Source to site seismic ground motion prediction on an earth dam

Abstract

The seismic ground motion is driven by the equation of motion, which depends on several parameters describing the earthquake source, the wave travel path, and the site of interest. We propose in this study to understand the relative importance of three shear wave velocities through a model combining global geophysical measurements with numerical simulations to estimate synthetic seismic motions sensitivity. Global sensitivity analysis (GSA) involves the identification and quantification of parameters contributions to output variability.
