Detailed explanation-1: -Answer: Movements that occur on reverse faults result in Tsunamis often. Tsunamis occur due to earthquakes underneath or near the sea/ocean.
Detailed explanation-2: -Not all earthquakes generate tsunamis. To generate tsunamis, earthquakes must occur underneath or near the ocean, be large and create movements in the sea floor. A strike-slip fault where the movement of adjacent plates is primarily horizontal is not likely to cause a tsunami.
Detailed explanation-3: -A tsunami is a series of enormous waves created by an underwater disturbance usually associated with earthquakes occurring below or near the ocean. Volcanic eruptions, submarine landslides, and coastal rock falls can also generate a tsunami, as can a large asteroid impacting the ocean.
Detailed explanation-4: -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-5: -It should be noted that not all earthquakes generate tsunamis. Usually, it takes an earthquake with a Richter magnitude exceeding 7.5 to produce a destructive tsunami. Most tsunamis are generated by shallow, great earthquakes at subductions zones.
