Detailed explanation-1: -Tsunamis (pronounced soo-ná-mees), also known as seismic sea waves (mistakenly called “tidal waves”), are a series of enormous waves created by an underwater disturbance such as an earthquake, landslide, volcanic eruption, or meteorite.

Detailed explanation-2: -Tsunamis are huge waves caused due to under sea disturbances inside the earth.

Detailed explanation-3: -Tsunami is a Japanese word that means ‘harbor waves’ as the harbors get destroyed whenever there is a tsunami. An earthquake, a volcanic eruption or underwater landslides can shift large amounts of ocean water. As a result tsunami occurs which may be as high as 15 m.

Detailed explanation-4: -The phenomenon we call tsunami is a series of large waves of extremely long wavelength and period usually generated by a violent, impulsive undersea disturbance or activity near the coast or in the ocean.

Detailed explanation-5: -A megatsunami is a tsunami with an initial wave amplitude (height) measured in many tens, hundreds, and possibly up to thousands of metres. A megatsunami is a separate class of event from an ordinary tsunami and is caused by different physical mechanisms.
