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.
An active plate margin is an actual plate boundary, where oceanic crust and continental crust crash into each other. Active plate margins are often the site of earthquakes and volcanoes. Oceanic crust created by seafloor spreading in the East Pacific Rise, for instance, may become part of the Ring of Fire, the horseshoe-shaped pattern of volcanoes and earthquake zones around the Pacific ocean basin.
