Tsunami is caused due to:
1. Movement in seismic waves: Tsunamis can be triggered by the movement of seismic waves, which are generated by earthquakes or volcanic eruptions. When an earthquake occurs beneath the ocean floor, it can cause the entire water column above to be displaced, leading to the formation of a tsunami.
2. Displacement of tectonic plates: Tsunamis can also be caused by the displacement of tectonic plates. When two tectonic plates collide or slide past each other, it can create a sudden vertical movement in the Earth's crust, resulting in the displacement of a large amount of water and the formation of a tsunami.
3. Earthquake in the sea: Tsunamis are commonly associated with earthquakes that occur in the sea or near coastal areas. These underwater earthquakes can generate powerful tsunami waves that propagate across the ocean, causing devastation when they reach coastal regions.
4. Any of these: Tsunamis can be caused by any combination of the above factors. It is not uncommon for multiple factors to contribute to the formation of a tsunami, such as an earthquake triggering a volcanic eruption, which in turn leads to a tsunami.
In summary, tsunamis are primarily caused by the movement of seismic waves, the displacement of tectonic plates, and earthquakes in the sea. However, it is important to note that tsunamis can be complex events with multiple contributing factors.
