WebDec 26, 2004 · The physics of a tsunami. Tsunamis can have wavelengths ranging from 10 to 500 km and wave periods of up to an hour. As a result of their long wavelengths, tsunamis act as shallow-water waves. A wave becomes a shallow-water wave when the wavelength is very large compared to the water depth. Shallow-water waves move at a speed, c, that is ... WebTsunamis are categorized as long waves; therefore, tsunami travel times can be computed with water depth as the only variable (Murty, T.S., Seismic Sea Waves Tsunamis, Bulletin 198). Long waves occur when the distance between wave crests is much greater than the water depth through which the wave is traveling. Wave speed is computed from the ...
