it can be from 10 minutes to an hour or longer
Tsunami waves can vary significantly in length and width. The wavelength of a tsunami can range from a few kilometers to over 100 kilometers (about 60 miles) in deep water, while the wave height is typically less than a meter. As the tsunami approaches shallow coastal areas, the wave height can increase dramatically, often reaching several meters or more, while the wavelength decreases. The width of the wave can span hundreds of kilometers across the ocean.

The tsunami wave is so strong that it can crush the whole entire city.
A "tsunami" is not a land form, it is a wave.

A tsunami wave can be detected by a wave gauge and pressure monitors.

Not enough information to answer.
it is a range of different radiation with different wave length
a tsunami is a tidal wave caused by an underwater earthquake :]
Its still called a tsunami. There was a big Tsunami there in 1861/62

Tsunami do not have steps, they are a water wave.
