Deep ocean tsunamis travel as fast as jet planes

In the open ocean, a tsunami is nearly invisible to the naked eye, often rising just a few centimeters above the surface. However, because its wavelength can stretch up to 200 kilometers, the wave isn't just a surface ripple; it involves the entire water column from the air down to the seafloor. This massive volume of water allows the energy to move at roughly 800 kilometers per hour.
