On the way in, they look like a series of waves, but usually really, really big ones. Depending on where you are, it could look like a massive wave or a wall of water coming rapidly your way.
On the way out, they almost don't even look like water sometimes because of all the debris they have picked up.
See the related link below for pictures of one particular tsunami and the aftermath.
i would say earthquakes but there are more reasons edit: Tidal waves are the byproduct of undersea plate tectonics. Subduction zones create large amounts of friction which then in turn create seismic waves which are transferred in to the surrounding sea water and take the form of fast moving waves in the open ocean. When the water becomes more shallow is when you see the classic images of a tsunami or tidal wave.
The Intertidal zone, Coastal Ocean, and the Open Ocean
The open water zone reaches down to where sunlight can still penetrate. Organisms that live here include tadpoles, fish, and non deep-rooted plants. Phytoplankton is the most abundant organism here.
An ocean is just a vast expanse or quantity of water. As a result of this explanation it seems that there is no difference between an ocean and a sea.The word Ocean derives from the Latin 'oceanus' and the Greek 'okeanus' which was thought to be a great river or sea surrounding the disk of the Earth. Oceanus was the son of Uranus and Gaia. This comes from early times when only the large land masses of Europe and Africa were known and the Ocean was an endless river that flowed around them. In later times the name was 'ocean sea' and later still when exploration discovered even larger bodies of water did the term 'ocean sea' divide into 'sea' for smaller bodies of water and 'ocean' for the largest There are now five Oceans, Atlantic, Pacific, Indian, Arctic and Antarctic
just look
None in the open ocean because in the open ocean the tsunami waves are not very large. They only build as they hit shallow water.

Most likely not. A whale in deep, open ocean water would probably not even notice a passing tsunami. In shallow water it would be a very stressful event.
Tsunamis in the open ocean are not dangerous at all; they aren't even noticeable. In deep ocean water a tsunamis is only a few feet to a few inches high and dozens of miles long. It is only when a tsunami reaches shallow water that it gains height.
Tsunami waves can occur in the middle of the ocean as a result of undersea earthquakes or landslides. These waves may not be as noticeable in open ocean areas due to their long wavelengths, but they can build up in height and strength as they approach coastal areas.
In open ocean, yes. A cheetah can move at 60 to 70 mph. A tsunami in open ocean can move at 500 to 600 mph.
Because width doesn't matter in a tsunami. The width is typically the length of the shore. It would be extremely difficult to classify a tsunami based upon height and width when the width is simply incomparable.
No. In open ocean a tsunami is hundreds of miles long and no more than a few feet high.
To a limited degree yes. If an earthquake of 6.5 magnitude or greater occurs underwater a tsunami watch is issued. If buoys detect the tsunami as it travels though open ocean a tsunami warning is issued.
Yes, tsunamis can be detected in the open ocean using buoys equipped with sensors that measure changes in water pressure. These buoys can transmit data to alert systems onshore, which can then issue warnings to coastal communities.
Yes, a large ship in the ocean will likely feel the effects of a tsunami passing underneath it, causing it to rise and fall with the passing wave. However, because of a ship's size and weight, it is less affected by tsunamis compared to smaller vessels. The crew might notice the ship rising and falling, but it is unlikely to cause significant damage to the ship itself.
