Explicit Finite Diferences Methods (FDM) are used for numerical simulations in seismic problems. In these cases the medium is heterogeneous and for the guarantee of a precise and stable solution there is the need to use refined discretizations for spatial and temporal variables, resulting in large-scale problems. In this paper we present the explicit FDM for the wave equation in a heterogeneous domain and show the results through computer simulations.Los Métodos de Diferencias Finitas (MDF) explícitos son usados para simulaciones numéricas en problemas de sísmica. En estos casos el medio es heterogéneo y para la garantía de una solución precisa y estable hay la necesidad de utilizar discretizaciones refinadas para las variables espacial y t...
