Background about Tsunami

The word “Tsunami” comes from the Japanese language, where “tsu” means harbour and “nami” means wave. Thus, the literal meaning of tsunami is “harbour wave.” Although tsunamis are often incorrectly called tidal waves, they are not caused by tides. Instead, they are usually generated by underwater earthquakes, volcanic eruptions, landslides, or meteorite impacts beneath the ocean.
