A tsunami is underwater, therefore, it will only look like the sea bulges out 2-3 inches. However, before a tsunami strikes, the shoreline will retreat drastically. Then, as the tsunami wave nears the shore, it starts to get taller as the seabed gets shallower.

Another Answer

A tsunami is the landfall byproduct of a large pressure wave propagating through a body of water. An underwater landslide will create a pressure wave as the mass of the landslide moves from one location to another. As the mass is in motion, the pressure of the water in front of the mass is increased while the pressure of the water behind the mass is decreased. The whole body of water this is taking place in reacts by back filling the mass in motion. This causes the propagation of a pressure wave away from the source.

When the wave is traveling through the ocean, the volumn of the whole body of water is so much greater than the relativly small amount of water involved in the wave propagation, that the variation in height at the surface is relativly shallow. The propagating wave can be seen, but it takes a very high point of view with very sensitive height measuring instruments.

Why can't kelp live in muddy or deep waters?

1) Kelp, being vegetation needs sunlight to grow, hence why if it made its way into muddy or deep water where sunlight is hard to come by it would sease to grow and would die out. 2) In certain circumstances the conditions in muddy or deep water result in less oxygen/nutrients etc so again the organism would find it hard to grow.
