How does the depth of sea affect a tsunami?

Answer 1

The wave generated by a tsunami is really a large swell. Swells continue along until they meet the resistance of shallowing water. When the depth of the water can no longer handle the volume of water, the wave will rise up on top of the sand in shallower water and break. If the land form creates a gentle slope then the tsunami will appear as a very strong tidal flow. If the shore is steep then the swell will rise up and break against the beach. Most damage is not done by a large crashing wave, but by the sheer volume of water that is flowing onto the land and carrying debris along with it.

Answer 2

As a tsunami approaches shallow water, the force behind the wave becomes concentrated on a smaller area, which results in a higher pressure. The increased pressure forces the water up and thereby increases the size of the wave

Answer 3

As a tsunami approaches shallow water, the force behind the wave becomes concentrated on a smaller area, which results in a higher pressure. The increased pressure forces the water up and thereby increases the size of the wave.

Answer 4

The depth of the sea affects a tsunami by influencing the speed and height of the tsunami waves. In deeper waters, tsunami waves travel faster but with smaller amplitudes, while in shallower waters, the waves slow down and increase in height, potentially causing more damage when reaching the shore.

Answer 5

it effects the height of the tsunami if it is deep it is higher if very shallow very small
