Tsunamis start with an earthquake beneath the ocean bed. There is a sudden massive and very powerful movement of seabed upward/downward. When this happens the entire column of water above the location of the quake moves. This is one thing that distinguishes a tsunami from an ordinary wave. Ordinary waves may affect water for a few meters down from the surface, but a tsunami is the movement of the entire water column from surface to ocean floor.
This surge of water moves outward in all directions. Where the water gets deeper, the energy is dissipated somewhat, but where the water is more shallow, the energy is concentrated again. This is why when the wave hits land there is a tremendous concentration of energy.
Tsunami is caused by earthquakes in the ocean,
They don't really erupt in the same way as a volcano erupts. Tsunamis are a large wave of water that forms when the sea floor jumps up suddenly due to tectonic plate movements.
The sea.
earthquakes along the ocean floor
Landslides and other big impacts like volcanic eruptions cause mega tsunamis
Tsunamis are caused by the sudden movement in water by tectonic plates. Tsunamis are a result of Earthquakes.
Tsunamis are caused by shifts in tectonic plates in the middle of the ocean. Once they come ashore, tsunamis can cause millions of dollars in property damage.
usually and underwater volcano.
earthquakes are the most things that cause a tsunamis
tsunamis come from a disturbance in the water like a volcanic erruption which causes the water to draw back creating a huge wave
The pacific plate slides across the North American plate for example, which causes tsunamis to form do to underwater earthquakes
Landslides and other big impacts like volcanic eruptions cause mega tsunamis
What causes the tsunami is an earthquake under ground and it blows the water to land
The mass of the wavefront causes most of the damage.

Tsunamis are geologic in origin. Typically they are triggered by earthquakes, but other causes can include landslides and volcanic eruptions.
