Fig. 5 Non-dimensional phase velocity of solitary magma waves in 1D
and 2D. The analytical solutions are taken from Barcilon and Lovera (1989).
The symbols give numerical results which assumed the CBA. The scaling of
the phase velocity is according to Barcilon and Lovera (1989), to transform
to the scaling law used here, the velocities have to be multiplied with
0n-1 Rm/Rtn. The porosity amplitude is defined as may/ 0, where
0 is the background porosity.
