Tidal Waves, or "Tsunamis", are created when a large mass of earth on the
bottom of the ocean floor drops or rises, displacing a column of water
above it. This movement on the ocean floor can be caused by
earthquakes, underwater landslides or impact collisions from space. Below
is a list of some of the largest Tidal Waves ever recorded.
