Question

summary for the tsunami

Answer 1

A tsunami or tidal wave, also known as a seismic sea 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, landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water.

Answer 2

Tsunami or tidal wave also known as a (seismic sea 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 Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Tsunamis generally consist of a series of waves, with periods ranging from minutes to hours, arriving in a so-called "internal wave train". The Ancient Greek historian Thucydidessuggested in his 5th century BC History of the Peloponnesian War that tsunamis were related to submarine earthquakes . but the understanding of tsunamis remained slim until the 20th century and much remains unknown. Major areas of current research include determining why some large earthquakes do not generate tsunamis while other smaller ones do; accurately forecasting the passage of tsunamis across the oceans; and forecasting how tsunami waves interact with shorelines.
