Effect of Hikurangi subduction interface geometry on simulated ground motion intensities (2020)
The Hikurangi subduction zone lies under the eastern side of the North Island and has a large down dip curvature (Williams et al. 2013). The six current Hikurangi fault rupture scenarios provided by the National Seismic Hazard Model (NSHM) all provide for a planar fault geometry that is adopted in predictions using both empirical ground-motion models (GMMs) and also prior simulations performed by the authors. In this poster, the effect of more realistically representing the curved geometry in the source description, and its influence on simulated ground motions is examined.
