For someone who's on blogcation, you sure are posting some fascinating stuff. ;-)
I wonder what the physical basis for the nonuniformity is? The shape of the ocean floor?
CPP: The nonuniformity is caused by constructive & destructive interference of the waves, as well as by the shape of the seafloor. This animation from NOAA shows it really well: http://nctr.pmel.noaa.gov/chile20100227/20100227Chile.mov
