Regionally-Adjustable Generic Ground-Motion Prediction Equation, Emrah Yenier
Electronic Thesis and Dissertation Repository
We develop a simulation-based generic ground-motion prediction equation (GMPE) that can be adjusted for use in any region by simple modifications to its key modeling parameters.
First, we determine how to treat ground-motion saturation effects observed at close distances to large magnitude earthquakes in a point-source sense. We model the source and attenuation attributes of well-recorded M ≥ 6 events, considering ground motions originate from an equivalent point source placed at an overall effective distance such that the empirically-observed saturation effects are successfully reproduced. We investigate the trade-offs between source and attenuation modeling parameters through analysis of Fourier amplitudes for …
