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: -The correct answer is option 4 i.e Earthquake. Tsunami is a series of waves generated by violent seafloor movements associated with underwater earthquakes, meteorite impact, Landslides on the seafloor, volcanic eruptions, etc.

Detailed explanation-5: -A tsunami is a series of enormous waves created by an underwater disturbance usually associated with earthquakes occurring below or near the ocean.
