A tsunami is a series of water waves (called a tsunami wave train) that is caused when a largevolume of a body of water, such as an ocean, is rapidly displaced. The Japanese term is literally translated into “harbor wave.”
Earthquakes, volcanic eruptions and other underwater explosions (detonations of nuclear devices at sea), landslides and other mass movements, bolide impacts, and other disturbances above or below water all have the potential to generate a tsunami. Due to the immense volumes of water and energy involved, the effects of tsunamis can be devastating. (Click here for more details)
