## How do tsunami waves travel?

A tsunami is made up of a series of very long waves. The waves will travel outward on the surface of the ocean in all directions away from the source area, much like the ripples caused by throwing a rock into a pond. As the waves approach the coast, their wavelength decreases and wave height increases.

## How do you calculate tsunami travel time?

Calculating Time to Affected LocationsOnce you know the distance, multiply by the speed of the tsunami to find out how long you have before the tsunami strikes. Distance (meters)/ Speed (m/second) = time until tsunami (seconds) State your final answer in hours, minutes and seconds.
