Tsunamis are devastating phenomena that have the potential to ravage any coastline. The phenomenon also referred to as a seismic sea wave typically occurs as a series of large waves resulting from a disturbance emanating from beneath the ocean. The disturbance could occur due to an earthquake, meteorite, volcanic eruption, or landslide. Often, if a major earthquake or landslide happens close to the shore, the initial wave gets to the beach in minutes. Further, a tsunami can take hours to subside.
