Why is it hard to regognise a tsunami in deep water?

Answer 1

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.

Answer 2

In the deep open ocean a tsunami is usually only a few feet high and many miles long. The small rise and fall in water level over the course of several minutes would go unnoticed by anyone in a boat. The tsunami does not become noticeable until it slows down and gains height in shallow water.

Answer 3

Normally the ocean water pulls back out unusually far so that is one sign that means run or get to a high place. Also if there is a generally large earthquake and you are standing near the ocean it is probably best to prepare. But a tsunami isn't always a large sea wave, sometimes it is a big push of water or a flood. There is a low chance you will survive either on at sea level ground.

Answer 4

It caused by a underground earthquake or a regular earthquake. It shakes the ocean then it travels in the water. Not on top of the water, where you can see it.. Also when the ocean gets more shallow, you can start to see the wave clearly. Then it goes over the city.

Answer 5

Tsunamis are less noticeable in deep water because they have long wavelengths and low amplitudes. This means that the wave height may be only a few centimeters in deep water, making it difficult to detect visually or by boat. Additionally, tsunamis can travel at high speeds in deep water, further reducing the time available for detection before they reach shallow Coastlines.

Answer 6

because it has to hit the bank of a beach to form into a wave,before this it is just a wave of moving water travelling very fast
