A class of SEM has been widely used in the seismological field thanks to its capability of providing high accuracy and allowing the implementation of optimized parallel algorithms. In this contribution, the capabilities of SEM based GeoELSE code are illustrated, to deal with the seismic response of a 3D model of the sedimentary basin of Grenoble (French Alps). The model is excited by seismic waves originated by a strong motion scenario earthquake of MW = 6. Synthetic ground motions are calculated for all the recording sites prescribed in the framework of the ESG06 benchmark. The simulations take simultaneously into account the 3D topography of the area, the alluvial basin structure and the variation of mechanical properties throughout the valley.
