Large tsunamis can even move across entire oceans. Tsunamis move at great … WebDec 22, 2004 · The propagation constant for the average or coherent wave is complex even for a nondissipative medium, because the coherent wave is continually scattered by the inhomogeneities and converted into the incoherent wave. The propagation velocity of the average wave is also diminished by the inhomogeneities.
