Global synthetic seismograms using a 2-D finite-difference method
S U M M A R Y Two-dimensional (2-D) finite-difference (FD) synthetics, which fill the gap between fast 1-D analytic synthetics and time-consuming full 3-D synthetics in our ability to model seismograms, have been used in many studies. We address several issues involving 2-D FD methods in generating global synthetic seismograms. These include: (1) interfacing point source excitation for earthqua...
متن کاملFinite - Difference Seismograms for Sh Waves
The accuracy of the fi!lite-difference method for generating synthetic seismograms of SH wave propagation in cylindrically symmetric media is discussed. The finite-difference method has the advantage that arbitrary density and velocity fields in the medium may be specified. A point source is generated by a simple transformation of a line source. The accuracy of the finite-difference seismograms...

متن کاملFourth-order finite-difference P-W seismograms
I describe the properties of a fourth-order accurate space, second-order accurate time two-dimensional P-Sk’ finite-difference scheme based on the MadariagaVirieux staggered-grid formulation. The numerical scheme is developed from the first-order system of hyperbolic elastic equations of motion and constitutive laws expressed in particle velocities and stresses. The Madariaga-Virieux staggered-...
متن کاملReply to J. Vidale's "comment on 'a Comparison of Finite-difference and Fourier Method Calculations of Synthetic Seismograms'"
We wish to thank Dr. Vidale for his comment concerning the fourth-order finitedifference comparison used in our paper. He noted that our choice in using the implicit, fourth-order finite-difference method from McKee (1973) was not the most suited for comparison with the Fourier method in computational efficiency. Our choice in using the implicit method for comparison admittedly stemmed primaril...
