GEOLOGY

Detailed explanation-1: -A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.

Detailed explanation-2: -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-3: -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-4: -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.

Detailed explanation-5: -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.
