The seismicity observed on the latter includes recent historical events with magnitudes up to 6.5, and the one of the 12 05 2008 Ms 7.9 (Mo 1.15 1028 dyne/cm) thrust mechanism, so-called Sichuan earthquake. In this work, a hybrid procedure, combining long period and high frequency simulations (which for the low frequencies computations includes a recently optimized 3D seismic wave propagation parallel finite difference code) was used to obtain 3D synthetics seismograms for the mentioned Sichuan earthquake. The modeling included the USGS web-site, 40 x 315 km2 kinematic description of the earthquake´s rupture. The comparisons between observed and synthetic seismograms for stations sites of the Seismological Network of China, such as CD2 (Chengdu), GYA, LHZ and TIY at about 90, 500, 600 and 1200 Km from the epicenter of the Sichuan event, respectively, are satisfactory. Maximum synthetic accelerations, velocities and displacements, and permanent displacements of: 1.70 m/s2 ,
