Development and implications of an expanded national earthquake catalogue for New Zealand
Hutchinson, Jesse; Lee, Robin; Bradley, Brendon; Van Houtte, Chris; Kaiser, Anna; Wotherspoon, Liam (2021-04-14)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 ... -
Full Waveform Tomography for the upper South Island region, New Zealand
Nguyen, Trung Dung; Bradley, Brendon; Lee, Robin; Graves, Robert (2021-04-14)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 ... -
Ground motion simulation validation with explicit uncertainty incorporation for small magnitude earthquakes in New Zealand
Neill, Sarah; Lee, Robin; Bradley, Brendon (2021-04-14)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, ... -
Source modelling insights from ground motion simulation validation of moderate magnitude active shallow crustal earthquakes in New Zealand
Lee, Robin; Bradley, Brendon; Graves, Robert; Paterson, James; Motha, Jason (2021-04-14)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 ... -
Validation of NZ small-magnitude ground-motion simulations using complex structural systems
Loghman, Vahid; Bradley, Brendon; Chandramohan, Reagan; Lee, Robin; McGann, Christopher (2021-04-14)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 ... -
Wellington basin amplification: research goals and update from the National Seismic Hazard Model Programme
Kaiser, Anna; Hill, Matt; Wotherspoon, Liam; Bradley, Brendon; Lee, Robin; Roten, Daniel; Bourguignon, Sandra; Pancha, Aasha; Gerstenberger, Matt (2021-04-14)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 ...
