Estudio de Relaciones Espectrales V/H Asociado al Sistema de Fallas de Quito

Abstract

The Quito city is on a system of inverse blind failures, neotectonic model considers five fault segments extending approximately along 60 km., However you do not have adequate knowledge of seismic hazard associated with this system failures for the vertical component of ground motion. In this study, we will determine spectral ratios V/H models using strong ground motion for the Next Generation Attenuation (NGA WEST2) that are applicable for crustal tectonic regime as the city of Quito program; in principle it is considered the city divided into five zones: south, south-central, central, north central and northern subsequently considered distances Rrup = 5 km, 10 km, 15 km, 20 km, 30 km and for each one are calculated spectral ratios V/H.
