I heard it was at least 500 mph while it was happening. Another Answer: 500 MPH is the commonly accepted speed of the energy wave in a tsunami in the open ocean. In this state â¦ , it typically only has an amplitude of a couple of feet. Most boats in the ocean will not even notice a tsunami as it goes past them. As it approachs land, however, it slows down and gains amplitude. This change depends on the topography of the ocean floor, but a typical approach speed is about 50 MPH with an amplitude closer to 30 to 60 feet, depending on the energy.
