Popis:	Finite difference modelling of elastic wave fields is a practical method for elucidating features of records obtained for exploration seismic purposes, including surface waves. This has become possible because of the major increase in computing power available at reasonable cost. To take advantage of this power a 2D finite difference modelling program for elastic displacements has been written in Matlab. Two techniques for representing realistic boundaries are presented in some detail. Examples are provided of the program’s use to propagate waves at the surface of the earth through shallow lateral and vertical velocity changes. It can be seen that surface wave reflections and transmissions have similarities to body wave reflections and transmissions.
