Tsunamis in French Polynesia

In a total of 13 tidal waves classified as a tsunami since 1837 a total of 2 people died in French Polynesia. Compared to other countries, Tsunamis therefore occur rather rarely.

The strongest tidal wave registered in French Polynesia so far reached a height of 20 meters. At this Tsunami on 04/01/1946 a total of 2 people have been killed.

The marked positions on the map represent the most effected regions within the past 190 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.
