Analysis of Site-Response Residuals from Empirical Ground-Motion Models to Account for Observed Sedimentary Basin Effects in Wellington, New Zealand
de la Torre, Chris; Bradley, Brendon; Lee, Robin; Tiwari, Ayushi; Wotherspoon, Liam; Kaiser, Anna (2024-04-09)Analysis of prediction-observation residuals from the empirical ground motion models (GMMs) used in the 2022 New Zealand National Seismic Hazard Model (NZ NSHM) update indicates a general underprediction of ground motions ... -
Comparing alternative methods to account for shallow site effects in hybrid broadband ground-motion simulations
Kuncar, Felipe; Bradley, Brendon; de la Torre, Christopher; Rodriguez-Marek, Adrian; Zhu, Chuanbin; Lee, Robin (2024-04-09)Shallow site effects are usually not explicitly modelled in hybrid broadband ground-motion simulations, and their proper incorporation may be key to improving prediction at soil sites. This paper examines five methods to ... -
Nationwide investigation of systematic site effects in New Zealand: Residual analysis of physics-based ground motion simulations
Tiwari, Ayushi; Bradley, Brendon; de la Torre, Christopher; Lee, Robin (2024-04-09)This study examines systematic site effects from the prediction residuals of physics-based ground motion simulations using a dataset of small magnitude (3.5 ≤ Mw ≤ 5.0) active shallow crustal earthquakes recorded in New ... -
New Zealand National Seismic Hazard Model Revision 2022: Hazard changes with respect to NZ NSHM 2010
Bora, Sanjay; Bradley, Brendon; Di Caprio, Chris; Gerstenberger, Matt; Howell, Andy; Nicol, Andy; Van Dissen, Russ (2024-04-09)Revision of New Zealand National Seismic Hazard Model (NZ NSHM 2022) represents a significant change not only in hazard results but also in terms of methods and processes in comparison to NZ NSHM 2010. The changes span ... -
Towards 3D ground motion simulation-based site amplification: a Wellington case study considering multiple basin geometries
Lee, Robin; Bradley, Brendon; Hill, Matthew; de la Torre, Christopher; Kaiser, Anna; Wotherspoon, Liam (2024-04-09)This paper presents a study on 3D ground motion simulation-based site amplification using the Wellington region of New Zealand as a case study. Several recent models of the Wellington sedimentary basin have been developed ...
