Resum
We have estimated the P-wave velocity structure under the Northwestern South America Andean region (NWSAA) by applying a tomographic method to 5671 P-wave arrival times from 499 local events recorded by sixteen permanent seismic stations of the Seismological Network of Colombia (SNC) from December 1992 to June 1999. Seven layers at depths of 5.0 km, 15.0 km, 25.0 km, 40.0 km, 60.0 km, 80.0 km and 100.0 km were postulated to obtain the Vp structure along the plate boundary between the Nazca, Sou...
