About ground motion prediction equations selection

Ground motion prediction equations (GMPE) relate the strong ground shaking parameters to variables describing earthquake source, path, and on-site impact. From many available GMPEs, we select those models that are suitable for use in seismic hazard assessment take into account regional tectonic conditions. We present a GMPE selection procedure evaluates multidimensional trends (e.g., magnitude, distance, structural period), examines functional forms, quantitative performance tests versus independent data. Our recommendations include international simulation-based seismically active crustal regions, stable regions. To approximate epistemological uncertainties, process takes alternative representations of key attributes such as velocity attenuation over distance.
