Session Time: 10:30 AM to 11:45 AM (local time)
Physics-based wave propagation simulations have the potential to quantify the contribution to ground motion estimates from individual features included in the modeling, such as basin edge effects, topographic scattering, nonlinear soil effects, small-scale heterogeneities, source effects and general 3D path effects. Such quantification is useful for understanding wave propagation as well as which features must be included to reproduce observed seismic records. This session welcomes submissions on physics-based numerical modeling of wave propagation, including studies focused on the dynamic or kinematic rupture models as well as development and validation of community seismic velocity models, and quantification of contributions from these model features on simulated ground motions.
