Session ID#: 49111

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 general theoretical and computational advances in seismology.

Of general interest are novel and creative developments towards more accurate and complete forward modeling and (nonlinear) inversion, and methods enabling the exploitation of massive emerging data volumes. In particular, we welcome innovative contributions on topcis such as multi-scale tomography, homogenization and effective medium theory, uncertainty and resolution analysis, machine learning, or novel concepts in seismic interferometry for static and time-variable Earth structure.
