Tsunami . .

As a tsunami leaves the deep water of the open ocean and travels into the shallower water . A tsunami travels at a speed that is related to the water depth . As the water depth decreases, the tsunami slows. The tsunami's energy flux, which is dependent on both its wave speed and wave height, remains nearly constant. Consequently, as the tsunami's speed diminishes as it travels into shallower water, its height grows. Because of this shoaling effect, a tsunami, imperceptible at sea, may grow to be several meters or more in height near the coast. When it finally reaches the coast, a tsunami may appear as a rapidly rising or falling tide.

They can travel at about 600 km an hour across deep oceans (as fast as some jet planes), and can be 10-30 meters high when they reach land.

Tsunami is a Japanese word with the English translation, "harbor wave."
