The Fortran 90 program “pd_bimat.f90” calculates "phi", "r" and "z" components of motion in
two half-spaces, generated by a point dislocation with ramp source time function at the material
interface, based on the analytical solution given in the following papers:
1. Ben-Zion, Y., The response of two half spaces to point dislocations at the material interface,
Geophys. J. Int., 101, 507-528, 1990.
2. Ben-Zion, Y., Corrigendum to "The response of two half spaces to point dislocations at the
material interface" by Ben-Zion (1990), Geophys. J. Int., 137, 580-582, 1999.
The original codes were written by Yehuda Ben-Zion <email@example.com> in Fortran 77
("pd2hsp_corr.f", "pd2hsr_corr.f", "pd2hsz_corr.f") that calculate the "phi", "r" and "z"
components separately. Please see Fig 4 of Ben-Zion (1990) for the coordinate system employed.
