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 ... -
Applicability of existing CPT-Vs correlations to direct-push crosshole and cone penetration test data for shallow Holocene-aged New Zealand soil deposits
Zhou, Hui; Wotherspoon, Liam; Stolte, Andrew; McGann, Christopher (2024-04-09)A number of empirical correlations have been proposed to estimate shear wave velocity (Vs) using cone penetration test (CPT) data as a result of the growing availability of global databases. The performance of four existing ... -
Multi-scenario approach for the assessment of liquefaction exposure and impact across New Zealand State Highways
Lin, Amelia; Wotherspoon, Liam; Zorn, Conrad (2024-04-09)Events such as the 2010-2011 Canterbury Earthquake Sequence or the 2016 Kaikōura earthquake demonstrated the impacts of liquefaction and lateral spreading across New Zealand infrastructure networks. Statistical liquefaction ... -
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 ... -
Tsunami resilience: Aotearoa New Zealand's path to integrated risk management and engineering design
Johnston, David; Tan, Marion; Tapuke, Kelvin; Toma, Charlotte; Stephens, Max; Wotherspoon, Liam; Leonard, Graham; Power, William; Adikari, Kasuni (2024-04-09)Tsunami threats persist along coastlines worldwide, necessitating proactive measures to safeguard lives and property. Recent catastrophic events, such as the 2004 Indian Ocean tsunami and the 2011 Japan tsunami, have ...
