Many strange things happen, yet I think you asking about the sudden retreat from the water line prior to the event.
This also happens when we travel in a restricted waterway. The displacement of our ship recedes the water from shore only to return fast and high. We draw about 40 feet of water so that water is displaced to each side of the shoreline as we travel. An example is the Houston Ship Channel where warnings are posted at places like the Texas City Dike to warn swimmers and people fishing about the receding and then returning water.
Good Question and thanks for asking it.

How does the speed of tsunami wave change as it approaches the shore?
The wave would slow down as it approaches the shore.
How does the speed of the tsunami wave change as it approaches the shore?
The speed of a tsunami wave decreases as it approaches the shore due to the shallowing of the ocean floor, causing the wave to compress and slow down. However, the height of the wave may increase as the energy in the wave is concentrated, leading to higher waves onshore.
Will the water along a shoreline flow towards the sea just before a tsunami crashes on shore?
Yes, the water along a shoreline may recede just before a tsunami strikes, which is known as a "drawback". This phenomenon is due to the leading edge of the tsunami wave pulling water away from the shore as it approaches.
Can a tsunami bring sharks on shore?
Yes. All manners of marine animals can be brought on shore by a tsunami. Note, though that a shark brought on shore by a tsunami would be stressed enough that it would not be interested in eating.
Why do these changes occur when a tsunami wave is approaching the shore?
When a tsunami wave approaches the shore, two main changes occur: the water level rapidly decreases offshore as the wave pulls water toward it (causing the ebb phase) and then rapidly rises as the wave reaches the shore (causing the flow phase). This phenomenon is due to the displacement of water by the tsunami wave as it travels towards shallower waters.
How does the speed of tsunami wave change as it approaches the shore?
The wave would slow down as it approaches the shore.
How does the speed of a tsunami wave change as it approaches the shore?
As a tsunami wave approaches the shore, its speed decreases due to the wave energy being compressed into a smaller space. This leads to an increase in wave height and impact force when the tsunami hits the coastline.

The speed of a tsunami wave decreases as it approaches the shore due to the shallowing of the ocean floor, causing the wave to compress and slow down. However, the height of the wave may increase as the energy in the wave is concentrated, leading to higher waves onshore.
Is it true that an earthquake on the ocean floor can produce a tsunami which may grow into a huge wave as it approaches the shore?
Yes, an earthquake on the ocean floor can displace large amounts of water, causing a tsunami. As the tsunami wave approaches shallow water near the shore, it slows down and the height of the wave can increase significantly, resulting in a destructive surge of water reaching the coast.

Yes, the water along a shoreline may recede just before a tsunami strikes, which is known as a "drawback". This phenomenon is due to the leading edge of the tsunami wave pulling water away from the shore as it approaches.

Yes. All manners of marine animals can be brought on shore by a tsunami. Note, though that a shark brought on shore by a tsunami would be stressed enough that it would not be interested in eating.
Is a tsunami highest when its in the middle of the ocean?
No. A tsunami is highest in the shallow water near shore.

When a tsunami wave approaches the shore, two main changes occur: the water level rapidly decreases offshore as the wave pulls water toward it (causing the ebb phase) and then rapidly rises as the wave reaches the shore (causing the flow phase). This phenomenon is due to the displacement of water by the tsunami wave as it travels towards shallower waters.
What happens to a shore when a tsunami hits?
It disappears until the tsunami dies away. I don't know what happens to a tsunami but this is what I think.
What increases When a tsunami reaches shallow water?
When a tsunami reaches shallow water, its wave height increases significantly due to the reduction in water depth. As the tsunami approaches the shore, the energy of the wave is compressed into a smaller water column, causing the wave to rise dramatically. Additionally, the wave's speed decreases, contributing to the growing height and potential destructive power as it impacts coastal areas.
Is this true or false an earthquake on the ocean floor can produce a tsunami which may grow into a huge wave as it approaches the store?
True. An earthquake on the ocean floor can displace large volumes of water, generating a tsunami. As the tsunami travels toward shallower coastal waters, it can increase in height and intensity, potentially becoming a massive wave that can cause significant destruction upon reaching the shore.
Why did the Japan tsunami happen?
The 2011 Japan tsunami was triggered by a massive undersea earthquake with a magnitude of 9.0, causing a sudden uplift of the ocean floor. This abrupt movement displaced a large volume of water, resulting in the tsunami waves that devastated the coastline of Japan.
