Thanks. Also, why is the speed proportional to the depth? I understand that in order to lift a certain depth of water up a certain height, that you require a certain amount of energy. How does this energy transfer into speed? Is it a function of the speed at which the earthquake occurs (i.e, it moves the earth 10m in 0.05 seconds) or is it purely a wave phenomenon (in terms of wave mechanics) given the depth of fluid?

Hi,Dear Jonas, since the speed of tsunami is proportional to ocean depth, I found a question now. What's the maximum tsunami speed in water? I means just in a hydrodynamic model, we can assume whatever ocean depth we can. Is there any limitation for the transfermation speed of tsunami if ocean has an infinite depth? Could you tell me? Thanks!

i think tsunamis gain speed by fart made by sharks, whales, or even just fish. The farts combine and create a wall of smelly gas. as the gas rises quickly, so do the waves, and so, depending on the amount of creatures who have farted, a tsunami might be created. I know, I know its ingenius. But save your applause for when I am rich and famous for my discovery.
