Beschreibung:
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.
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.
Connects FWI and conventional tomography with imaging techniques used in seismic inversions and in other scientific/engineering disciplines such as medical imaging, remote sensing, etc.
