S43G:
Theoretical and Computational Frontiers in Seismic Tomography I

Submit an Abstract to this Session



Session ID#: 32839

Session Description:
This session offers a platform to present advances in seismic tomography, with focus on developments that contribute to the improved resolution of 3D Earth structure at all scales. Of special interest are theoretical and computational developments in tomography, as well as methods that enable the exploitation of new massive data volumes from dense networks around the globe. Possible contributions include novel forward modeling techniques, advances in seismic interferometry for static and time-variable Earth structure, inversion and nonlinear optimization techniques, innovative approaches to uncertainty analysis, machine learning and large-scale data analysis.
