wHaT cAuSiNg tSuNaMi?


Although there is no calculated volume of water that constitutes a standardized quantity that will generate a tsunami, the amount displaced must be significant enough to create waves underwater in the vast ocean. Waves are formed as the displaced water mass moves under the influence of gravity to regain its equilibrium and radiates across the ocean like ripples on a pond. The larger the displacement, the larger the wave generated.
A tsunami can be generated by four general ways:


  • Undersea earthquake

  • Landslide

  • Volcanic eruption

  • Extraterrestrial collision.

A tsunami is a wave train, or series of waves, generated in a body of water by an impulsive disturbance that vertically displaces the water column. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis. Tsunamis can savagely attack coastlines, causing devastating property damage and loss of life.
