They are called tectonic plates. See the related question below for more information about the causes of tsunami.
because it shifs the earths plates
Shifting of Tectonic Plates.
Tsunamis and plates are some what related in one way tsunamis are related by the change in the earths epicenter. a landslide is related in two ways by an focus and a fault line. plates are related an forming of mountains and the turning of the types of plates. Plates shifting causes earthquakes which can cause landslides or tsunamis.
Spredading of tectonic plates causes Tsunamis, Earthquakes, Volcanic erruptions, etc.
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.
Tsunamis are often caused by earthquakes in the sea. Earthquakes are caused by moving tectonic plates. So, indirectly, yes. See the related question below for more information on the causes of tsunami.
earthquakes can cause tsunamis because the earth's plates, (search up earth's plates on Google...) slowly move colliding against each other causing violent trembles known as earthquakes. because the ocean is covering the earth's plates up we cannot see that it is moving plates that are causing massive waves called "tsunamis." - by Sheenji- sheenjiberry@gmail.com
convergence
It can cause earthquakes, tsunamis, hurricanes, and other natural disasters depending on where you live.
the normal waves are produced due to the attractional or gravitational force between the earth and the moon but the tsunamis are caused due to the movement of the tectonic plates undet the ocean.
Tectonic plates moving, earthquakes. Tsunamis tend to be a combination. Otherwise there just tidal waves.
Earthquakes are one (but not the only) cause of tsunamis.
