GEM-PEER Task 3 Project : Selection of a Global Set of Ground Motion Prediction Equations

Abstract : Ground-motion prediction equations (GMPEs) relate a ground-motion parameter (e.g., peak ground acceleration, PGA) to a set of explanatory variables describing the earthquake source, wave propagation path and local site conditions. In the past five decades many hundreds of GMPEs for the prediction of PGA and linear elastic response spectral ordinates (e.g., pseudospectral acceleration, PSA) have been published. The Global Earthquake Model (GEM) Global GMPEs project, coordinated by the Pacific Earthquake Engineering Research Center (PEER), brought together ground-motion experts from various institutions around the world to develop recommendations on what GMPEs should be used by GEM when conducting global seismic hazard assessments. The GEM-PEER Project has seven tasks, as listed below: Task 1a Defining a Consistent Strategy for Modeling Ground Motions Task 1b Estimating Site Effects in Parametric Ground Motion Models Task 2 Compile and Critically Review GMPEs Task 3 Selection of a Global Set of GMPEs Task 4 Include Near-Fault Effects Task 5 Build an Inventory of Recorded Waveform Databases Task 6 Design the Specifications to Compile a Global Database of Soil Classification This report presents the methodology used in, and results of, Task 3, Selection of a Global Set of GMPEs. The reports of the other tasks of the GEM-PEER project are published by the GEM foundation and posted at: http://www.globalquakemodel.org.
