How are tsunamis measured and observed
WebTsunamis are waves set in motion by large and sudden forced displacements of sea water caused by submarine earthquakes, landslides, submarine volcanoes or asteroid impacts … 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.
