1. Seismic tomography with P- and S-waves for the study of the upper mantle in Brazil / Tomografia sísmica com ondas P e S para o estudo do manto superior no Brasil
We used travel time seismic tomography to study the upper mantle beneath SE and Central Brazil. This method is based on the inversion of P- and S-wave relative travel time residuals (VanDecar, 1991) obtained from more than 80 stations in an area of 20 x 20 degrees. More than 11000 P and PKP residuals, and more than 8000 S, ScS, SKS, and SKKS residuals were o
