Resum: Simulations are playing an increasingly important role in seismological research. High-quality synthetic seismograms are required to better constrain Earth models by comparison with observed data. Furthermore, numerical experiments allow for a better understanding of wave propagation phenomena as well as the seismogenic processes happening at active faults. Although synthetic seismograms can be obtained easily for simplified soil models (e.g. flat topogaphies or layered elastic media) the Earth shows a large degree of complexity at all scales. New methodologies, as the discontinuous Galerkin (DG) method, aim at increasing the flexibility of our numerical simulations without compromising the accuracy of the results. The DG method is capable of honoring complex geological structures and topography, as well as including the effects of viscoelastic, anisotropic or poroelastic media on the propagation of seismic waves.
