The 22 February 2011, Mw6.2-6.3 Christchurch earthquake is the most costly to affect New Zealand, causing 181 fatalities and severely damaging thousands of residential commercial buildings, city lifelines infrastructure. This manuscript presents an overview observed geotechnical aspects this as well some completed on-going research investigations. A unique aspect, which particularly emphasized, severity spatial extent liquefaction occurring in native soils. Overall, both was greater than...
On 4 September 2010, a magnitude Mw 7.1 earthquake struck the Canterbury region on South Island of New Zealand. The epicentre was located in Darfield area about 40 km west city Christchurch. Extensive damage inflicted to lifelines and residential houses due widespread liquefaction lateral spreading areas close major streams, rivers wetlands throughout Christchurch Kaiapoi. Unreinforced masonry buildings also suffered extensive region. Despite severe infrastructure houses, fortunately, no...
The 2010–2011 Canterbury earthquake sequence began with the 4 September 2010, M w 7.1 Darfield and includes up to ten events that induced liquefaction. Most notably, widespread liquefaction was by 6.2 Christchurch earthquakes. combination of well-documented response during multiple events, densely recorded ground motions for detailed subsurface characterization provides an unprecedented opportunity add case histories database. This paper presents applies 50 high-quality cone penetration test...
Widespread liquefaction occurred in the end-dumped gravelly fills and hydraulically-placed dredged sandy fill at CentrePort of Wellington as a result 14 November 2016 Mw7.8 Kaikoura earthquake. This resulted substantial global (mass) settlement lateral movement (spreading) towards sea, which adversely affected wharf structures buildings constructed on shallow deep foundations. paper presents key observations from QuakeCoRE-GEER post-earthquake reconnaissance efforts Wellington.

Abstract The 2022 revision of Aotearoa New Zealand National Seismic Hazard Model (NZ NSHM 2022) has involved significant all datasets and model components. In this article, we present a subset many results from the as well an overview governance, scientific, review processes followed by NZ team. calculated hazard increased for most when compared with previous models. models are available online.
ABSTRACT This article summarizes the development of 2023 New Zealand ground-motion database (NZGMDB). A preceding version was formally used as central in characterization modeling for 2022 (NZ) National Seismic Hazard Model (NSHM) revision. The contains ground motions events with a moment magnitude greater than ∼3.0 from years 2000 to end 2022. Several challenges associated NZ earthquake source metadata are explained, including determination location, magnitude, tectonic classification, and...
The 2017 Puebla, Mexico, earthquake event led to significant damage in many buildings Mexico City. In the months following earthquake, civil engineering students conducted detailed building assessments throughout city. They collected information and structural characteristics for 340 City urban area, with an emphasis on Roma Condesa neighborhoods where they assessed 237 buildings. These are of particular interest due availability seismic records captured by nearby recording stations,...
This paper discusses the performance of road bridges during 2010–2011 Canterbury earthquakes and focuses on response in liquefying soils undergoing lateral spreading. A characteristic spreading-induced mechanism for short-span with rigid superstructures is presented explored using four well-documented case studies. series pseudo-static analyses are then used to investigate observed their pile foundations particular. Deformations damage piles evaluated correlated spreading displacements, key...
Abstract Two short‐period seismometers were permanently installed at depths of 26 and 383 m beneath the Eden Park stadium in central Auckland October 2008 incorporated into Volcano Seismic Network 2011. These borehole temporarily augmented by a surface sensor to characterize site response this location. Despite installations, seismic monitoring is challenging urban environment due high anthropogenic noise that superimposes Earth’s signal. We analyze power spectral density continuous records...
The New Zealand Strong Motion Database provides a wealth of new strong motion data for engineering applications. In order to utilise these in ground prediction, characterisation key site parameters at each the ~497 past and present GeoNet stations represented database is required. Here, we compilation complete set metadata database, including four parameters: i) NZS1170.5 subsoil classification, ii) time-averaged shear-wave velocity depth 30 m (Vs30), iii) fundamental period (Tsite) iv) 1000...
Abstract Flood damage assessments provide critical insights on processes controlling building and loss. Here, we present a novel assessment approach to develop an empirical residential database from five flood events in New Zealand. Object‐level data was collected for hazard characteristics, along with relative component sub‐components ratios. A Random Forest Model Spearman's Rank correlation test were applied analyse variable importance monotonic relationships. results reveal inundation...

The Mw7.8 earthquake on 14 November 2016 near Kaikōura, New Zealand had major impacts the country's transport system. Road, rail and port infrastructure was damaged, creating substantial disruption for operators, residents, tourists, business owners across several regions. During response recovery phases, a large amount of information data associated with system generated, managed, analysed, exchanged within between organisations to assist decision making. In this paper, we characterise how...
A time-averaged 30-m-depth shear wave velocity ( V S30 ) map is developed for New Zealand as a weighted combination of geology-based and terrain-based model. Bayesian updating process allows local measurements to control model estimates where data exist uses other parts the world are sparse or nonexistent. Geostatistical interpolation performed on models using constrain in vicinity data. Conventional regression kriging compared with flexible multivariate normal (MVN) approach that arbitrary...
