what type of plate boundary is most likely to generate a tsunami?
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.
