It actually displaces the water, which generates the energy for the tsunami. If you imaging the length of the fault, x the displacement (8ft) all of the displaced water does not go into the crust.

it is a subduction zone, and water circulates down into the earth (crust and mantle) as the ocean floor is subducted under Japan, but it is mostly in the pore spaces of the sediment on the ocean floor and in the cracks in the underlying rocks..

but.. caveat.. I'm a glacial/coastal guy.. not a seismologist!

what are they gonna do with this enormous amount of debris?

i mean they are an ISLAND and allot of the material was imported
over many years so that means huge Barges and euks trucks hauling it where
to the ocean? China wont touch it now that it's radio active.

So is the speed of the tsunami, english meaning is death wave, like a wave going thr speed of sound minus the friction caused by the water itself.
