An undersea earthquake displaces a vast amount of water in a sudden jolt. Huge shallow waves rush through the ocean at great speed. On reaching a gently sloping coastline the waves slow and compress upwards. Waves surge ashore to cause devastation well beyond the beach.
As a tsunami nears the shore, its speed decreases and its height increases, causing it to build up into a towering wave. This process is called shoaling. Once the tsunami reaches shallow water near the shoreline, the wave slows down further, causing it to amplify in height and potential destructive force.
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.
As tsunamis move towards shore, their speed decreases and their height increases due to the shallower water causing the wave to compress. This results in a dramatic increase in wave height and overwhelming force when the tsunami finally reaches the coast, causing devastating flooding and destruction.
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, a tsunami can lose power over time as it travels across the ocean due to factors such as friction with the ocean floor, energy dispersion, and interactions with land masses. However, tsunamis can still be destructive even if they lose some power before reaching the shore.

Tsunami
Coastal fishermen could be saved from a tsunami by taking their boats out to sea. A tsunami does not become particularly tall until lit reaches the shallow water near shore.
Waves are formed when water reaches the shore. Waves are created by the wind causing ripples on the water's surface, which amplify into larger waves as they approach the shore and break onto the beach.

No. A tsunami is highest in the shallow water near shore.
It disappears until the tsunami dies away. I don't know what happens to a tsunami but this is what I think.

You are safer in the middle of the ocean, where a tsunamis is barely even noticeable. It only becomes dangerous when it enters shallow water.
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.
