A tsunami is typically generated by vertical fault movement beneath the sea, particularly during underwater earthquakes. This movement occurs along subduction zones, where one tectonic plate is forced under another, causing significant displacement of water. The sudden uplift or drop of the ocean floor displaces large volumes of water, creating powerful waves that can travel across oceans. Other causes can include volcanic eruptions or underwater landslides, but tectonic activity is the most common source.
When an earthquake occurs under the ocean floor, it can cause a sudden vertical movement in the seafloor, displacing a large volume of water above. This displacement creates a series of waves that travel outward in all directions, forming a tsunami that can grow in height and speed as it approaches the shore.
Sea floor spreading is the process that creates new oceanic crust at mid-ocean ridges, which are underwater mountain ranges. As the new crust forms, it moves away from the ridge, pushing the existing ocean floor aside. This movement is what allows continents to drift apart from each other, as the forces generated by sea floor spreading contribute to the overall movement of tectonic plates.

Such a displacement of water could lead to a tsunami also known as a seismic sea wave.
A sudden vertical change in the sea floor during an earthquake can result in a tsunami. The movement of the sea floor displaces a large volume of water, which then forms powerful and destructive ocean waves that can travel long distances and cause widespread damage to coastal regions.
Sea cucumbers are creatures that can look like a vertical swimming caterpillar. Sea cucumbers generally live on the ocean floor.
An undersea earthquake causing a large displacement of the sea floor can cause a tsunamis. Another cause could be when a large area of cliffs suddenly crashes into the sea, so setting off a displacement of the sea.

Most tsunamis are generated from earthquakes at subduction zones, where one tectonic plate slide under another. During an earthquake at such a location, the subducting plate slips forward and part of it is thrust upwards, displacing the column of water above it. This displacement of water is what becomes the tsunami.
It was created on the sea floor.
A tsunami is a series of ocean waves generated by sudden displacements in the sea floor due to earthquakes, volcanic activity, or underwater explosions.
