Ground motion simulation validation with explicit uncertainty incorporation for small magnitude earthquakes in New Zealand (2020)
This study explicitly includes source, path and site uncertainties into physics-based ground motion simulations, in order to account for: inherent modelling restrictions, ground motion randomness and modelling errors. These uncertainties are propagated through the model to produce a range of realisations for a given intensity measure, site and event. Once validated, these probabilistic distributions will provide a more reliable prediction of possible ground motions. Figure 1 illustrates an example of a deterministic and probabilistic response spectra.
