A tsunami is a series of waves generated when water in a lake or the sea is rapidly displaced on a massive scale.

Earthquakes, landslides, volcanic eruptions and large meteorite impacts all have the potential to generate a tsunami.

Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water.
