A car on Rowses Road has its entire front half embedded in liquefaction after falling into a sink hole. Behind it, another car has its wheels stuck in the silt. The photographer comments, "Perhaps the most impressively stuck car was this small silver hatchback that went head first into a large hole in a street just off Shortland Street (between Shortland and Breezes Road) in Aranui. The rear hatch was open when we came across it. Apparently there had been one person and a dog inside but they managed to escape. The silt has now settled around and inside the car, making the vehicle an intimidating monument to the earthquake".

A view down Manchester Street, looking south. The road is noticably buckled, and rubble from damaged buildings can be seen beyond the cordon fence. The photographer comments, "Today I ... went for a walk along the cordon to the north of Christchurch CBD which runs about one street back from Bealey Avenue. The soldiers manning the cordon seemed happy for me to take photos but I couldn't see much of the city from the barrier ... what you can see shows there's obviously a lot of damage. The roads are swollen and raised in many place. The once flat CBD will now feature plenty of hills as well as natural traffic calming features".

Members of the University of Canterbury's Digital Media Group in their temporary office in KB02 in Kirkwood Village, the complex of prefabs set up after the earthquakes to provide temporary office and classroom space for the university. The photographer comments, "The e-learning group and the video conferencing team are now located in the Kirkwood Village at the University of Canterbury. It's a very impressive project, about 60 buildings arranged in various configurations with some used for teaching or computer labs, and others as staff offices. We will probably stay here for several years now. Looking across the centre desks to the advisers' area".

The University of Canterbury's E-Learning team's temporary office in the James Hight building. The photographer comments, "First looks at our new temporary (maybe) office space. Our group will stay here until April or May 2011, then will move to another floor in the Central Library. My desk. I hope to get blinds to cover this internal window. Later - blinds are not allowed, so I rotated the desk 180 degrees. My back is now facing the window, but I'm far enough away that people won't be able to read my screens - and I don't have to look at people looking at me".

This poster discusses several possible approaches by which the nonlinear response of surficial soils can be explicitly modelled in physics-based ground motion simulations, focusing on the relative advantages and limitations of the various methodologies. These methods include fully-coupled 3D simulation models that directly allow soil nonlinearity in surficial soils, the domain reduction method for decomposing the physical domain into multiple subdomains for separate simulation, conventional site response analysis uncoupled from the simulations, and finally, the use of simple empirically based site amplification factors We provide the methodology for an ongoing study to explicitly incorporate soil nonlinearity into hybrid broadband simulations of the 2010-2011 Canterbury, New Zealand earthquakes.

Motivation This poster aims to present fragility functions for pipelines buried in liquefaction-prone soils. Existing fragility models used to quantify losses can be based on old data or use complex metrics. Addressing these issues, the proposed functions are based on the Christchurch network and soil and utilizes the Canterbury earthquake sequence (CES) data, partially represented in Figure 1. Figure 1 (a) presents the pipe failure dataset, which describes the date, location and pipe on which failures occurred. Figure 1 (b) shows the simulated ground motion intensity median of the 22nd February 2011 earthquake. To develop the model, the network and soil characteristics have also been utilized.

Background This study examines the performance of site response analysis via nonlinear total-stress 1D wave-propagation for modelling site effects in physics-based ground motion simulations of the 2010-2011 Canterbury, New Zealand earthquake sequence. This approach allows for explicit modeling of 3D ground motion phenomena at the regional scale, as well as detailed nonlinear site effects at the local scale. The approach is compared to a more commonly used empirical VS30 (30 m time-averaged shear wave velocity)-based method for computing site amplification as proposed by Graves and Pitarka (2010, 2015), and to empirical ground motion prediction via a ground motion model (GMM).

A photograph of a sign in the window of a café in Merivale. The sign reads, "To all my very loyal customers, thank you so much for your custom over the past three years. As much as I have enjoyed the previous three years it is time for me to move on especially to spend more time with my two young daughters. On a brighter note, Paul from Chicotis (198 Papanui Road) - I'm sure most of you will already know him - will be taking over very soon and will continue to trade as Chicotis. I wish Paul all the very best and thank you again for your support of Makibo Cafe.

People walk and drive along Manchester Street shortly after the 22 February earthquake. Bricks from collapsed buildings litter the road. The photographer comments, "Just after the aftershock settled on Tuesday afternoon, myself and colleagues fled our Tuam Street office to absolute devastation outside. We couldn't see more than a block in either direction due to the clouds of dust that had arisen from buildings that had just collapsed ... From here, we picked up our vehicles from the CCC car park and headed out to get out of the chaos to a position where we could check on loved ones. Heading first along Manchester Street, buildings that were already heavily damaged were now completely written off".

Army personnel beside the damaged Colombo Street Wesleyan Church. Danger tape has been stretched across Colombo Street to create a cordon. The photographer comments, "After the 22nd February earthquake, my wife and I spent one night in a tent outside our home and then left to stay with friends in Timaru for a couple of nights. On the way along Brougham Street, we passed the Sydenham Church on the corner of Colombo Street and Brougham Street. As you can see from the photos, the upper area has been extensively damaged. Most of the damage appears to be on the east facing wall although we didn't get much of a look at the other sides or, of course, the interior".

A photograph of paper hearts pegged on the cordon fence around the Chinese Methodist Church on Papanui Road. Quotes on the hearts read, "'Even though I walk through the valley of the shadow of death, I will fear no evil for you are with me.' Psalm 23", "'We can do no great things; only small things with great love.' Mother Teresa, and, "'Peace begins with a smile,' Mother Teresa". In the background, the earthquake damage to the Christchurch Chinese Methodist Church can be seen. The wall of the gable has crumbled, the bricks spilling onto the grass below.

The temporary ASB branch in the Re:Start mall. The photographer comments, "The new temporary city mall has been open in Christchurch now for a week. Buildings damaged in the earthquake have been demolished and replaced with cargo containers to create a new, temporary, Cashel Mall. I visited the mall yesterday and was quite impressed with what they have done. The cargo containers have been nicely converted, brightly painted and smartly branded to create some good looking stores ... ASB is the only bank to grab a container, which is fair enough seeing as they appear to be a large sponsor of the mall. The 'Re:START' Cashel Mall signs also display the tag line 'Supported by ASB'".

The level of destruction from the 2011 Christchurch earthquakes led to changes in the New Zealand seismic building code. The destruction showed that the NZ building codes did not fully performed to expectation and needed Improvement to ensure that impact of future earthquakes would be minimised. The building codes have been amended to improve buildings resilience to earthquake and other related extreme loading conditions. Rebuilding Christchurch with the new modifications in the seismic building code comes with its own unique challenges to the entire system. This project investigates the impact of rebuilding Christchurch with the new seismic Building codes in terms of how the new changes affected the building industry and the management of construction.

Dust rises from fallen buildings on Tuam Street shortly after the 22 February earthquake. The photographer comments, "Just after the aftershock settled on Tuesday afternoon, myself and colleagues fled our Tuam Street office to absolute devastation outside. We couldn't see more than a block in either direction due to the clouds of dust that had arisen from buildings that had just collapsed. Above is looking along Tuam Street to the corner of Manchester Street where a number of buildings have just collapsed. This is 1pm and the sky was previously reasonably clear - this is all dust. From here, we picked up our vehicles from the CCC car park and headed out to get out of the chaos to a position where we could check on loved ones".

We present the initial findings from a study of adaptive resilience of lifelines organisations providing essential infrastructure services, in Christchurch, New Zealand following the earthquakes of 2010-2011. Qualitative empirical data was collected from 200 individuals in 11 organisations. Analysis using a grounded theory method identified four major factors that aid organisational response, recovery and renewal following major disruptive events. Our data suggest that quality of top and middle-level leadership, quality of external linkages, level of internal collaboration, ability to learn from experience, and staff well-being and engagement influence adaptive resilience. Our data also suggest that adaptive resilience is a process or capacity, not an outcome and that it is contextual. Post-disaster capacity/resources and post-disaster environment influence the nature of adaptive resilience.

Liquefaction-induced lateral spreading during earthquakes poses a significant hazard to the built environment, as observed in Christchurch during the 2010 to 2011 Canterbury Earthquake Sequence (CES). It is critical that geotechnical earthquake engineers are able to adequately predict both the spatial extent of lateral spreads and magnitudes of associated ground movements for design purposes. Published empirical and semi-empirical models for predicting lateral spread displacements have been shown to vary by a factor of <0.5 to >2 from those measured in parts of Christchurch during CES. Comprehensive post- CES lateral spreading studies have clearly indicated that the spatial distribution of the horizontal displacements and extent of lateral spreading along the Avon River in eastern Christchurch were strongly influenced by geologic, stratigraphic and topographic features.

In 2010 and 2011 a series of earthquakes hit the central region of Canterbury, New Zealand, triggering widespread and damaging liquefaction in the area of Christchurch. Liquefaction occurred in natural clean sand deposits, but also in silty (fines-containing) sand deposits of fluvial origin. Comprehensive research efforts have been subsequently undertaken to identify key factors that influenced liquefaction triggering and severity of its manifestation. This research aims at evaluating the effects of fines content, fabric and layered structure on the cyclic undrained response of silty soils from Christchurch using Direct Simple Shear (DSS) tests. This poster outlines preliminary calibration and verification DSS tests performed on a clean sand to ensure reliability of testing procedures before these are applied to Christchurch soils.

1. INTRODUCTION. Earthquakes and geohazards, such as liquefaction, landslides and rock falls, constitute a major risk for New Zealand communities and can have devastating impacts as the Canterbury 2010/2011 experience shows. Development patterns expose communities to an array of natural hazards, including tsunamis, floods, droughts, and sea level rise amongst others. Fostering community resilience is therefore vitally important. As the rhetoric of resilience is mainstreamed into the statutory framework, a major challenge emerges: how can New Zealand operationalize this complex and sometimes contested concept and build ‘community capitals’? This research seeks to provide insights to this question by critically evaluating how community capitals are conceptualized and how they can contribute to community resilience in the context of the Waimakariri District earthquake recovery and regeneration process.
