In the open ocean, tsunami wave heights are often relatively low, typically ranging from 1 to 3 feet (0.3 to 1 meter) and can be difficult to detect. However, these waves travel at high speeds of up to 500-600 miles per hour (800-965 kilometers per hour). As they approach shallower coastal waters, their height can increase dramatically, sometimes reaching heights of over 100 feet (30 meters) or more, causing significant destruction upon landfall.

Why are tsunami waves in the open ocean limited in height?
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.
How dangerous are tsunami in the open ocean and why?
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.
How does the speed and wave height vary according to the depth of the ocean when there is a tsunami?
In deep ocean water, the speed of a tsunami can exceed 500 mph but the wave height may be only a few feet. As the tsunami approaches shallow water and the sea floor rises, the speed decreases while the wave height increases significantly. This is why tsunamis can cause devastating flooding and destruction when they reach the coastline.
When a tsunami hits the shore it can be very destructive because of its?

Do tsunami waves occur in the middle of the ocean?
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.

Why is a tsunami smaller when it begins at than when it reaches the shoreline?
As a tsunami travels across the ocean, it is in deeper water where its energy is spread out over a larger area, causing the wave height to be lower. As the tsunami approaches shallower waters near the shoreline, the wave slows down and the energy becomes concentrated, leading to an increase in wave height.
Do tsunami waves occur in the middle of the ocean?
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.
What is a powerful ocean wave that causes great destruction?
A tsunami
If tsunami is for an ocean wave what would the wave be called for Lake Baikal?
Its still called a tsunami. There was a big Tsunami there in 1861/62
How can a tsunami occur?
As a tsunami leaves the deep water of the open ocean and travels into the shallower water near the coast, it transforms. The tsunamis energy flux, which is dependent on both its wave speed and wave height, remains nearly constant. because of this shaoling effect, a tsunami, imperceptible at sea, may grow to be several meters or more in height near the coast. When it finally reaches the coast, a tsunami may appear as a rapidly rising or falling tide or a series of breaking waves.
What is a large wave created by an earthquake on the ocean floor?
A tsunami is an ocean wave caused by an earthquake.It is not a tidal wave.
