Theoretical and Computational Seismology

Session ID#: 157711

Session Description:
Numerous recent advances in the Earth sciences are driven by developments in seismology, and specifically in numerical simulations, forward and inverse modeling theories, and growing computational resources. To promote further progress, this session offers a platform for theoretical and computational advances in seismology.

We welcome innovative contributions dealing with novel and creative approaches to more accurate and faster forward modeling, the efficient solution of (nonlinear) inverse problems, and methods that enable the exploitation of massive emerging data volumes. Of particular interest are contributions on the modeling and inversion of data from fiber-optic seismology, multi-scale or multi-parameter tomography, effective medium theory, uncertainty analysis in both data and model space, machine learning approaches to data mining and inversion, novel concepts in seismic interferometry, as well as the use of emerging hardware solutions, for example with the help of new programming languages.
