Modeling Seafloor Deformation and Ground Motion For Subduction Zone Earthquakes
In order to perform Bayesian inference for earthquake source parameters based on sparse observational data, one must have a reliable forward model. In this case, we require a robust and efficient way to calculate the seafloor deformation resulting from an earthquake (which causes the tsunami), and a similarly effective way to calculate ground-motion at a distance, due to propogating seismic waves. Here, we discuss the Okada model for seafloor deformation, as well as several empirical models for ground motion. We discuss the limitations of the ground motion models, and suggest approaches that may prove useful in the future.
