Former drama teacher and casting director Rosie Belton (right) has a motto she lives by: "When all else fails - cook!" Her new book Wild Blackberries explores her life through food. It's about how food enhances the feeling of celebration, and comforts in times of sadness. Having lived through nearly four years of earthquakes in her hometown of Christchurch, Rosie tells Wallace Chapman about why the kitchen and dining table provided so much solace in such unstable times.
Topics - Emergency services are at the scene of a cliff collapse at the Port of Lyttelton that has damaged fuel storage tanks. Police say evacuations are underway from Brittan Terrace and Cressy Terrace, with people being taken to Lyttelton Main School. Meanwhile - University of Canterbury researchers have confirmed that Christchurch is now experiencing more frequent and severe flooding due to the impact of the earthquakes.
This thesis is a theoretical exploration of ‘remembrance’ and its production in the interactions between people/s and the landscape. This exploration takes place in the broad context of post earthquake Christchurch with a focus on public spaces along the Ōtākaro – Avon river corridor. Memory is universal to human beings, yet memories are subjective and culturally organized and produced - the relationship between memory and place therefore operates at individual and collective levels. Design responses that facilitate opportunities to create new memories, and also acknowledge the remembered past of human – landscape relationships are critical for social cohesion and wellbeing. I draw on insights from a range of theoretical sources, including critical interpretive methodologies, to validate subjective individual and group responses to memory and place. Such approaches also allowed me, as the researcher, considerable freedom to apply memory theory through film to illustrate ways we can re-member ourselves to our landscapes. The Ōtākaro-Avon river provided the site through and in which film strategies for remembrance are explored. Foregrounding differences in Māori and settler cultural orientations to memory and landscape, has highlighted the need for landscape design to consider remembrance - those cognitive and unseen dimensions that intertwine people and place. I argue it is our task to make space for such diverse relationships, and to ensure these stories and memories, embodied in landscape can be read through generations. I do not prescribe methods or strategies; rather I have sought to encourage thinking and debate and to suggest approaches through which the possibilities for remembrance may be enhanced.
Gaylene Preston has been making feature films and documentaries with a distinctive NZ flavour for over 30 years. Her latest venture is an epic six part drama series called Hope and Wire, which she produced and directed. Set in Christchurch in the aftermath of the devastating earthquakes, Hope and Wire is a fictionalised mix of characters - families that fly apart, others that come together - and what happens to a city that loses it's centre in an instant.
Topics - A Christchurch resident says he just wants to get on with his life after his house was flooded for the ninth time since the 2011 earthquake. Fairfax newspapers today feature the story of an elderly gentleman who has been burgled so many times he's afraid to sleep in his own home. In Southland - A 72-year old woman has had her 30-year church membership revoked because she is living in a de facto relationship.
Today (04/09/14) marks the fourth anniversary since the first earthquake rocked the city and greater Christchurch area. That first quake was magnitude 7.1, and luckily there was only one fatality (possible a heart attack). Since then we have had over 14,000 quakes, most very small in magnitude, but well over 500 of magnitude 4 or greater. 5...
The performance of conventionally designed reinforced concrete (RC) structures during the 2011 Christchurch earthquake has demonstrated that there is greater uncertainty in the seismic performance of RC components than previously understood. RC frame and wall structures in the Christchurch central business district were observed to form undesirable cracks patterns in the plastic hinge region while yield penetration either side of cracks, and into development zones, were less than theoretical predictions. The implications of this unexpected behaviour: (i) significantly less available ductility; (ii) less hysteretic energy dissipation; and (iii) the localization of peak reinforcement strains, results in considerable doubt for the residual capacity of RC structures. The significance of these consequences has prompted a review of potential sources of uncertainty in seismic experimentation with the intention to improve the current confidence level for newly designed conventional RC structures. This paper attempts to revisit the principles of RC mechanics, in particular, to consider the influence of loading history, concrete tensile strength, and reinforcement ratio on the performance of ‘real’ RC structures compared to experimental test specimens.
This paper concerns the explicit consideration of near-fault directivity in conventional ground motion prediction models, and its implication for probabilistic seismic hazard analysis (PSHA) in New Zealand. The proposed approach utilises recently developed models by Shahi & Baker (2011), which account for both the 'narrowband' nature of the directivity pulse on spectral ordinates, and the probability of pulse occurrence at the site of interest. Furthermore, in order to correctly consider directivity, distributed seismicity sources are considered as finite-faults, as opposed to their (incorrect) conventional treatment as point-sources. The significance of directivity on hazard analysis results is illustrated for various vibration periods at generic sites located in Christchurch and Otira, two locations whose seismic hazard is comprised of notably different seismic sources. When compared to the PSHA results considering directivity and distributed seismicity as finite faults, it is shown that the NZS1170.5:2004 directivity factor is notably unconservative for all vibration periods in Otira (i.e. high seismic hazard region); and unconservative for Christchurch at short-to-moderate vibration periods ( < 3s); but conservative at long periods ( > 4s).
Between September 4, 2010 and December 23, 2011, a series of earthquakes struck the South Island of New Zealand including the city of Christchurch producing heavy damage. During the strongest shaking, the unreinforced masonry (URM) building stock in Christchurch was subjected to seismic loading equal to approximately 150-200% of code values. Post-earthquake reconnaissance suggested numerous failures of adhesive anchors used for retrofit connection of roof and floor diaphragms to masonry walls. A team of researchers from the Universities of Auckland (NZ) and Minnesota (USA) conducted a field investigation on the performance of new adhesive anchors installed in existing masonry walls. Variables included adhesive type, anchor diameter, embedment length, anchor inclination, and masonry quality. Buildings were selected that had been slated for demolition but which featured exterior walls that had not been damaged. A summary of the deformation response measured during the field tests are presented. AM - Accepted Manuscript
Millions of urban residents around the world in the coming century will experience severe landscape change – including increased frequencies of flooding due to intensifying storm events and impacts from sea level rise. For cities, collisions of environmental change with mismatched cultural systems present a major threat to infrastructure systems that support urban living. Landscape architects who address these issues express a need to realign infrastructure with underlying natural systems, criticizing the lack of social and environmental considerations in engineering works. Our ability to manage both society and the landscapes we live in to better adapt to unpredictable events and landscape changes is essential if we are to sustain the health and safety of our families, neighbourhoods, and wider community networks. When extreme events like earthquakes or flooding occur in developed areas, the feasibility of returning the land to pre-disturbance use can be questioned. In Christchurch for example, a large expanse of land (630 hectares) within the city was severely damaged by the earthquakes and judged too impractical to repair in the short term. The central government now owns the land and is currently in the process of demolishing the mostly residential houses that formed the predominant land use. Furthermore, cascading impacts from the earthquakes have resulted in a general land subsidence of .5m over much of eastern Christchurch, causing disruptive and damaging flooding. Yet, although disasters can cause severe social and environmental distress, they also hold great potential as a catalyst to increasing adaption. But how might landscape architecture be better positioned to respond to the potential for transformation after disaster? This research asks two core questions: what roles can the discipline of landscape architecture play in improving the resilience of communities so they become more able to adapt to change? And what imaginative concepts could be designed for alternative forms of residential development that better empower residents to understand and adapt the infrastructure that supports them? Through design-directed inquiry, the research found landscape architecture theory to be well positioned to contribute to goals of social-ecological systems resilience. The discipline of landscape architecture could become influential in resilience-oriented multi disciplinary collaborations, with our particular strengths lying in six key areas: the integration of ecological and social processes, improving social capital, engaging with temporality, design-led innovation potential, increasing diversity and our ability to work across multiple scales. Furthermore, several innovative ideas were developed, through a site-based design exploration located within the residential red zone, that attempt to challenge conventional modes of urban living – concepts such as time-based land use, understanding roads as urban waterways, and landscape design and management strategies that increase community participation and awareness of the temporality in landscapes.
War and natural disasters share many features including great loss of life, traumatised populations and haunting memories. The Christchurch earthquakes were the third most costly event of 2011 with total costs of up to $NZ30 billion. Many homes, communities, families and an established way of life have gone for ever. The paper comes from the Women’s Voices project that documents women’s narratives of earthquake trauma and loss and examines their profiles of emotional expression associated with coping. For these women in Christchurch, solace is not about talking experiences of suffering but by doing practical things that inform and are shaped by existing personal narratives. As they relayed this common arc, they also entered into national (and gendered) narrative themes of being practical, stoic, independent and resourceful in the face of tragedy and loss and so embody communal aspects of coping with loss and grief particular to the New Zealand even ‘the South Island settler’ identity narrative. These narratives suggest it useful to rethink key concepts that inform our understanding of coping with disaster and loss.
Soil Liquefaction during Recent Large-Scale Earthquakes contains selected papers presented at the New Zealand – Japan Workshop on Soil Liquefaction during Recent Large-Scale Earthquakes (Auckland, New Zealand, 2-3 December 2013). The 2010-2011 Canterbury earthquakes in New Zealand and the 2011 off the Pacific Coast of Tohoku Earthquake in Japan have caused significant damage to many residential houses due to varying degrees of soil liquefaction over a very wide extent of urban areas unseen in past destructive earthquakes. While soil liquefaction occurred in naturally-sedimented soil formations in Christchurch, most of the areas which liquefied in Tokyo Bay area were reclaimed soil and artificial fill deposits, thus providing researchers with a wide range of soil deposits to characterize soil and site response to large-scale earthquake shaking. Although these earthquakes in New Zealand and Japan caused extensive damage to life and property, they also serve as an opportunity to understand better the response of soil and building foundations to such large-scale earthquake shaking. With the wealth of information obtained in the aftermath of both earthquakes, information-sharing and knowledge-exchange are vital in arriving at liquefaction-proof urban areas in both countries. Data regarding the observed damage to residential houses as well as the lessons learnt are essential for the rebuilding efforts in the coming years and in mitigating buildings located in regions with high liquefaction potential. As part of the MBIE-JSPS collaborative research programme, the Geomechanics Group of the University of Auckland and the Geotechnical Engineering Laboratory of the University of Tokyo co-hosted the workshop to bring together researchers to review the findings and observations from recent large-scale earthquakes related to soil liquefaction and discuss possible measures to mitigate future damage. http://librarysearch.auckland.ac.nz/UOA2_A:Combined_Local:uoa_alma21151785130002091

The Christchurch earthquakes brought to an abrupt halt a process of adaptive reuse and gentrification that was underway in the south eastern corner of the central business district. The retail uses that were a key to the success of this area pre-earthquake could be characterised as small, owner operated, quirky, bohemian, chaotic and relatively low rent. This research reports on the progress of a long term, comprehensive case study that follows the progress of these retailers both before and after the earthquakes. Findings include the immediate post-earthquake intentions to resume business in the same location as soon as possible were thwarted by government imposed cordons of the CBD that were only lifted nearly three years later. But, businesses were resilient and generally reinvented themselves quickly in alternative suburban locations where government “rebuild” restrictions were absent. It remains to be seen if this type of retail will ever return to the CBD as government imposed plans and the rents demanded for retail space in new buildings appear to preclude small owner-operated businesses.
To the casual observer, community gardens may look like places where people just come to grow fruit and vegetables. Through digging beneath surface appearances, however, the research literature suggests that there is more to the creation of and participation in community gardens than that which is immediately apparent. The overall aim of this research was to explore and interpret the meaning of community gardens in terms of the sought and experienced well-being of the individuals who participate, and their associated communities. This research was undertaken in the Christchurch/Selwyn district, in the aftermath of the Christchurch earthquakes of 2010-2011. This research utilised the technique of photo-elicitation interviews to study the meanings attributed to community gardening, in the post-earthquake environment. Five gardens were investigated. Results show that a range of meanings, and well-being outcomes are experienced through a combination of physical, educational, aesthetic appreciation, contemplative, creative and social connections within the garden and within the overall context of nature. Significantly, within the post-earthquake environment, the community gardens can offer participants the opportunity to appreciate life and what it means for them.

The abundance of cone penetration test (CPT) data from subsurface explorations in Christchurch and the surrounding areas provides a useful source of information for a characterization of the near surface shear wave velocity ( ) profile for the region. A portion of the investigations were conducted using seismic CPT, enabling the comparison of measured shear wave velocity with CPT data, and subsequently the evaluation of existing CPT- correlations for applicability to Canterbury-specific soils. The existing correlations are shown to be biased, generally over-predicting the observed with depth, thus demonstrating the need for a Canterbury-specific CPT- correlation.

Shapeshifting is a conference organised by AUT featuring local and international guest speakers, academics, and innovators involved in the world of fashion and textiles. The conference is the first of its kind in the world, and its function isn't about discussing ways to build brands and to talk about trends, but a chance to think outside the box; a means to inspire, network and spark discourse. Sonia Sly talks to Christina Cie about the Christchurch Earthquake and its impact on clothing and identity for the community at large, US artist Nick Cave takes his 'body' of work into extraordinary musical and performing heights with 'Sound Suits' and Co-Director Andreas Mikellis discusses the way in which the notion of 'fashion' is changing and the importance of looking to the future.
This presentation discusses recent empirical ground motion modelling efforts in New Zealand. Firstly, the active shallow crustal and subduction interface and slab ground motion prediction equations (GMPEs) which are employed in the 2010 update of the national seismic hazard model (NSHM) are discussed. Other NZ-specific GMPEs developed, but not incorporated in the 2010 update are then discussed, in particular, the active shallow crustal model of Bradley (2010). A brief comparison of the NZ-specific GMPEs with the near-source ground motions recorded in the Canterbury earthquakes is then presented, given that these recordings collectively provide a significant increase in observed strong motions in the NZ catalogue. The ground motion prediction expert elicitation process that was undertaken following the Canterbury earthquakes for active shallow crustal earthquakes is then discussed. Finally, ongoing GMPE-related activities are discussed including: ground motion and metadata database refinement, improved site characterization of strong motion station, and predictions for subduction zone earthquakes.
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.
Media law developments have continued across many areas in the period to mid-2013. In defamation, the New Zealand courts have begun to consider the issue of third party liability for publication on the internet, with cases involving Google searches and comments on a Facebook page. A parliamentary inquiry into a case that restricted parliamentary privilege has recommended a Parliamentary Privilege Act containing a definition of ‘proceedings in Parliament’. A satirical website increased its popularity when it fought off threatened defamation proceedings. In breach of confidence, a government body, the Earthquake Commission, obtained an interim injunction prohibiting publication of information accidentally released that dealt with the repair of earthquake-damaged properties in Christchurch, and a blogger made the information available online in breach of the order.

This paper develops representative ground motion ensembles for several major earthquake scenarios in New Zealand. Cases considered include representative ground motions for the occurrence of Alpine, Hope, and Porters Pass earthquakes in Christchurch, and the occurrence of Wellington, Wairarapa, and Ohariu, fault ruptures in Wellington. Challenges in the development of ground motion ensembles for subduction zone earthquakes are also highlighted. The ground motions are selected based on the generalized conditional intensity measure (GCIM) approach, ensuring that the ground motion ensembles represent both the mean, and distribution of ground motion intensity which such scenarios could impose. These scenario-based ground motion sets can be used to complement ground motions which are often selected in conjunction with probabilistic seismic hazard analysis, in order to understand the performance of structures for the question “what if this fault ruptures?”
The 2010–2011 Canterbury earthquake sequence began with the 4 September 2010, Mw7.1 Darfield earthquake and includes up to ten events that induced liquefaction. Most notably, widespread liquefaction was induced by the Darfield and Mw6.2 Christchurch earthquakes. The combination of well-documented liquefaction response during multiple events, densely recorded ground motions for the events, and detailed subsurface characterization provides an unprecedented opportunity to add well-documented case histories to the liquefaction database. This paper presents and applies 50 high-quality cone penetration test (CPT) liquefaction case histories to evaluate three commonly used, deterministic, CPT-based simplified liquefaction evaluation procedures. While all the procedures predicted the majority of the cases correctly, the procedure proposed by Idriss and Boulanger (2008) results in the lowest error index for the case histories analyzed, thus indicating better predictions of the observed liquefaction response.
During the Christchurch earthquake of February 2011, several midrise reinforced concrete masonry (RCM) buildings showed performance levels that fall in the range of life safety to near collapse. A case study of one of these buildings, a six-story RCM building deemed to have reached the near collapse performance level, is presented in this paper. The RCM walls on the second floor failed due to toe crushing, reducing the building's lateral resistance in the east–west direction. A three-dimensional (3-D) nonlinear dynamic analysis was conducted to simulate the development of the governing failure mechanism. Analysis results showed that the walls that were damaged were subjected to large compression loads during the earthquake, which caused an increase in their in-plane lateral strength but reduced their ductility capacity. After toe crushing failure, axial instability of the model was prevented by a redistribution of gravity loads. VoR - Version of Record
