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 with observations in the valley of Mexico. We compute synthetic seismograms for a simplified model of the Texcoco site. The earthquake of 19 September 1985, M 8.1, featured prograde motion of...

We compute synthetic seismograms for a simplified model of the Texcoco site. The earthquake of 19 September 1985, M 8.1, featured prograde motion of Rayleigh waves within a specific frequency band.

F. Se calculan sismogramas teóricos para un modelo simplificado de la red de Texcoco. Para el sismograma de las estaciónes TACY, CU01 y SXVI del 19 septiembre de 1985 se obtiene movimiento prógrado de Rayleigh dentro de un rango de frecuencias. Los parámetros críticos para la existencia de movimiento progrado son el módulo de Poisson en la capa superficial y el contraste de velocidades de ondas S entre la capa y el semi–espacio. Para valores altos de estos parámetros el rango de movimiento progrado se encuentra aproximadamente entre la frecuencia del sitio y el doble de la misma. Adicionalmente, la zona de movimiento progrado también se presenta en dependencia en estos parámetros críticos. El estudio del movimiento de la partícula rinde constreñimiento adicional invirtiendo parámetros de modelo de las observaciones de las ondas superficiales en general y H/V estudios en especial.Universidad Nacional Autónoma de México.

| description |
A theory of prograde particle motion of Rayleigh waves for a layer over a half–space is derived and compared with observations in the valley of Mexico. We compute synthetic seismograms for a simplified model of the Texcoco site. The earthquake of 19 September 1985, M 8.1, featured prograde motion of Rayleigh waves within a specific frequency band. The critical parameters for the existence of prograde motion are Poisson's ratio in the layer and the shear–wave contrast between the layer and the half–space. For high values of these parameters the range of frequencies featuring prograde motion falls approximately between the site frequency and twice the site frequency. Particle motion can provide additional constraints for the inversion of surf ace–wave observations and H/V studies. |
