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. where g is the acceleration due to gravity (= 9.8 m/s2) and H is the depth of water.
You cannot define the strongest tsunami, since tsunami's are the  result of earthquakes which have their own ranking. You can however  rank the biggest tsunami's, the bigges â¦ t tsunami ever recorded  happened in 1958 in Lituya Bay, Alaska. The wave was approximately  1720 feet tall.ou cannot define the strongest tsunami, since tsunami's are the  result of earthquakes which have their own ranking.
