Tsunamis are long-wavelength ocean waves caused by the sudden displacement of large volumes of water. Most are triggered by undersea earthquakes, but volcanic eruptions, landslides, and meteor impacts can also generate them. Unlike normal wind-driven waves, tsunamis move through the entire water column, allowing them to travel at jet-aircraft speeds across deep oceans. In open water they may be barely noticeable, but as they reach shallow coastlines, the waves slow down, compress, and dramatically increase in height—releasing enormous energy onshore. #OceanScience #WaveDynamics #EarthProcesses #SeismicEvents #CoastalPhysics This video was generated using AI for visualisation purposes and is not a recording of a real event.
