May Rayleigh waves propagate with group- and phase-velocities of opposite sign in the valley of Mexico City?

On the basis of the group-velocity formula the occurrence of negative group velocities of Rayleigh waves is theoretically discussed for simplified models of Mexico City's basin by using results of a preceding article of the authors.
