Tsunami waves can travel any where from about 30 mph, to about 500 mph. seldom does a wave go above that range . IN THOSE TIMES they can to about 960 mph. What really matters is the depth of the body of water.
Many tsunamis can be very high and tall enough to destroy cities and towns. Some are as low and significant as a matter of mere centimetres. The highest tsunami ever recorded occurred in Lituya Bay, a large inlet on the coast of Alaska. It is believed that an earthquake of either 7.9 or 8.3 on the Richter scale, occurred along a nearby faultline, part of the Pacific Rim of Fire. Around 40 million cubic yards of dirt and glacier were shaken loose from a mountainside at the head of the Bay, resulting in a tsunami (series of waves), the highest of which reached over 5oo metres. Although the only witnesses to the event were a couple of fishing boats, the height was able to be determined by scientists finding the high water mark, where the water reached its highest point on the nearby land. This was the highest tsunami ever recorded. that means that higher ones could have easily occurred prior to written history, or where there were no witnesses, such as even more remote parts of Alaska.
Technically, the same as the wavelength of the Earth's tides, "thousands of km" if the trigger was big enough; such as a big enough, and/or fast enough, rock from space.
More practically, tsunamis are classified as such by their wavelength, often "hundreds of kilometres".

Up to 25 metres, according to calculations about the tsunami from Krakatoa.
Tsunamis vary from a foot or so to dozens of feet.
Most only go inland a few hundred yards. The most current one in Japan went in as far as six miles.
All the way around the world is possible, but most are limited to whatever ocean they start in.
The tsunami crested between 5 and 10 meters high (15-30 feet) with a few areas reporting 11 meters (33 feet).

It may possibly occur, but the chances are very slim. These are called Megatsunamis. The tallest tsunami wave ever recorded was the Lituya Bay tsunami in Alaska, which measured 1,720 ft. tall.
the tsunami hit alaska lity bay in july 9,1958 and the tsunami was about 1,720 feet tall
