The answer is.... quite 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.
One went from Krakatoa in Indonesia to England. They can move as fast as a commercial jet plane.
Tsunamis can travel as fast as jet planes over deep ocean waters, reaching speeds of up to 500-600 miles per hour (800-1000 kilometers per hour). However, as they approach shallow waters near coastlines, their speed decreases, causing the height of the wave to increase dramatically.
In order for a Tsunami to form a large amount of water in the ocean has to be displaced. When an Earthquake occurs under the sea (due to the sudden release of pressure between tectonic plates) the sea bed moves causing water to be displaced. As the water rushes upwards it creates a series of large waves, Tsunami waves which travel extremely fast and can be devastating upon coastal cities.
Tsunamis mostly occur in the Pacific Ocean's "Ring of Fire," where tectonic plate movements are frequent. Countries such as Japan, Indonesia, and Chile are particularly prone to tsunamis due to their proximity to tectonic plate boundaries and underwater earthquakes.
Tsunamis can travel close to the speed of sound. The most recent one traveled at about 200 mph.

quite fast
Tsunamis can travel at speeds of up to 500 to 600 miles per hour (800 to 970 kilometers per hour) in the open ocean, which is comparable to the speed of a jet plane. However, their speed decreases as they approach shallow waters near coastlines, causing them to slow down and increase in height.

20 mph
No they tend to prefer fast currents than the the sea (deep water) like rivers.
In very deep, open water, tsunamis are often undetected by ships that they pass beneath. That's the safe way to be in a boat during a tsunami. Near shore, where the water becomes much shallower, boats can be bad places to be, as the wave-front rears above the surface. If you had adequate warning that a tsunami was approaching, one way to stay safe would be to get in your (fast) boat and get out to deep water. Otherwise, run inland as fast as you can.
3400mph
The speed of a wave depends on the medium it is moving through. In general, sound waves travel at around 340 m/s in air, electromagnetic waves (such as light) travel at 300,000 km/s in a vacuum, and ocean waves can travel as fast as 750 km/h in deep water during a storm.
Water waves can travel at different speeds depending on factors such as wind speed, wave height, and water depth. In deep water, wave speeds typically range from 10 to 50 kilometers per hour. Shallow water waves tend to move slower than those in deeper water.
