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.

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.

∙ 9y agoIn 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.

∙ 14y agoNormally 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.

∙ 11y agoIt 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.

∙ 10y agobecause 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

What makes tsunami more destructive?
IT depends on how hard the tech-tonic plates hit under water and how high the sea level is.
When continental crust and oceanic crust collide what happens?
it can cause earthquakes on the land and a tsunami plus if it hits hard enough it could possibly create a mountain in the water or as it is regularly called a island.
What is the temperature of a tsunami?
It can any temperature that would would commonly encounter in water on Earth. Tsunamis are not dependent on water temperature and in most cases, the circumstance surrounding them would not affect temperature.
What are the major effects of a tsunami?
there are many effects a tsunami can have on the locals and wildlife, many of these is rape. some people go rapeing others for enjoyment and others go rapeing animals for aids. they only do this under the water so others cant see what they are doing and the person/animal cant see either
How hard water Is produced?
You might be talking about ice but hard water is sourced from limescale rock and the limescale is in the water and that is what you get in your kettle when you dont filter the hard water.
Can a tsunami cause an oil spill?
maybe because if you think hard water can open many things
Why are nodules hard to mine?
Nodules are hard to mine because they are found in very deep water
Why it requires more soap when you bathe using deep well water?
You have hard water, and it possibly requires a softener.You have hard water, and it possibly requires a softener.
Does murky mean the same thing as deep?
No, "murky" means hard to see through. Deep water can be murky because it is often dark, but shallower water can also be murky if it is muddy.
What do bridges have that they are able to support cars?
they have poles that go deep in the mud and water that are very hard.
How often do tsunami's occur in the US?
It is hard to answer that question because a tsunami only happens when an earth quake happens near you.
Will i invent the tsunami gun?
If you are smart and work hard you may make something close to a tsunami gun, but if you're reading this in the future then yes. You could make a tsunami gun.
How do you get a hard mesh pocket to stay deep after you try to use a ball and butter knife to make it deep?
Soak it in warm water for about 30 sec. then store in a dry place.

How many was killed in tsunami in japan?
It's hard to answer the question.Victims are increasing continously.
What causes a tsunami answer with no hard words please?
Tsumamis are often caused by undersea earthquakes. The earthquake makes the ocean floor move, which causes the tsunami-wave.
When continental crust and oceanic crust collide what happens?
it can cause earthquakes on the land and a tsunami plus if it hits hard enough it could possibly create a mountain in the water or as it is regularly called a island.
