This book introduces a methodology for solving the seismic inverse problem using purely numerical solutions built on purely numerical solutions of 3D wave equations and is free of the approximations or simplifications that are common in classical seismic inversion methodologies and therefore applicable to arbitrary 3D geological media and seismic source models. Such waveform data contain a wealth of information about the details of the geological media and the seismic source, and the methodology introduced here allows us to exploit that information to the full extent. Source codes provided allow readers to experiment with the calculations demonstrated and also explore their own applications.

Über den Autor / die Autorin
Po Chen is an Associate Professor in the Department of Geology and Geophysics and the School of Energy Resources, University of Wyoming. He has published 24 peer-reviewed journal papers, 5 peer-reviewed conference papers, one book and three book chapters. Most of his publications are focused on different aspects of the newly emerging Full-3D Waveform Inversion (F3DWI) technique and its applications in earthquake hazard analysis/mitigation, resource exploration, crustal and upper-mantle dynamics. He teaches seismological inverse problems and has developed a set of parallel software tools for solving F3DWI problems.
En-jui Lee is currently an Assistant Professor at the Department of Earth Sciences, National Cheng Kung University, Taiwan. He has published six peer-reviewed journal papers and one book chapter on full-3D waveform inversion, including full-wave earthquake source inversions, waveform analysis tools for full-3D waveform inversions, optimized LSQR algorithm for large seismic tomographic inversions and potential applications of full-wave methods on seismic hazard analysis.
