N: 1. 1896, in reference to the one that struck Japan that year on June 15, from Japanese tsunami, from tsu “harbor” + nami “waves.”
2. 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. The tsunami wave may come gently ashore or may increase in height to become a fast moving wall of turbulent water several meters high.
Although a tsunami cannot be prevented, the impact of a tsunami can be mitigated through community preparedness, timely warnings, and effective response.
3. In Japanese tsunami means “harbour wave”; also called “seismic sea wave” or “tidal wave”. Catastrophic ocean wave, usually caused by a submarine earthquake, by an underwater or coastal landslide, or by the eruption of a volcano. The term “tidal wave” is frequently used for such a wave, but it is a misnomer, for the wave has no connection with the tides.
4. Seismic sea waves (mistakenly called “tidal waves”), which are a series of enormous waves created by an underwater disturbance such as an earthquake, landslide, volcanic eruption, or meteorite. A tsunami can move hundreds of miles per hour in the open ocean and smash into land with waves as high as 100 feet or more. (ITIC)
