How are tsunamis measured and observed
http://www.bom.gov.au/tsunami/info/ WebHow are tsunamis measured or observed? In the deep ocean, a tsunami has a small amplitude (less than 1 metre) but very long wavelength (hundreds of kilometres). This means that the slope, or steepness of the wave is very small, so it is practically undetectable to the human eye.
