How fast do tsunami waves travel across the open ocean?
about 20 km/h
about 100 km/h
up to 300 km/h
up to 800 km/h
Where the ocean is over 6,000 meters (3.7 miles) deep, unnoticed tsunami waves can travel at the speed of a commercial jet plane, over 800 km per hour (500 miles per hour). Tsunamis travel much slower in shallower coastal waters where their wave heights begin to increase dramatically.
