[duylqkrz] tsunami energy

of the total amount of energy released in an earthquake, e.g. 2011 Japan, how much of it goes into the tsunami?

unlike building collapse, where the energy of the destruction is partially supplied (as potential energy) by the building builders, in tsunami seems demonstrated the earthquake's raw power (actually energy): the energy to lift all that water had to come from somewhere.

actually this is incorrect: one can harvest the potential energy from making a trough into making a crest.

inspiration: consider building a tsunami simulator, scaling up wave pools seen at amusement parks.  how much energy would it need?  of course, depends on pool size.
