Advancing Theoretical and Computational Seismology
Session ID#: 250834
Session Description:
Recent breakthroughs in Earth sciences are increasingly driven by the rapid evolution of computational capabilities and developments in seismology and in numerical simulations. This session offers a forum for presenting cutting-edge theoretical and computational developments, with a strong emphasis on global collaboration and the open exchange of knowledge. We invite innovative contributions that explore strategies for achieving more accurate and efficient forward modeling, robust solutions to (nonlinear) inverse problems, and scalable methods for handling the ever-growing volume of seismic data. Topics of particular interest include, but are not limited to, fiber-optic seismology, multi-scale and multi-parameter tomography, advances in effective medium theory, uncertainty analysis in both data and model space, machine learning approaches to data mining and modeling, seismic interferometry, and leveraging emerging hardware architectures and programming languages.By bringing together diverse perspectives and approaches, this session aims to foster discussions that will shape the future of theoretical and computational seismology.
