Moczo P., Kristek J., Halada L. The Finite-Difference Method for Seismologists: An Introduction

Bratislava: Comenius University Bratislava. – 2004. – 160 p. The primary goal of the presented text is to provide basics of the finite-difference method and its application to the numerical modeling of seismic wave propagation and earthquake motion. The text was written for participants of the Research and Training Workshop of the Marie Curie Research Training Network SPICE held in Venice, Italy, September 25 – October 2, 2004. It may be useful also for seismologists who are not familiar with the finite-difference method, or those who are interested in some particular topics explained and analyzed in the text. This introduction covers neither all aspects of the finite-difference method nor all applications of the method in seismology. It is focused primarily on the 1D problem. The 1D problem itself is not fully analyzed. The references probably do not include all relevant contributions, though we tried to include many of them. It is important to realize that the understanding of the 1D problem is just the beginning. It is, however, important and useful because it considerably helps in learning the full 3D problem. The text also contains a user’s guide to the FORTRAN 95 program package 1DFD which is intended as a training tool for beginners in development and application of the finite-difference method. Numerical examples – model configurations, input data, and results – are also included. Though the text is introductory, it includes some material which probably cannot be found elsewhere.1D Elastic Problem
