A total of 469 3D components portable digital seismometers were deployed at 310 points along this profile to acquire active seismic signals detonated by 7 shots of 3000 kg and 10 shots of 500 kg explosive charge. These precious seismic data of high quality were employed to inverse the crustal P-wave velocity structure beneath the profile and a few basic features such as following were obtained:
