What can be speed of tsunami on the mainland?
800km/h
Which is faster - the average speed of tsunami sometime called a tidal wave or the top speed of a cheetah?
The top speed of a tsunami is 900 kilometers per hour (600 mi/hr) and the top speed of a cheetah is 120 kilometers per hour (75 mi/hr). Therefore, the average speed of a tsunami is faster than the top speed of a cheetah.
What is the speed of a tsunami with a wavelength of 225 kilometers and a period of 15 minutes?
The speed of a tsunami can be calculated using the formula: speed = wavelength / period. In this case, the speed would be 225 km / 15 min = 15 km/min.
Does a tsunami speed up as it approaches land?
Yes, a tsunami can speed up as it approaches shallower waters near the coast due to the conservation of energy principle. This can cause the height of the wave to increase, making it more destructive when it reaches land.
How soon can a tsunami appear after a tsunami?
There are tsunamis and there are tsunami trains. A tsunami is generated by an underwater earthquake. A new tsunami has to wait for a new earthquake. It is not uncommon for any earthquake to be followed by one or more aftershocks within a matter of hours or days, so a new tsunami can result similarly. Since earthquake behavior is notoriously unpredictable, so is tsunami generation. A single tsunami results in a series of waves with periods ranging from minutes to hours. This is called the tsunami "wave train". There is more information in the related links.
