Answer 1

A tsunami is usually caused by an earthquake on the seafloor.

Step-by-step explanation:

A tsunami is typically caused by an earthquake on the seafloor. When an earthquake occurs, the energy is transmitted to the water above and causes the water to be displaced, resulting in a series of powerful waves known as a tsunami. Although tsunamis can also be triggered by other factors such as volcanic eruptions under the ocean or underwater landslides, the most common origin is an earthquake on the seafloor.
