Abstract
This volume contains twelve documented copies of computer programs dealing with surface wave propagation in a plane layered medium, to be used in earthquake seismology. The programs have been designed so that the output of one is compatible with the input of another program. These programs are presently operating on a Honeywell 6023 and are free of machine dependent peculiarities, with a few exceptions listed in the introduction. Although most programs require an offline CALCOMP drum plotter, in more recent programs plotting calls are performed in modular subroutine units to facilitate conversion to other plotting systems. The CALCOMP subroutines are listed. Most of the programs consist of a statement of purpose, input/output, program units, description or theory, the actual program, sample data, and sample output. The program titles are: SURFACE, REIGEN, LEIGEN, EIGEN, MODEL, NONPRP, EXCIT, SRFWVPLT, SRFWVSRC, RADPAT, QUESTION, and WIGGLE.
