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.
The most common cause of tsunamis is an undersea earthquake that results in a sudden rise or fall of a section of the earth's crust under or near the ocean. This earthquake creates an explosive vertical motion that can displace the overlying water column, creating a rise or fall in the level of the ocean above. This rise or fall in sea level is the initial impulse that generates a tsunami wave. What type of earthquake generates a tsunami?
