Detailed explanation-1: -What is a tsunami? 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: -By far, the most destructive tsunamis are generated from large, shallow earthquakes with an epicenter or fault line near or on the ocean floor. These usually occur in regions of the earth characterized by tectonic subduction along tectonic plate boundaries.
Detailed explanation-4: -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-5: -Tsunamis are ocean waves triggered by:Large earthquakes that occur near or under the oceanVolcanic eruptionsSubmarine landslidesOnshore landslides in which large volumes of debris fall into the water Scientists do not use the term “tidal wave” because these waves are not caused by tides.
