Prograde Rayleigh-wave motion in the valley of Mexico

A theory of prograde particle motion of Rayleigh waves for a layer over a half-space is derived and compared withobservations in the valley of Mexico. We compute synthetic seismograms for a simplified model of the Texcoco site. Theearthquake of 19 September 1985, M 8.1, featured prograde motion of R...
