There has been a long-identified need in New Zealand for a community-developed three-dimensional fault model that is accessible and available to all. Over the past year, work has progressed on building and parameterising ...

The New Zealand National Seismic Hazard Model (NSHM) is being updated for the first time since 2010 in a multi-institutional project led by GNS Science (www.gns.cri.nz/NSHM). In the interim, several major well-instrumented ...

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 analyses the Earthquake Commission’s (EQC) insurance claims database to investigate the influence of seismic intensity and property damage resulting from the Canterbury Earthquake Sequence (CES) on the repair ...

 Previous works have shown that the oblique tectonic convergence between the lithospheric plates of India and Eurasia in NW Himalaya is primarily manifested by the formation of a series of fold- and thrustbelts, and the ...

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, ...

We are embarking on the most significant revision of the NSHM in more than 20 years. An international team of more than 50 scientists is contributing to two working groups: 1) Seismicity Rate Models (SRM); and 2) Ground ...

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 ...
