Q How long does it take a tsunami to reach land? Once generated, a tsunami wave in the open ocean can travel with speeds greater than 800 kilometres an hour (500 miles an hour). These waves can travel across the Pacific Ocean in less than one day. Locally generated tsunamis can reach coastlines in just minutes.

Boats are safer from tsunami damage while in the deep ocean ( > 100 m) rather than moored in a harbor.
