Earthquake Spectra· 2014Q1

Update of the Chiou and Youngs NGA Model for the Average Horizontal Component of Peak Ground Motion and Response Spectra

Brian Chiou, Robert Youngs

Short summary

An updated NGA-West2 model refines predictions for horizontal ground motion amplitudes from shallow crustal earthquakes, showing similar median predictions for M > 7 but lower for M < 5 compared to the 2008 model, with increased aleatory variability.
