A Comparative Analysis of Seismological and Gravimetric Crustal Thicknesses below the Andean Region with Flat Subduction of the Nazca Plate
Figure 3
East-west section between latitudes 30º and 31º south, coincident with the CHARGE project seismic stations, with the results of the gravimetric and seismic modeling. (a) The present day topographic elevation (brown) and the elevation predicted from the seismic Moho (grey). (b) The gravimetric effect of the Nazca plate (red) calculated from the Grow and Bowin densities [14]. (c) The gravimetric Bouguer anomaly corrected for the gravimetric effect of the Nazca plate and the gravity effect of the Airy isostatic root. (d) The gravimetric inversion (full black line), the isostatic roots (red dotted line), and the seismic depths obtained from Fromm et al. [12] are represented by blue colored diamonds. (e) The effective elastic thickness calculated according to Braitenberg et al. [50], Wienecke et al. [51].
