Atsunamiis a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespreaddestructionwhen they crash ashore.

·A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions. ... Out in the depths of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases.

Atsunami(fromJapanese:津波,lit.'harbour wave';[1]English pronunciation:/suːˈnɑːmi/soo-NAH-mee[2]or/tsuːˈnɑːmi/[3]) ortidal wave,[4]is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or alarge lake.Earthquakes,volcanic eruptionsand otherunderwater explosions(including detonations, landslides,glacier calvings,meteorite impactsand other disturbances) above or below water all have the potential to generate a tsunami.[5]Unlike normalocean waves, which are generated by wind, ortides, which are generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water.

Tsunami waves do not resemble normal undersea currents orsea wavesbecause their wavelength is far longer.[6]Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly risingtide.[7]For this reason, it is often referred to as a "tidal wave", although this usage is not favoured by the scientific community because it might give the false impression of a causal relationship between tides and tsunamis.[8]Tsunamis generally consist of a series of waves, withperiodsranging from minutes to hours, arriving in a so-called "internal wave train".[9]Wave heights of tens of metres can be generated by large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous, and they can affect entire ocean basins. The2004 Indian Ocean tsunamiwas among the deadliest natural disasters in human history, with at least 230,000 people killed or missing in 14 countries bordering theIndian Ocean.

A tsunami or tidal wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions above or below water all have the potential to generate a tsunami.
