What is a Tsunami

A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions above or below water all have the potential to generate a tsunami.

Deaths caused by Tsunamis

Between 1998-2017, tsunamis caused more than 250 000 deaths globally, including more than 227 000 deaths due to the Indian Ocean tsunami in 2004. Tsunamis can travel thousands of kilometres with speeds up to 800 kilometres per hour. Once they reach the coast, they can have devastating impacts on the community.

Name origin

The word tsunami (pronounced tsoo-nah'-mee) is composed of the Japanese words "tsu" (which means harbor) and "nami" (which means "wave"). ... Thus, the Japanese word "tsunami", meaning "harbor wave" is the correct, official and all-inclusive term.
