An enormous wave generated by an earthquake beneath the seafloor is known as a Tsunami.

Explanation:

When one or more waves are violently pushed by a force that makes them move vertically, a tsunami is formed.

This phenomenon can be generated by volcanoes, earthquakes, and even large explosions.

Water emerges from the depth in the form of a "whip" with sudden movements and can reach incredibly large heights.

While they are generated in the Ocean, they can travel several kilometers without losing their speed, and only lose speed when they approach the coast, which is where the ocean depth decreases.

Only large earthquakes produced on the seabed can cause a tsunami.
