Geomorphology Characterization of Ica Basin and Its Influence on the Dynamic Response of Soils for Urban Seismic Hazards in Ica, Peru

Figure 5

The left panels show the dispersion curves obtained with multichannel analysis of surface waves (MASW; top) and multichannel analysis of microtremors (MAM; bottom) methods. Here the averages and their inversions allow us to determine the velocity profile. The central plots show the velocity models (top) for the three linear arrays (bottom). The validation of the results is shown in the plots to the right. The inversion allowed us to obtain a theoretical transfer function (FTT; black line), which is superposed to the empirical transfer function (FTE; blue line) and shows a good correlation (degree of correspondence) with the fundamental frequency defined by the vertical gray line.
