:-) The bottom of the ocean going up (and down), i.e. earthquake, is
the major *cause* of Tsunami waves. Once set in motion, no further
movement of the bottom of the ocean is necessary. The energy in a
Tsunami wave extends all the way from the depth of the earthquake
source to the surface. Almost all of the water molecule movement in a
Tsunami wave is up and down. There is virtually no simple flow in a
Tsunami wave since the *energy* is traveling at hundreds of meters per
second.

"The measured tsunami flow velocities were within the range of 2 to 5 m/s. "
From: http://www.agu.org/journals/ABS/2006/2006GL026784.shtml

If it was "simple flow and not a wave" the energy in the wave
would be dissipated in accelerating the water molecules to a velocity
of hundreds of meters per second. Hint: Try making a spinning top out
of an unboiled egg.

It is like the soliton.
