Influence of remedial ground densification on seismic site amplification
(New Zealand Society for Earthquake Engineering, 2023-04-19)
While the capability of remedial ground densification techniques to mitigate the adverse effects of liquefaction has been widely investigated in recent decades, the characterization of ground motion amplification in the ...
Simplified approach to rapidly predict road blockages caused by co-seismic landslides
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The 2016 Kaikōura earthquake triggered tens of thousands of landslides leading to several road blockages which isolated the population in Kaikōura and disrupted the transport services across the South Island. The prediction ...
Using 3D geological models to create maps of estimated Vs30 and site period
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The 30-m time-averaged shear-wave velocity (Vs30) and the fundamental site period (T0) are useful parameters for understanding site conditions, informing geotechnical studies as well as infrastructure planning. Unfortunately, ...
Framework Development for a Hybrid Geotechnical-Geospatial Liquefaction Assessment Model
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Liquefaction assessment can be performed using various bodies of knowledge, each with an associated accuracy based on the data involved. Liquefaction assessment models based on directly measured subsurface geotechnical ...
Estimates of site periods from mHVSR analysis of IRIS temporary seismograph networks
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The effects of soil stratigraphy and sedimentary basins on earthquake ground shaking are well-established. These effects can be represented using a range of site metrics, with the focus of this paper being the fundamental ...
