Earthquakes: sea-quakes & tsunamis. Large shallow earthquakes generate the most destructive tsunamis where their epicentre is on a fault line along the ocean floor. Tectonic subduction and tectonic plate boundaries are the areas most likely to cause tsunamis. Collision of these tectonic plates in these areas of high seismicity cause large earthquakes as the plates move past each other, tilting, offsetting or displacing large areas of ocean floor from just a few kilometres up to 1,000 or more.
Tsunamis are formed by violent underwater earthquakes, landslides, volcanic eruptions, and, rarely, meteor impacts. These events cause sudden and drastic displacement of water, forming massive waves in the process. Most tsunamis are caused by earthquakes. As a result, most tsunamis occur near or at fault lines. When a tsunami is generated, it is not only 1 wave. Instead it is a series of waves, known as a wave train. These waves travel together and can be up to 1 hour apart. Tsunami waves travel extremely fast with speeds of up to 500 miles per hourâthe speed of a jet.
