How far inland can a tsunami go? Quick Answer. With wave speeds that can reach as much as 435 miles per hour, a tsunami can travel as far inland as 10 miles, depending on the slope and the shape of the shoreline that it is traveling across.
A small tsunami wave typically reaches only 30 centimeters high, but it can become a huge wave that reaches 30 meters high as it strikes the shore. The effects of a tsunami are further magnified when a lagoon, harbor or bay funnels the waves as the waves move inland. Tsunamis can rise to more than 100 feet.
