Resumen:
The seismic potential of southern China is associated with the collision between the Indian and the Eurasian plates. This is manifested in the western Sichuan Plateau by several seismically active systems of faults, such as the Longmen Shan. The seismicity observed on the Longmen Shan fault includes recent events with magnitudes of up to 6.5, and the one of 12 May 2008 M-w 7.9 Wenchuan earthquake. Herewith, as part of an ongoing research program, a recently optimized three-dimensional (3D) seismic wave propagation parallel finite-difference code was used to obtain low-frequency (<= 0.3 Hz) 3D synthetic seismograms for the Wenchuan earthquake. The code was run on KanBalam (Universidad Nacional Autonoma de Mexico, Mexico) and HECToR (UK National Supercomputing Service) supercomputers. The modeling included the U. S. Geological Survey 40 x 315 km(2) kinematic description of the earthquake's rupture, embedded in a 2400 x 1600 x 300 km(3) physical domain, spatially discretized at 1 km in th
