Abstract

A method to compute synthetic seismograms from a dislocation source in heterogeneous media by finite-difference techniques is presented. The model consists of a two-dimensional region in skew coordinates. With this technique it is possible to take into account the free surface and different geometric and kinematic characteristics of the source.
