Another option is to really simulate the shock that induces the tsunami, for
example by somehow raising the floor of your aquarium. See below for
inspiration (from http://wcatwc.arh.noaa.gov/physics.htm)

Earthquakes generate tsunamis when the sea floor abruptly deforms and
displaces the overlying water from its equilibrium position. Waves are
formed as the displaced water mass, which acts under the influence of
gravity, attempts to regain its equilibrium. The main factor which
determines the initial size of a tsunami is the amount of vertical sea
floor deformation. This is controlled by the earthquake's magnitude, depth,
fault characteristics and coincident slumping of sediments or secondary
faulting. Other features which influence the size of a tsunami along the
coast are the shoreline and bathymetric configuration, the velocity of the
sea floor deformation, the water depth near the earthquake source, and the
efficiency which energy is transferred from the earth's crust to the water
column.
