摘要: We present the results of simulation seismic wave propagation in complex geological media through numerical calculation, estimating 2D/1D soil response by generating synthetic seismograms. This corresponds to along 2D sections basin prepared using local and regional geophysical information. The hybrid methods technique was applied, that uses analytical (modal summation surface waves) (finite differences) obtain seismograms up a frequency 10 Hz, 8 north-south south-north profiles, 3 east-west profiles crossing sedimentary Guarenas-Guatire. Three scenario earthquake were chosen, located along:San Sebastian, Pichao (system La Victoria) Tacagua Faults, with magnitudes 7, 6 5 Mw, respectively. following ground motion parameters obtained : spectral ratio horizontal vertical components H/V, acceleration spectrum for transverse, radial components. Response spectra developed from averages relations (considered as transfer functions) at bedrock hazard study.
