Frontiers in Theoretical and Computational Seismology
Session ID#: 74617
Session Description:
Numerous recent advances in seismology have been driven by developments in numerical simulations, forward and inverse modeling theories, and rapidly growing high-performance computers. To promote further progress, this session offers a platform for theoretical and computational advances in seismology.
Of general interest are novel and creative approaches to more accurate and complete forward modeling, the efficient solution of (nonlinear) inverse problems for wavefield sources and Earth structure, and methods that enable the exploitation of massive emerging data volumes. In particular, we welcome innovative contributions on the joint inversion of disparate datasets, multi-scale and/or multi-parameter tomography, full-waveform inversion, homogenization and effective medium theory, uncertainty and resolution analysis, machine learning, and novel concepts in seismic interferometry for static and time-variable Earth structure.
