Tsunamis in New Caledonia
In a total of 10 tidal waves classified as a tsunami since 1875 a total of 25 people died in New Caledonia. Compared to other countries, Tsunamis therefore occur rather rarely.The strongest tidal wave registered in New Caledonia so far reached a height of 3 meters. At this Tsunami on 05/01/1942 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 03/28/1875. A tidal wave of up to 2.5 meters killed 25 humans and destroyed vast areas.

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.
The marked positions on the map represent the most effected regions within the past 150 years.
