Present and Future Directions in Earthquake-induced Ground Motion Modelling: Implications for Seismic Design and Assessment
Earthquake-induced ground motion prediction is presently under-going a paradigm shift from the empirical prediction of ground motion intensity measures (e.g. response spectra), based on regression analysis of observations from past earthquakes, toward the use of physics-based simulation methods that directly predict the ground motion time series – a focus of QuakeCoRE Flagship 1. The implications on present and near-future approaches for undertaking seismic hazard analysis, the prescription of ground motion loading for seismic design standards, and the ability to revolutionize the analysis of earthquake-induced impacts more broadly are examined. Examples from the 2010-2011 Canterbury and 2016 Kaikōura earthquakes are used for context.
