Physics-Based Earthquake Rupture Modeling and Strong Motion Simulations

Advancements in high-performance computing, improved understanding of physical processes during earthquake rupture and an increased number of observations of seismic events have contributed to the development of high-resolution seismic velocity models and numerical techniques for simulating earthquake ground motion for engineering applications. The integration of this multidisciplinary knowledge into fault-to-structure simulation techniques requires interaction between earth scientists and earthquake engineers. This session will focus on state-of-the-art research on kinematic and dynamic rupture modeling, computational aspects of ground motion modeling and verification of simulation techniques in building response analysis. We welcome studies focused on all aspects of physics-based earthquake rupture modeling and 3D wave propagation modeling, including: simulations incorporating free-surface topography, small-scale heterogeneity superimposed on deterministic velocity models, linear and non-linear constitutive material models, representation of near-surface geotechnical soil properties in site response, large-scale ground motion simulation on HPC platforms as well as simulations of ground motion variability and building response. Additionally, we encourage submissions related to implementing information from ground motion simulation research into targets for engineering constraints and their application in seismic hazard assessment, as well as theoretical and numerical modeling approaches addressing recordings with emerging sensor technologies such as DAS and rotational sensors.
