In order to study seismic wave propagation through laterally varying
sea floor structures, a software package has been created to generate synthetic
seismograms by finite differences. The elastic wave equation can be
solved in two dimensions either for point sources in cylindrical coordinates
or for line sources in rectangular coordinates. Vertical and radial variations
of the elastic parameters are allowed.
The package includes four programs. Input to the system consists of a
short file containing parameter values to describe the model. The first program
is used to initialize the system for the particular model being used.
The source arrays and velocity matrices are each computed by a separate program.
The final program, which actually carries out the finite difference
calculations, includes six subroutines to implement different options based on
alternative finite difference formulations. Two different kinds of output
files are created by this program: one or more snap-shot files, and one time
series file, which will usually include more than one series.

Calculation of 3-dimensional synthetic seismograms on the connection machine
Allen, Julie M.; Burns, D. R. (Woods Hole Oceanographic Institution, 1989-10)A three dimensional, second order finite difference method was used to create synthetic seismograms for elastic wave propagation in heterogeneous media. These synthetic seismograms are used to model rough seafloor, the ... -

Hunt, Mary M.; Stephen, Ralph A. (Woods Hole Oceanographic Institution, 1986-11)Over the past eight years, a software package has been developed to solve the elastic wave equation by the method of finite differences (Hunt et al., 1983; Stephen, 1983; Stephen, 1984a; Stephen, 1984b; Nicoletis, 1981). ...
