How is a tsunami different from a normal wave?

Answer 1

A tsunami is a HUGE wave created by a huge movement of the earth. Normal waves are small and cannot go further than 1 mile, while tsunamies can traverse the entire Earth more than one time. Usually, normal tidal waves are created by wind , sea currents and human development, while tsunamies are made by earthquakes, tectonical movements and, in very rare cases, the impact with a meteorite ( like the theory of the dinosaurs` death)

Answer 2

Tsunamis occur as a result of the movement of a huge volume of seawater from the seabed to the sea surface, where ocean waves are caused by the movement of wind over the sea surface. Compared to a normal wave, a tsunami has a much longer wavelength and so carries much more water, making them far more dangerous.

Answer 4

Hurricane waves are normal wind driven waves, just bigger.

Tsunamis are not wind driven and have a different structure. Tsunamis waves have influence all the way down to the ocean floor and have wavelengths of miles. When in open ocean they are not even noticeable and travel at hundreds of miles per hour. When they reach shore they slow down and build up, but still maintain an enormous wavelength so they carry much more water than a regular wave of the same height.

So while wind driven waves like those in hurricanes reach shore they wash in and out in a few seconds and don't come very far in. By contrast, when a tsunami hits it keeps coming in for up to fifteen minutes sometimes coming several miles inland.

Answer 5

A tsunami is usually caused by underwater seismic activity, such as an earthquake or volcano eruption, and can be much larger in size and have more destructive force than a normal wave. Tsunamis also travel at high speeds and can travel across entire ocean basins, posing a significant threat to coastal communities.

Answer 6

Ocean waves are a result of underwater earthguakes where as surface waves are due to the wind blowing over the ocean surface

Answer 7

For one thing, tsunami's are caused by underwater earthquakes and are way bigger in size than normal waves.

Answer 8

Nothing. They're just waves but larger.
