Project Description

The Fortran 90 code "sh2qs_ld.f" calculates SH displacement seismogram at a given receiver
location in a structure consisting of 2 quarter spaces. The motion is generated by an SH line
dislocation with a step source time function at the material interface. The calculations are based on
the analytical solution described in the paper:

Ben-Zion, Y., The response of two joined quarter spaces to SH line sources located at the material
discontinuity interface, Geophys. J. Int., 98, 213-222, 1989

The code can be complied with most Fortran 90 compilers. The Geometry of the problem is specified in Fig. 9 of Ben-Zion (1989).
