| contents | Prograde Rayleigh-wave motion in the valley of Mexico Frank Wuttke Rodolfo Saragoni Peter G. Malischewsky Auning Cinna Lomnitz Ciencias de la Tierra Rayleigh waves valley of Mexico prograde particle motion 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 Rayleigh waves within a specific frequency band. Thecritical parameters for the existence of prograde motion are Poissons ratio in the layer and the shear-wave contrast between thelayer and the half-space. For high values of these parameters the range of frequencies featuring prograde motion falls approximatelybetween the site frequency and twice the site frequency. Particle motion can provide additional constraints for the inversion ofsurface-wave observations and H/V studies. 2006 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56845301 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.45 |
