Ground-motion models, also called ground motion prediction equations (GMPEs) and sometimes attenuation relations, play a key role in seismic hazard assessments. These models provide an estimate of the earthquake ground motion to expect at a site given the occurrence of an earthquake at a particular location. Hundreds of GMPEs for different measures of earthquake ground motions (e.g. peak ground acceleration) and for different regions have been published since the 1960s. In this talk I will provide an overview of GMPEs, including a discussion of their inputs, outputs and derivation, as well as highlighting some of the challenges in their use.
