A Comparative Analysis of Seismological and Gravimetric Crustal Thicknesses below the Andean Region with Flat Subduction of the Nazca Plate

Figure 1

Geological features in the study area. The black triangles show CHARGE seismic stations. Green lines indicate terrane boundaries. Shaded areas indicate major geologic features. Grey lines indicate the contours of the depth to the top of the subducted slab by Cahill and Isacks [3]. Extracted and modified after Heit et al. [11].
