The speed of sound
If its wavelength is 50 meters with a period of 6.5 seconds it means it is traveling at 50 meters every 6.5 seconds or 50/6.5 = 7.7 meters/sec.

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.

Period = wavelength/speed
Wave speed = (wavelength)/(period)
Period = (1) divided by (frequency) = (wavelength) divided by (speed)Frequency = (1) divided by (period) = (speed) divided by (period)Speed = (wavelength) times (frequency) = (wavelength) divided by (period)Wavelength = (speed) divided by (frequency) = (speed) times (period)
the frequncy of the 2005 tsunami was 1,403 hz
Wavelength*Frequency = Velocity of the wave. or Wavelength/Period = Velocity of the wave.
Period = Wavelength / Velocity
"A tsunami, also called seismic sea wave or tidal wave, is a catastrophic ocean wave, usually caused by a submarine earthquake occurring less than 50 km (30 miles) beneath the seafloor, with a magnitude greater than 6.5 on the Richter scale. Underwater or coastal landslides or volcanic eruptions also may cause a tsunami. The term tidal wave is more frequently used for such a wave, but it is a misnomer, for the wave has no connection with the tides. A tsunami can have a wavelength in excess of 100 km and period on the order of one hour. Because it has such a long wavelength, a tsunami is a shallow-water wave. Shallow-water waves move with a speed equal to the square root of the product of the acceleration of gravity and the water depth."Problem:In the Pacific Ocean the typical water depth is about 4000 m. What is the speed of a tsunami with a wavelength of 50 km. Solution: 50km is much larger than 8000m = 8km. We have a shallow-water wave.
Wavelength is the distance between two successive crests or troughs in a wave. And time period is the time taken for the disturbance to move from one crest to the successive one. So wavelength/ wave period (time period) = speed of the wave.
Just divide the wavelength by the wave period, and you've got the wave speed.
