The most common underwater causes of tsunami are earthquakes and volcanoes. The event causes a large column of water to be displaced and moved out from the source. See the related question about the causes of tsunami for more detail about this question and about other causes of tsunami that may not start underwater.
If there is an Earth quake under the bed of the ocean and as a result the bottom is lifted upwards, then all of a sudden there is a whole heap of water being pushed upwards as well. If this happen on land the land would become higher and stay there, however when it happens to water it forms a wave as the surface of the ocean levels out again, this wave can have an enormous amount of water and force behind it depending on how much the seabed has lifted and can be bad news for any one on shore in its path.
Undersea earthquakes cause tsunamis because the ocean floor is moving which causes an extremly long wave yhat can travel across the ocean.
Tsunamis are caused when the seafloor has an Earthquake, it pushes the water up and forms a big wave (a tsunami).
They don't, earthquakes can cause tsunamis
because of the vibration coming from the earthquake "awakes" the ocean causing huge waves known as tsunamis
tectonics plates
No, the San Francisco earthquake of 1906 did not cause a tsunami.
An earthquake caused the tsunami!

No, the San Francisco earthquake of 1906 did not cause a tsunami.
An earthquake caused the tsunami!
No, the earthquake in the ocean cause the water to make the tsunami
The tsunami in Japan occurred because when the tectonic plates under ground move they cause an earthquake. Sometimes an earthquake can cause a tsunami from shaking underwater.
The cause of the earthquake was that the boundaries were sliding past each other and caused an earthquake in which resulted in a tsunami.
yes!

A volcanic eruption can cause an earthquake and an earthquake underwater can cause a tsunami.
