Scientists have known for years that the shape of the seafloor plays a role in how tsunami waves build up as they approach the coastline.Underwater topography also determines why some areas get hit worse than others.But in the wake of the Tohoku-oki tsunami, scientists now know that seafloor topography affects the strength and height of a tsunami even in the deep ocean and at great distances from the genesis of the wave.cientists have known for years that the shape of the seafloor plays a role in how tsunami waves build up as they approach the coastline.
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.
