The speed of a tsunami differs between each. For instance, March 11th a tsunami hit Japan with a magnificent magnitude of 9.0. That triggered a tsunami with 10-metre-highwaves that reached the U.S coast.
Tsunami waves are long-period of sea produced by the sudden or abrupt movement of large volumes of water (it mostly occurs after earthquakes.) They can occur in lakes or in the seas.
Wave crests can surpass 100 kilometres (62 miles), and the wave period can vary from 5 minutes to 1 hour. The travel time depends on the water depth. Tsunami waves can be very long. They can be up to 60 miles (100 kilometres) and be as far as 1 hour apart.

∙ 13y agoThe speed of a tsunami can vary according to the energy it took to displace the water to cause the wave. Speeds of hundreds of miles an hour can be involved to move the wave deep in the ocean before it gets to the shallower sea bed.

How does wind speed affect tsunamis?
Wind does not affect tsunamis.
Does a tsunamis speed change based on water depth?

What speed can tsunamis reach?
A tsunami can reach from the sea and then it can sink the whole area to 1-1.5 miles away from the sea.
Tsunamis are what?
Tsunamis that are triggered by volcanic eruptions
How can we prevent tsunamis?
Tsunamis cannot be prevented.
How does wind speed affect tsunamis?
Wind does not affect tsunamis.
Do tsunamis increase in speed over open oceans?

How fast are tsunamis in miles per hour?
Tsunamis can travel close to the speed of sound. The most recent one traveled at about 200 mph.

What affects the speed of waves?
Surface winds and the sea bed movement of plates (these can cause tsunamis).
What speed can tsunamis reach?
A tsunami can reach from the sea and then it can sink the whole area to 1-1.5 miles away from the sea.
Does a tsunami go faster when the water is cold or warm?
There is no discernible difference in speed due to water temperature. The wave speed depends upon wavelength and the depth of the water for tsunamis at sea.
Tsunamis are what?
Tsunamis that are triggered by volcanic eruptions
How can we prevent tsunamis?
Tsunamis cannot be prevented.
What is the effect of the earthquake?
They cause tsunamis
How can tsunamis be prevented?
Unfortunately there is nothing we can do to prevent tsunamis.
Do tsunamis have jellyfish?
the tsunamis can carry jellyfish along
