The speed can be from winds, slopes, maybe because of the rate at which the ground moves in an earthquake, or the massive displacement from a landslide. These all are causes of why a tsunami can move so fast.

A little more...Tsunamis are not wind waves, and move much faster than wind waves, so the wind, slopes, etc. do not in fact make much difference in the overall Speed Over Ground (SOG) of a tsunami.

Instead, it's more related to wavelength. Tsunamis have a very small height or amplitude but a very long wavelength, and the math shows waves with long wavelengths travel faster.

The slippage of the earth, superfast asteroid or meteor strikes, localized, nuclear blasts, and the like can create tsunami waves. Wind doesn't.

In mid-ocean, where there's no friction against the bottom, a tsunami can travel roughly between 550-700MPH. As the bottom shallows, they slow down and pile up.

A tsunami is not a wind-related event, so the wind could be going any speed.

Why do tsunamis go so fast?

Tsunamis can travel at high speeds, often over 500 mph, because they are generated by large underwater earthquakes or volcanic eruptions that displace a massive amount of water rapidly. This rapid displacement creates long waves that travel across the ocean at high speeds with very long wavelengths.

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.
