The loss of her home in an earthquake then the loss of her daughter - for New Zealander Linda Collins, one loss shook her physical foundations; the other shook her very being. Told by Denise O'Connell [image:147046:full] [audio_play] [image:151581:half] Linda Collins has a BA in English from Massey University and is a copyeditor on the political desk of The Straits Times in Singapore, where her much-loved daughter, Victoria, took her life four years ago aged 17.  Linda, husband Malcolm McLeod and Victoria were living in Singapore when the 2011 earthquake struck Christchurch, wrecking the house they owned there. Amid insurer and builder delays, the replacement house was only finally completed three years after Victoria’s death.  Linda’s memoir, Loss Adjustment, is her first foray into writing a book, although she is copyeditor of the Lee Kuan Yew international best-seller, Hard Truths to Keep Singapore Going, and used to write for The Expat Files column in Singapore’s Sunday Times.  Earlier this year, she was shortlisted for publisher Hachette’s mentorship programme, based on the submission of her Not Ash chapter from Loss Adjustment. Poetry is a new passion, meanwhile, and she is studying it at La Salle College of the Arts, Singapore. The photo is from her work pass.

This paper explores the responses by a group of children to an art project that was undertaken by a small school in New Zealand after the September 2010 and February 2011 Christchurch earthquakes. Undertaken over a period of two years, the project aimed to find a suitable form of memorialising this significant event in a way that was appropriate and meaningful to the community. Alongside images that related directly to the event of the earthquakes, the art form of a mosaic was chosen, and consisted of images and symbols that clearly drew on the hopes and dreams of a school community who were refusing to be defined by the disaster. The paper 'writes' the mosaic by placing fragments of speech spoken by the children involved in relation to ideas about memory, affect, and the 'sublime', through the work of Jean-Francois Lyotard. The paper explores the mosaic as constituted by the literal and metaphorical 'broken pieces' of the city of Christchurch in ways that confer pedagogic value inscribed through the creation of a public art space by children.

This paper investigates the effects of variability in source rupture parameters on site-specific physics-based simulated ground motions, ascertained through the systematic analysis of ground motion intensity measures. As a preliminary study, we consider simulations of the 22 February 2011 Christchurch earthquake using the Graves and Pitarka (2015) methodology. The effects of source variability are considered via a sensitivity study in which parameters (hypocentre location, earthquake magnitude, average rupture velocity, fault geometry and the Brune stress parameter) are individually varied by one standard deviation. The sensitivity of simulated ground motion intensity measures are subsequently compared against observational data. The preliminary results from this study indicate that uncertainty in the stress parameter and the rupture velocity have the most significant effect on the high frequency amplitudes. Conversely, magnitude uncertainty was found to be most influential on the spectral acceleration amplitudes at low frequencies. Further work is required to extend this preliminary study to exhaustively consider more events and to include parameter covariance. The ultimate results of this research will assist in the validation of the overall simulation method’s accuracy in capturing various rupture parameters, which is essential for the use of simulated ground motion models in probabilistic seismic hazard analysis.

The Christchurch earthquake sequence has been on-going since September 4th 2010. The largest two earthquakes, magnitude (M) 7.1 on September 4th and the M 6.3 on February 22nd 2011 caused immediate and significant damage to the city of Christchurch. As a consequence of the earthquakes, the tourism sector in the Canterbury region has been heavily impacted, with broader impacts being felt throughout the South Island. Resilient Organisations and the University of Canterbury began a series of quantitative investigations into the recovery and response of key business sectors to the earthquakes. The purpose of this study was to build on this work by exploring the outcomes of the earthquakes on the tourism sector, a critical economic driver in the region. Two postal surveys were sent to 719 tourism business managers; the first to businesses in the ‘Impact Zone’ defined as areas that experienced Modified Mercalli intensities greater than 6. The second survey was sent to the remaining businesses throughout the Canterbury region (‘Rest of Canterbury’). Response rates were 46% response for the Impact Zone, and 29% for the Rest of Canterbury. Key findings:

Glazing systems are non-structural elements in a building that, more often than not, appear to be given little consideration in seismic design. Recent experimental work into glazing systems at the University of Canterbury, however, has shown that glazing systems can be very susceptible to serviceability damage, defined as loss of water-tightness. The focus of this paper is to highlight the difference in vulnerability of standard and seismic glazing systems and consider the implications of this for future repair costs and losses. The paper first describes the damage states chosen for glazing units according to the repair strategies required and expected repair costs. This includes three damage states: DS1: Water Leakage, DS2: Gasket Failure and DS3: Frame/Glass Failure. Implementing modern performance-based earthquake engineering, the paper proceeds to highlight a case study comparing costs and expected losses of a standard glazing unit and a seismic glazing unit installed on a case study building. It is shown that the use of seismic glazing units is generally beneficial over time, due to the early onset of serviceability damage in standard glazing units. Finally, the paper provides suggestions for designers aimed at reducing costs related to earthquake induced repairs of glazing.

The cartoon shows three 'Redzone Girls'. The first wears a green tshirt and wears a green 'no restriction' label, the second wears a yellow tshirt and has a yellow 'Limited access' label and the third wears a red tshirt and has a red label that reads 'munted'; she also has a red and white barrier around her. The second and third of the 'girls' are in an increasing state of decrepitude. Behind them is a crumbling brick wall. Context - Christchurch prostitutes aren't letting natural disaster prevent them from plying their trade on the streets despite the dangers of aftershocks in the city. NZPC's Christchurch regional co-ordinator, Anna Reed, said it was a concern sex workers were standing in the shadow of potentially unsafe buildings as the city was shaken by aftershocks, but said the shattered CBD had "left them with no outlet". Christchurch residents are up in arms about the number of prostitutes working in their local neighbourhoods because their usual work areas are out of bounds in the 'red zone'.

Akaroa is a small township situated within Akaroa Harbour, on the southern side of Banks Peninsula. It is approximately 75 kilometres, or 90 minutes by car, from Christchurch City. At the 2006 Census of Population and Dwellings, the ‘usually resident’ population of the township was 510 people. In addition to the usually resident population, Akaroa has a large number of non-resident property owners/ratepayers, many of whom own holiday homes. Many of these holiday homes are available as casual rentals (i.e., they may be occupied by people other than the property owners). The township acts as a service centre for the scattered population of the outer bays area of Akaroa Harbour, many of whom work in Akaroa. Akaroa is a popular day trip or short stay destination for Christchurch residents. Akaroa is also known as a destination which draws upon the French heritage of its pioneer settlers and the associated village charm derived from this heritage. Not unexpectedly, given the size and village character of Akaroa, the increase in cruise ship arrivals and passenger numbers has had an impact upon the town’s community.This research was commissioned and funded by Christchurch and Canterbury Tourism (CCT).

As part of the Canterbury Earthquake Digital Archive, this thesis documents the effects of the earthquakes on the musical life of Christchurch. It concentrates, primarily, on the classical music scene. The thesis examines the difficulties experienced by musical organisations, individual musicians, and teachers as they sought to bring music to the broken city, together with the measures that were necessary in order to overcome those difficulties. It examines how those organisations have worked to re-establish themselves in their particular musical fields. It charts the progress made, to date, along the path to recovery and offers suggestions regarding precautionary measures which, if instituted, could reduce the after-effects of a future disaster. Recognising that not all of the difficulties encountered were directly related to the earthquakes, this thesis also examines the effects on music and musicians, of decision making associated with the recovery effort. The thesis also demonstrates how a destructive event can provide the inspiration for creativity. It recognises the importance of music in maintaining a sense of normality for people, whether they realise it or not, as well as its influences in providing emotional relief in times of stress. Hopefully, it may become a useful guide to which other cities that may be faced with some natural disaster, could refer.

Timber-based hybrid structures provide a prospective solution for utilizing environmentally friendly timber material in the construction of mid-rise or high-rise structures. This study mainly focuses on structural damage evaluation for a type of timber-steel hybrid structures, which incorporate prefabricated light wood frame shear walls into steel moment-resisting frames (SMRFs). The structural damage of such a hybrid structure was evaluated through shake table tests on a four-story large-scale timber-steel hybrid structure. Four ground motion records (i.e., Wenchuan earthquake, Canterbury earthquake, El-Centro earthquake, and Kobe earthquake) were chosen for the tests, with the consideration of three different probability levels (i.e., minor, moderate and major earthquakes) for each record. During the shake table tests, the hybrid structure performed quite well with visual damage only to wood shear walls. No visual damage in SMRF and the frame-to-wall connections was observed. The correlation of visual damage to seismic intensity, modal-based damage index and inter-story drift was discussed. The reported work provided a basis of knowledge for performance-based seismic design (PBSD) for such timber-based hybrid structures.

In this article we utilize grounded theory to explore women’s experiences in the unique construction industry context that followed the 2010 Canterbury (New Zealand) earthquakes. Data were obtained from 36 semi-structured interviews conducted with women working in a variety of occupations in the construction industry. We identify three inter-related categories: capitalizing on opportunity, demonstrating capability and surface tolerance, which together represent a response process that we label ‘deferential tailoring’. The deferential tailoring process explains how women intentionally shape their response to industry conditions through self-regulating behaviors that enables them to successfully seize opportunities and manage gender-related challenges in the working environment. Our findings challenge existing research which suggests that women adopt submissive coping strategies to conform to androcentric norms in the construction industry. Instead, we argue that the process of deferential tailoring can empower women to build positive workplace relationships, enhance career development, and help shift perceptions of the value of their work in the industry.

This paper discusses the seismic performance of the standard RC office building in Christchurch that is given as a structural design example in NZS3101, the concrete structures seismic standard in New Zealand. Firstly the push-over analysis was carried out to evaluate the lateral load carrying capacity of the RC building and then to compare that carrying capacity with the Japanese standard law. The estimated figures showed that the carrying capacity of the New Zealand standard RC office building of NZS3101:2006 was about one third of Japanese demanded carrying capacity. Secondly, time history analysis of the multi-mass system was performed to estimate the maximum response story drift angle using recorded ground motions. Finally, a three-dimensional analysis was carried out to estimate the response of the building to the 22nd February, 2011 Canterbury earthquake. The following outcomes were obtained. 1) The fundamental period of the example RC building is more than twice that of Japanese simplified calculation, 2) The example building’s maximum storey drift angle reached 2.5% under the recorded ground motions. The main purpose of this work is to provide background information of seismic design practice for the reconstruction of Christchurch.

A dramatic consequence of the Christchurch, New Zealand, earthquakes of 2010 and 2011 was the widespread liquefaction in the city. Part of the central business district (CBD) was badly affected by liquefaction but elsewhere large volumes of ejecta were not evident for those parts of the CBD where the upper layers in the soil profile are sandy gravel and gravelly sand. The purpose of the paper is to investigate the effect of the gravel permeability on the rise and dissipation of excess pore water pressure during cyclic loading of a soil profile idealised from Christchurch data. The Cyclic1D software, which performs one-dimensional non-linear effective stress site response analysis, was used. Permeability values associated with gravel were found to suppress the cyclic accumulation of excess pore water pressure in gravel layers. Given that there has not been any systematic measurement of the in situ permeability of the gravels in Christchurch, the modelling in the paper suggests that likely values for the bulk permeability of the gravel layers are within the range suggested in the geotechnical literature. However, the work reported is of wider application than Christchurch and emphasises the controlling influence of permeability on the accumulation and dissipation of cyclic pore pressures.

Maori Party MP for Te Tai Tonga, Rahui Katene' is buried up to her neck in earthquake rubble as she reads a newspaper headline referring to her statement that the aftermath of the earthquake has demonstrated 'racism and ethnic profiling'. Rahui Katene's head is disintegrating and two engineers who are examining the damage decide that 'This can't be repaired, it needs to be condemned'. Rahui Katene says the authorities, who kicked a Christchurch family out of a welfare centre that was set up after the Christchurch earthquake that struck on the 4th September, should apologise for judging them too early and shaming them publicly. Mrs Katene was also concerned about claims that Maori youth were being targeted by police. "I've heard from whanau that in one particular area rangatahi who were volunteering in their community and helping their whanau were accused by police of theft. The whanau are trying to work these issues through with the police, but I'm growing concerned about what appears to be ethnic profiling." Quantity: 1 digital cartoon(s).

The majority of current procedures used to deduce liquefaction potential of soils rely on empirical methods. These methods have been proven to work in the past, but these methods are known to overestimate the liquefaction potential in certain regions of Christchurch due to a whole range of factors, and the theoretical basis behind these methods cannot be explained scientifically. Critical state soil mechanics theory was chosen to provide an explanation for the soil's behaviour during the undrained shearing. Soils from two sites in Christchurch were characterised at regular intervals for the critical layers and tested for the critical state lines (CSL). Various models and relationships were then used to predict the CSL and compared with the actual CSL. However none of the methods used managed to predict the CSL accurately, and a separate Christchurch exclusive relationship was proposed. The resultant state parameter values could be obtained from shear-wave velocity plots and were then developed into cyclic resistance ratios (CRR). These were subsequently compared with cyclic stress ratios (CSR) from recent Christchurch earthquakes to obtain the factor of safety. This CSL-based approach was compared with other empirical methods and was shown to yield a favourable relationship with visual observations at the sites' locations following the earthquake.

Implementing seismic risk mitigation is a major challenge in many earthquake prone regions. The objective of this research is to investigate how property investment market practices can be used to enhance building owners’ decisions to improve seismic performance of earthquake prone buildings (EPBs). A case study method adopted, revealed the impacts of the property market stakeholders’ practices on seismic retrofit decisions. The findings from this research provide significant new insights on how property market-based incentives such as such as mandatory disclosure of seismic risks in all transactions in the property market, effective awareness seismic risk program and a unified earthquake safety assessment information system, can be used to enhance EPBs owners seismic retrofit decisions. These market-based incentives offer compelling reasons for the different property market stakeholders and the public at large to retain, care, invest, and act responsibly to rehabilitate EPBs. The findings suggest need for stakeholders involved in property investment and retrofit decisions to work together to foster seismic rehabilitation of EPBs.

Our poster will present on-going QuakeCoRE-founded work on strong motion seismology for Dunedin-Mosgiel area, focusing on ground motion simulations for Dunedin Central Business District (CBD). Source modelling and ground motion simulations are being carried out using the SCEC (Southern California Earthquakes Center) Broad Band simulation Platform (BBP). The platform computes broadband (0-10 Hz) seismograms for earthquakes and was first implemented at the University of Otago in 2016. As large earthquakes has not been experienced in Dunedin in the time of period of instrumental recording, user-specified scenario simulations are of great value. The Akatore Fault, the most active fault in Otago and closest major fault to Dunedin, is the source focused on in the present study. Simulations for various Akatore Fault source scenarios are run and presented. Path and site effects are key components considered in the simulation process. A 1D shear wave velocity profile is required by SCEC BBP, and this is being generated to represent the Akatore-to-CBD path and site within the BBP. A 3D shear velocity model, with high resolution within Dunedin CBD, is being developed in parallel with this study (see Sangster et al. poster). This model will be the basis for developing a 3D shear wave velocity model for greater Dunedin-Mosgiel area for future ground motion simulations, using Canterbury software (currently under development).

A building boom in the 1980s allowed pre-stressed hollow-core floor construction to be widely adopted in New Zealand, even though the behaviour of these prefabricated elements within buildings was still uncertain. Inspections following the Canterbury and Kaikōura earthquakes has provided evidence of web-splitting, transverse cracking and longitudinal splitting on hollow-core units, confirming the susceptibility of these floors to undesirable failure modes. Hollow-core slabs are mainly designed to resist bending and shear. However, there are many applications in which they are also subjected to torsion. In New Zealand, hollow-core units contain no transverse reinforcement in the soffit concrete below the cells and no web reinforcement. Consequently, their dependable performance in torsion is limited to actions that they can resist before torsional cracking occurs. In previous work by the present authors, a three-dimensional FE modelling approach to study the shear flexural behaviour of precast pre-stressed hollow core units was developed and validated by full-scale experiments. This paper shows how the FE analyses have been extended to investigate the response of HC units subjected to torsional actions. Constitutive models, based on nonlinear fracture mechanics, have been used to numerically predict the torsional capacity of HC units and have been compared with experimental results. The results indicate that the numerical approach is promising and should be developed further as part of future research.

The timeliness and quality of recovery activities are impacted by the organisation and human resourcing of the physical works. This research addresses the suitability of different resourcing strategies on post-disaster demolition and debris management programmes. This qualitative analysis primarily draws on five international case studies including 2010 Canterbury earthquake, 2009 L’Aquila earthquake, 2009 Samoan Tsunami, 2009 Victorian Bushfires and 2005 Hurricane Katrina. The implementation strategies are divided into two categories: collectively and individually facilitated works. The impacts of the implementation strategies chosen are assessed for all disaster waste management activities including demolition, waste collection, transportation, treatment and waste disposal. The impacts assessed include: timeliness, completeness of projects; and environmental, economic and social impacts. Generally, the case studies demonstrate that detritus waste removal and debris from major repair work is managed at an individual property level. Debris collection, demolition and disposal are generally and most effectively carried out as a collective activity. However, implementation strategies are affected by contextual factors (such as funding and legal constraints) and the nature of the disaster waste (degree of hazardous waste, geographical spread of waste etc.) and need to be designed accordingly. Community involvement in recovery activities such as demolition and debris removal is shown to contribute positively to psychosocial recovery.

A video of a presentation by Elizabeth McNaughton during the fourth plenary of the 2016 People in Disasters Conference. McNaughton is the Director of the Canterbury Earthquake Recovery Learning and Legacy programme at the Department of the Prime Minister and Cabinet. The presentation is titled, "Leading in Disaster Recovery: A companion through the chaos".The abstract for this presentation reads as follows: Leading in disaster recovery is a deeply human event - it requires us to reach deep inside of ourselves and bring to others the best of who we can be. It's painful, tiring, rewarding and meaningful. The responsibility can be heavy and at times leaders feel alone. The experienced realities of recovery leadership promoted research involving over 100 people around the globe who have worked in disaster recovery. The result is distilled wisdom from those who have walked in similar shoes to serve as a companion and guide for recovery leaders. The leadership themes in Leading in Disaster Recovery: A companion through the chaos include hard-won, honest, personal, brave insights and practical strategies to serve and support other recovery leaders. This guidance is one attempt amongst many others to change the historic tendency to lurch from disaster to disaster without embedding learning and knowledge - something we cannot afford to do if we are to honour those whose lives have been lost or irreversibly changed by disaster. If we are to honour the courageous efforts of those who have previously served disaster-impacted communities we would be better abled to serve those impacted by future disasters.

The previously unknown Greendale Fault ruptured to the ground surface, causing up to 5 metres horizontal and 1 metre vertical permanent offset of the ground, during the September 2010 Darfield (Canterbury) earthquake. Environment Canterbury commissioned GNS Science, with help from the University of Canterbury, to define a fault avoidance zone and to estimate the fault recurrence interval. There is little evidence for past movement on the fault in the past 16,000 years. However, because of the uncertainties involved, a conservative approach was taken and the fault has been categorised as a Recurrence Interval Class IV fault (a recurrence interval of between 5,000 and 10,000 years). A PhD study by a University of Canterbury student will work towards refining the Recurrence Interval Class over the next three years. Taking a risk-based approach, the Ministry for the Environment Active Fault Guidelines recommend that normal residential development be allowed within the fault avoidance zone for faults of this Recurrence Interval Class, but recommends restrictions for larger community buildings or facilities with post-disaster functions. The report is assisting Selwyn District Council in granting consents for rebuilding houses on or near the Greendale Fault that were damaged by permanent distortion of the ground due to the fault rupture in the September 2010 earthquake. The report provides specific recommendations for building on or close to the Greendale Fault, which are being implemented by Selwyn District Council.

Graffiti on a wooden wall depicts a child pointing at a site across the street and reads "I remember when the Kazbah was over there." The photographer comments, "A local street artist has commemorated Christchurch's deadliest earthquake. The anniversary is tomorrow. Where the photograph was taken was the site of the Ozone Hotel, which has now gone as well. For some of us who live and work in the East of Christchurch the earthquake was not what happened in the City as we were almost unaware of it. We had no water, toilets and most of all no electricity for weeks. For myself petrol was low and with tales of all the petrol stations on our side of town being damaged we could not take the chance of venturing out on severely damaged roads to find no petrol and the possibility of not getting home. We walked around and saw the damage that was local to us. TJ's Kazbah was one that stood out. A building that had a beauty with its round tower standing proud and always looked well kept - it was now collapsed. Its tower, which was once pointing towards the sky was laying on its side. It had kept its shape, but had a lightning shaped crack through it. The one thing that kept us feeling almost normal through the coming weeks was The Press our daily paper still being delivered even though the Press building and staff had suffered so badly themselves.

Refers to the government's earthquake response legislation and the Rugby World Cup 2011 (Empowering) Bill. 26 experts in constitutional law from all six of the country's law faculties have penned a letter condemning the Government's earthquake response legislation. No sooner was their work in the public eye than the similarly flawed Rugby World Cup 2011 (Empowering) Bill was reported back from a select committee, with a recommendation that it pass. It also goes far beyond what is required to get things done. In bypassing the normal consent process, the bill says the authority does not have to hold hearings on applications and that its decisions can be challenged in the High Court only on points of law. Effectively, the legislation asks New Zealanders to accept that the Rugby World Cup Minister knows best. It is he who knows how the event must be run. Precisely the same attitude pervades the Canterbury Earthquake Response and Recovery Act. This hands individual Government ministers the power to change almost every law, thereby handing Parliament's normal law-making role to the Executive. Their decisions cannot be challenged in any court'. (NZ Herald editorial - 1 October 2010) Quantity: 1 digital cartoon(s).

The quality of public space is vital to livable cities. Yet livable cities also require empowered communities. This thesis asks: how is the landscape architect’s design expertise expressed as part of the public participation process, what are the key features of design expertise that lead to an effective design-based participation process and how does quality in the participation process relate to the quality of design outcomes? A theoretical framework is developed from which to clarify the relationship between decision-making processes in design and public participation. Insights from design theory are combined with the findings of key informant interviews with New Zealand and Northern Europe design experts, and with landscape architects, community and Council staff working in post-earthquake Ōtautahi/Christchurch, Aotearoa/New Zealand. Results of a case study of Albion Square in Ōhinehou/Lyttelton reveal that the designer’s interactions with the public play a critical role in shaping elegant design outcomes in public space design. Four key insights reveal that participatory design processes in New Zealand need to be reconsidered in order to enable landscape architects to work more closely with communities in mutual learning, rather than the currently limiting technical problem solving process. Institutional, professional and theoretical implications are drawn from the findings.

The September and February earthquakes were terrifying and devastating. In February, 185 people were killed (this number excludes post earthquake related deaths) and several thousand injured. Damage to infrastructure above and below ground in and around Christchurch was widespread and it will take many years and billions of dollars to rebuild. The ongoing effects of the big quakes and aftershocks are numerous, with the deepest impact being on those who lost family and friends, their livelihoods and homes. What did Cantabrians do during the days, weeks and months of uncertainty and how have we responded? Many grieved, some left, some stayed, some arrived, many shovelled (liquefaction left thousands of tons of silt to be removed from homes and streets), and some used their expertise or knowledge to help in the recovery. This book highlights just some of the projects staff and students from The Faculty of Environment, Society and Design have been involved in from September 2010 to October 2012. The work is ongoing and the plan is to publish another book to document progress and new projects.

A series of earthquakes has forced Christchurch to re-plan and rebuild. Discussions about rebuilding strategies have emphasized the intention of making it a city for the future, sustainable and vibrant. This paper discusses the relationship between microclimate and urban culture in Christchurch based upon the concept of urban comfort. It explores the relationships between environment, people and culture to help understand the local requirements for urban landscape design. In this paper we claim that cultural requirements also should be taken into account when looking for sustainable strategies. A distinctive feature of this research is its focus on the way people are adapting to both surviving prequake and new post‐quake environments. Preliminary findings from the first year of field work using participant observation and 61 in‐depth interviews with Christchurch residents are presented. The interviews were carried out in a variety of urban settings including: established sites (places sustaining relatively little damage) and emerging sites (those requiring rebuilding) during 2011‐2012. Evidence from the interviews highlight future challenges regarding sustainability and urban comfort issues. Post‐quake Christchurch presents a remarkable opportunity to design an urban landscape which provides environmental, economic, social and cultural sustainability. However, to achieve successful outcomes it is fundamental to respond to the local culture. Field data suggest that the strong connections between urban and rural settings present in local culture, lifestyle and landscape generate a particular aesthetic and recreation preference for urban spaces, which should be considered in the urban landscape design strategies.

This report focuses on the Waimakariri District Council's approach to earthquake recovery which was developed as an Integrated, Community-based Recovery Framework. This approach has been held up as exemplary in a number of fora and has received a great deal of interest and support both nationally and internationally. It has evolved as a result of the September earthquake and the thousands of aftershocks that have followed, along with the regulatory changes that have impacted on building safety and land availability since, but it builds on a set of pre-existing competencies and a well-established organisational culture that focusses on: * Working with communities and each other; * Keeping people informed; * Doing better everyday; * Taking responsibility; * Acting with integrity, honesty and trust. The report identifies, and speaks to, three themes or tensions drawn from either the disaster/emergency management literature or actual cases of recovery practice observed here in Canterbury over the last 2 years. These themes are the: 1. unique position of local government to undertake integrated or ‘holistic’ recovery work with community at the centre, versus the lack of clarity around both community and local government’s role in disaster recovery; 2. general consensus that good local government-community relationships are crucial to recovery processes, versus the lack of practical advice on how best to engage, and engage with, communities post-disaster; and 3. balancing Business as Usual (BaU) with recovery issues.Ministry of Civil Defence and Emergency Management.

Recent major earthquakes such as Northridge 1994 and Izmit Kocaeli 1999 highlighted the poor performance of existing buildings constructed prior to the early 1970’s. Low lateral seismic design coefficients and the adopted “working stress design” methodology (essentially an elastic design) lacked any inelastic design considerations, thus leading to inadequate detailing. Insufficient development lengths, lapping within potential plastic hinge regions, lack, or total absence of joint transverse reinforcement, and the use of plain round reinforcement and hooked end anchorages were common throughout the structure. The behaviour is generally dominated by brittle local failure mechanisms (e.g. joint or element shear failures) as well as possible soft-storey mechanisms at a global level. Amongst several possible retrofit interventions, a typical solution is to provide the structure with additional structural walls i.e. external buttressing or column in-fills. Extensive developments on precast, post-tensioned, dissipative systems have shown promise for the use of rocking wall systems to retrofit existing poorly detailed frame structures. In this contribution, the feasibility of such a retrofit intervention is investigated. A displacement-based retrofit procedure is developed and proposed, based on targeting pre-defined performance criteria, such as joint shear and/or column curvature deformation limits. A design example, using the proposed retrofit strategy on a prototype frame is presented. A brief overview on experimental work ongoing at the University of Canterbury investigating the dynamic response of advanced rocking walls for retrofit purposes will be provided.

In recent work on commons and commoning, scholars have argued that we might delink the practice of commoning from property ownership, while paying attention to modes of governance that enable long-term commons to emerge and be sustained. Yet commoning can also occur as a temporary practice, in between and around other forms of use. In this article we reflect on the transitional commoning practices and projects enabled by the Christchurch post-earthquake organisation Life in Vacant Spaces, which emerged to connect and mediate between landowners of vacant inner city demolition sites and temporary creative or entrepreneurial users. While these commons are often framed as transitional or temporary, we argue they have ongoing reverberations changing how people and local government in Christchurch approach common use. Using the cases of the physical space of the Victoria Street site “The Commons” and the virtual space of the Life in Vacant Spaces website, we show how temporary commoning projects can create and sustain the conditions of possibility required for nurturing commoner subjectivities. Thus despite their impermanence, temporary commoning projects provide a useful counter to more dominant forms of urban development and planning premised on property ownership and “permanent” timeframes, in that just as the physical space of the city being opened to commoning possibilities, so too are the expectations and dispositions of the city’s inhabitants, planners, and developers.

The purpose of this research is to investigate men’s experiences of the 2016 7.8 magnitude Kaikōura earthquake and Tsunami. While, research into the impacts of the earthquake has been conducted, few studies have examined how gender shaped people’s experiences of this natural hazard event. Analysing disasters through a gender lens has significantly contributed to disaster scholarship in identifying the resilience and vulnerabilities of individuals and communities pre- and post-disaster (Fordham, 2012; Bradshaw, 2013). This research employs understandings of masculinities (Connell, 2005), to examine men’s strengths and challenges in responding, recovering, and coping following the earthquake. Qualitative inquiry was carried out in Northern Canterbury and Marlborough involving 18 face-to-face interviews with men who were impacted by the Kaikōura earthquake and its aftermath. Interview material is being analysed using thematic and narrative analysis. Some of the preliminary findings have shown that men took on voluntary roles in addition to their fulltime paid work resulting in long hours, poor sleep and little time spent with family. Some men assisted wives and children to high ground then drove into the tsunami zone to check on relatives or to help evacuate people. Although analysis of the findings is currently ongoing, preliminary findings have identified that the men who participated in the study have been negatively impacted by the 2016 Kaikōura earthquake. A theme identified amongst participants was an avoidance to seek support with the challenges they were experiencing due to the earthquake. The research findings align with key characteristics of masculinity, including demonstrating risky behaviours and neglecting self or professional care. This study suggests that these behaviours affect men’s overall resilience, and thus the resilience of the wider community.
