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.
A tsunami is a huge wave, usually caused by volcanic or earthquake activity under the ocean, which can eventually crash onto the shoreline. The effects on a community can be devastating. What causes a tsunami? When an earthquake, volcano or landslide happens on the ocean floor, water is displaced. This water forms the start of the tsunami. When the waves reach shallower water: their height can increase by several metres; the shallow water slows the wave; the waves get closer together; It is hard to see that a tsunami is approaching. The most obvious sign is the coastal water retreats just before the waves reach the shore. This is actually the trough of the wave following behind.
