[/Also do tsusami all have the same frequency? QUOTE]
Am unsure what your earlier questions are...but answer is NO to this part...in general they differ in frequency and of course amplitude.
I think maybe you are wondering something about how the mass of water displaced in a tsunami is related to the size of the wave created. yes it is...your statement
For example, dropping a small versus large mass into a liquid, and in comparison to 10 mile diameter meteor impact in ocean. Amplitude would seem to scale in regards to mass; why might not part of energy be distributed into frequency?
seems accurate, but the "frequency" depends on the speed of displacement and the density of the liquid, right?...and other factors.
See here:
http://en.wikipedia.org/wiki/Tsunami#Characteristics
to start: look at the animatied illustration to the right...you can see DEPTH affects frequency...also many different mechanisms can create a tsunami...see the description of tsunami's in oceans...lakes...seismic activity...cliffs falling into water...etc...
Scientists hunting for evidence of gravitational waves have to guess at the approximate magnitude and frequency of waves...guess at phenomena originating them...in order to design detector apparatus.
Maybe this helps??:
