic, as the population does not expect tsunamis and thus hardly takes any protective measures. Even relatively small flood waves can lead to high losses and financial damage.
