tsunami wavelength

The wavelength of wind swell waves is much shorter than that of tsunami.



The wavelength of a tsunami is set by the width of sea floor deformation



in reproducing the effects of a tsunami is their super-long wavelength,



Regardless of their origin, tsunamis evolve through three overlapping but



proportional to its wavelength, tsunamis not only spread at high speeds,



only a few centimeters high but the wavelength around one kilometer.



The Tsunami Wave



Wavelength hundreds of miles. Speeds of 500 mph +. What causes Tsunami?



Consider again the 2004 tsunami: it had a wavelength of

Shallow-water waves (tsunami). Here the wavelength is much greater than the



Regular waves (caused by the wind) are very different from tsunami waves.



The depth and topography of the sea determines the form a tsunami wave takes



A tsunami is a series of waves of extremely long wavelength that are usually



Tsunami waves slowing, shortening, and heightening as they come ashore.
