Derivation of New Equations for Estimation of Earthquake Induced Peak Ground Acceleration and Velocity

In this study, a new method called M5, was employed to derive ground-motion prediction equations (GMPEs). Peak ground acceleration (PGA) and peak ground velocity (PGV) was formulated by seismic parameters including earthquake magnitude, earthquake source to site distance, average shear-wave velocity and faulting mechanisms with The Pacific Earthquake Engineering Research Center (PEER) database. For verification, the proposed model was compared with three well-known models by Correlation Coefficient, Root Mean Square Error and Mean Absolute Error. A sensitivity analysis and a parametric analysis was carried out to determine the contributions of the parameters affecting model and sensitivity of the models to the variations of the influencing parameters. The equations are remarkably simple and can reliably be used for pre-design purposes.
