Seismic wave modeling for seismic imaging

摘要: Many scientific applications require accurate modeling of seismic wave propagation in complex media. These objectives can include fundamental understanding the Earth on a global scale, including fluid envelopes, mitigation risk with better quantitative estimates hazard, and improved exploitation natural resources crust Earth. Accurate quantification is continual quest, benchmark protocols have been designed for model definitions comparison solutions. Through this an impressive number numerical tools developed, ranging from efficient finite-difference methods to more sophisticated finite-element methods, so-called pseudospectral (see Wu Maupin review). The main motivation behind these permanent developments has improve efficiency accuracy forward modeling. To achieve this, one systematic choice both involved explicit time-stepping integration avoid matrix inversion...
