MALISCHEWSKY, Peter G.  y  FORBRIGER, Thomas. May Rayleigh waves propagate with group- and phase-velocities of opposite sign in the valley of Mexico city?. Geofís. Intl [online]. 2020, vol.59, n.2, pp.101-104.  Epub 02-Oct-2020. ISSN 2954-436X.

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.
