Accuracy and Variability of Physics-based Ground Motion Modeling
Accurate velocity and rupture models are essential to estimate realistic ground motions for seismic hazard and risk analysis. This session welcomes submissions assessing the importance of various model features on the accuracy of predicted ground motions through physics-based numerical modeling. Examples include dynamic and kinematic rupture models, development, calibration and validation of community seismic velocity models, and quantification of the contribution of various model features to the ground motions. In addition to guidance on model features required for accurate mean predictions, we welcome physics-based contributions that aim to model realistic variability of the ground motions. Finally, studies on mapping of uncertainty in velocity and source models into the resulting ground motions are encouraged.
