How Fast Do Tsunamis Travel Across The Ocean. Once generated, a tsunami wave in the open ocean can travel with speeds greater than 800 kilometres an hour (500 miles an hour). Once a tsunami forms, its speed depends on the depth of the ocean.

As fast as a commercial jet • when the ocean is deep tsunamis can travel unnoticed on the surface at speeds up to 500 miles per hour (800 kilometers per hour), crossing the entire ocean in a day. The speed at which tsunamis travel depends on the ocean depth. Locally generated tsunamis can reach coastlines in just minutes.

In the deep ocean, a tsunami can move as fast as a jet plane, over 500 mph, and its wavelength, the distance from crest to crest, may be hundreds of miles. How do tsunamis travel across the sea? Tsunami nears land, loses speed, gains height. Once generated, a tsunami wave in the open ocean can travel with speeds greater than 800 kilometres an hour (500 miles an hour).
