how does the seafloors topography affect the amplitude of a tsunami
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.
