The height of a tsunami is primarily determined by the magnitude of the underwater disturbance that triggers it, such as an earthquake, volcanic eruption, or landslide. The depth of the water where the disturbance occurs also plays a critical role; shallower waters can amplify wave height. Additionally, the distance the tsunami travels and the topography of the coastline can influence its height as it approaches land. Finally, the initial energy released and the volume of water displaced contribute significantly to the tsunami’s overall size.
Thats a simple question it gets higher...
As a tsunami leaves the deep water of the open ocean and travels into the shallower water near the coast, it transforms. The tsunamis energy flux, which is dependent on both its wave speed and wave height, remains nearly constant. because of this shaoling effect, a tsunami, imperceptible at sea, may grow to be several meters or more in height near the coast. When it finally reaches the coast, a tsunami may appear as a rapidly rising or falling tide or a series of breaking waves.
Tsunamis can be generated by earthquakes, volcanic eruptions, or landslides underwater. The magnitude of the earthquake or the volume of material displaced by a volcanic eruption or landslide are important factors that determine the size and strength of the resulting tsunami.
In deep ocean water, the speed of a tsunami can exceed 500 mph but the wave height may be only a few feet. As the tsunami approaches shallow water and the sea floor rises, the speed decreases while the wave height increases significantly. This is why tsunamis can cause devastating flooding and destruction when they reach the coastline.
The Tsunami waves were around 10 meters (33 feet) high.AdditionallyThe tsunami waves were as high as 40.5 meters (133 ft) in Miyako.The tsunami was so powerful its waves traveled the entire Pacific ocean and were felt from the coasts of Alaska to that of Chile

The height of a tsunami increases as it gets closer to the shoreline. It sort of "rolls" up the sea floor, pushing itself higher as it does so.
When getting word of a tsunami, a cruise ship will head out to the deepest part of the ocean she can reach. In deep water, a tsunami may only be a couple of feet or even inches high. It is not until the tsunami reaches shallow water that the wave reaches any appreciable height. In fact, a cruise ship in the middle of the ocean may be the safest place to be during a tsunami.

The biggest tsunami occurred in 1958 (July 7) in Lituya Bay, Alaska. This tsunami reached a height of 524 metres, or 1700 feet.
In deep ocean water, the speed of a tsunami can exceed 500 mph but the wave height may be only a few feet. As the tsunami approaches shallow water and the sea floor rises, the speed decreases while the wave height increases significantly. This is why tsunamis can cause devastating flooding and destruction when they reach the coastline.

The usual measure of a tsunami is the height of the wave just as it reaches the beach.
Tsunami waves have a much longer wavelength in proportion to their height than ordinary waves do. They are often miles long.
