Tsunamis
Tsunami is Japanese for harbour wave, with tsu meaning harbour and nami, wave. A tsunami is a sea wave or series of waves, often called a wave train, produced by a large disturbance of the sea floor that is of relatively short duration. Such disturbances cause the water column to move vertically and the resulting wave energy to spread outwards across the ocean at high speed (up to 950 kilometres per hour, the speed of a jet plane).
