Generation of Vertically Incident Seismograms
註釋An algorithm for synthetic seismograms following the method of Kennett (1981) has been implemented in FORTRAN 77. Computations proceed in the frequency domain and then are Fourier inverted. Reflections of normally incident waves and their multiples are plotted on a Versatec plotter. The algorithm allows easy adjustment to other plotting protocols. A brief outline of the theory and a program listing (VISP) with examples are included. (Author).
