This study assesses the need to consider complex structural models in ground-motion simulation validation. It develops a novel statistical framework to quantify the proportion of the differences in structural responses ...

In the last two decades, New Zealand (NZ) has experienced significant earthquakes, including the 2010 M 7.2 Darfield, 2011 M 6.2 Christchurch, and 2016 M 7.8 Kaikōura events. Amongst these large events, tens of thousands ...

This study investigates the uncertainty of simulated earthquake ground motions for small-magnitude events (Mw 3.5 – 5) in Canterbury, New Zealand. 148 events were simulated with specified uncertainties in: event magnitude, ...

Hybrid broadband ground motion simulation validation has been an ongoing effort in NZ with recent studies focussed on active shallow crustal earthquakes of large magnitude (Mw>7.0) and small magnitude (3.5<Mw≤5.0).  Lessons ...

This paper examines various boundary condition assumptions for modelling 2D geotechnical site response, which requires a more sophisticated treatment of the boundary and loading conditions than what is typically required ...

In Wellington, 3D basin amplification effects observed at 1 – 2 second spectral periods were identified as one factor likely to have exacerbated damage to mid-rise structures during the 2016 Mw 7.8 Kaikōura earthquake ...

In this paper, we apply Full Waveform Tomography (FWT) based on the Adjoint-Wavefield (AW) method to iteratively invert an existing 3-D geophysical velocity model for the upper South Island region, New Zealand. Through the ...
