It is a simple flow not a wave. :-) 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. S* -- 73, Cecil, w5dxp.com ah, grabbed another non-sequitar term to add to your gibberish now? for how long will everything be a soliton to you? |
