Tsunamis in Vanuatu
A total of 13 tidal waves classified as a tsunami since 1875 have killed 5 people in Vanuatu. Compared to other countries, Tsunamis therefore occur rather rarely.The strongest tidal wave registered in Vanuatu so far reached a height of twelve meters. On 01/10/1878, no losses of human lifes have been registered by this tsunami.
The biggest impact in terms of lifes, injuries, destroyed homes and the economy had been a tsunami on 11/26/1999. A tidal wave of up to 6.6 meters killed 5 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.
