  We examine the capability of a blast-wave scenario -associated to a coronal
flare or to the expansion of CME flanks- to reproduce a chromospheric Moreton
phenomenon. We also simulate the Moreton event of December 06, 2006 considering
both the corona and the chromosphere. To obtain a sufficiently strong coronal
shock -able to generate a detectable chromospheric Moreton wave- a relatively
low magnetic field intensity is required, in comparison with the active region
values. Employing reasonable coronal constraints, we show that a flare ignited
blast-wave or the expansion of the CME flanks emulated as an instantaneous or a
temporal piston model, respectively, are capable to reproduce the observations.
