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.
When the speed of the wave approaches zero, the wave breaks, much of its energy is released and it will not go too much further. A tsunami that reaches a height of 300 feet when it rears up at the shore, will lose energy as it travels inland. Itâs all about energy.
