The extended reflectivity method for synthetic near-field seismograms

In this study, the reflectivity method of seismogram synthesis is extended to compute near-field seismograms caused by a propagating fault. The complete representation of a point dislocation wave-field is made using Fuchs matrices and SH propagator matrices. The inversion of Fourier-Bessel transforms and fault surface integration are performed numerically using the complex frequency technique and some time-reducing devices. Numerical examples are presented which demonstrate the validity of the extension.
