Future Directions in Physics-based Ground-motion Modeling in Preparation for the Fall 2023 Meeting
Modern ground-motion modeling for improved source physics and hazard understanding has been investigated from both simulation-based and data-driven perspectives for quantitative prediction. Significant recent advances in empirical modeling move towards spatially varying, non-ergodic models, while physics-based simulations are broadening their applicability to regions or faults not previously considered. The community needs to move forward together to ensure that these models are realistic and applicable to a larger range of magnitudes of different types of events. To this end, SSA, joint with SSJ, will host a topical meeting entitled "Modern Global Ground-Motion Modeling: Future Directions in Physics-Based Ground-Motion Modeling" in fall 2023. At this meeting, we will bring together international researchers to exchange ideas, compare approaches, and delineate new directions of research for the next decade in the field of physics-based ground-motion modeling and prediction. The conference will be held in Vancouver, Canada on October 9 to 12, 2023.
This session is designed as an opportunity to discuss the current status of research on ground motion modeling and make the most effective foci for the discussion during the Fall 2023 Ground Motion meeting. Therefore, this session seeks contributions that elucidate the impact of the new approaches for source and site effects representation on the ground motions and the associated seismic hazard evaluations. Example topics of interest/areas of study include, but are not limited to: evolution and limitations of complex kinematic and dynamic source modeling; new approaches to the modeling of the empirical source characteristics; physical and empirical modeling of site effects; comparisons of physics-based and empirical data-driven approach on the overall prediction accuracy; and, statistical evaluation of the variability of our evaluations and predictions.
