a surge of water with a long wavelength produced by the displacement of a body of water. Causes of tsunami include an earthquake causing offset (uplift or subsidence) of the sea bed, a volcanic eruption, or a large landslide (including sector collapse). The height of a tsunami is influenced by the morphology of the coastline that it travels towards [..]

A tsunami is a giant sea wave produced by submarine earth movement or volcanic eruption. A tsunami is also referred to as a tidal wave.

(n) a cataclysm resulting from a destructive sea wave caused by an earthquake or volcanic eruption

A tsunami is a series of ocean waves generated by sudden displacements in the sea floor, landslides, or volcanic activity. In the deep ocean, the tsunami wave may only be a few inches high at the sea surface. When a tsunami wave comes ashore it will increase in height and can become a fast moving wall of water several meters high.

a giant and deadly wave Tube

A series of ocean waves characterized by having long periods and wavelengths that can travel with speeds greater than 500 miles per hour. Tsunami waves can be generated by sudden displacements in the sea floor, landslides, or volcanic activity. In the deep ocean their height may only be a few inches, but as they encounter shallow water their height [..]

Long period ocean waves generated by geological and tectonic disturbances below sea level. Incorrectly referred to as "tidal waves", tsunami travel at speeds of up to 800 km/h in the open ocean, where they are of low height. However, tsunami can rise to a height of 10m or more through the shoaling process as they approach land.

Seismic sea waves generated by a major disturbance of the sea floor and overlying water.

A series of travelling waves generated by the sudden displacement of the sea by submarine earthquakes, volcanic eruptions, landslides or asteroid impacts. The word ‘tsunami’ is Japanese for ‘harbour wave’.
