A 2D modeling of the seismic response is obtained using modeling techniques that allow the computation of
synthetic seismograms, corresponding to two different seismic source models. The application of the modal
summation technique, extended to laterally heterogeneous structural models, to the area of Barquisimeto and
Cabudare allows us to create synthetic seismograms that can be used for the study of the local response along
of four profiles The calculation has been made by a hybrid method: Modal summation in the regional anelastic
mode (1D) where the source is located, and the finite difference in the local sedimentary structure (2D). The
realistic modeling of ground motion is a very important base of knowledge for the preparation of ground shaking
scenarios, as well as for the assessment of ground motion parameters for seismic microzonation.
