Fig. 21

Seismic velocity structure along the lower seismic plane under northern Chile. Shown are across-arc vertical cross-sections of a–c P-wave velocity and d–f S-wave velocity beneath northern Chile. P- and S-wave velocities along three lines in the inset map are indicated by the color scales to the right. Earthquakes within a 20 km-wide section are plotted as dots. White lines denote the limit of resolution where the derivative weight sum is more than 10. (After Dorbath et al. 2008)
