The EQC Minister says she is concerned a threatening letter sent to the Earthquake Commission may have been sent by the same person who sent staff a bullet in the post two years ago. Police are investigating an anonymous threat in a letter sent to EQC staff on the 1st of May. The threat made reference to the Christchurch mosque attacks and has forced EQC to increase security at all its offices. Indira spoke with insurance advocate of 26 years, Dean Lester.

Much of the CBD is still cordoned off and without power (as you should be able to spot) as a result of the damage caused by February's deadly earthquake. This photo clearly shows the extent of the lean that the Hotel Grand Chancellor is now on. Apparently it is out by 1m at the top leaning east. Demolition will start about mid June and is expec...

In the years that have followed the devastating Christchurch earthquake, there have been many stories of the struggles people have faced. Tonight we bring you the tale of the little school in Christchurch's east that took on Wellington's big decision makers and won. Redcliffs School finally reopened last year, after spending the best part of a decade battling for its survival. Our reporter Nick Truebridge and cameraman Nate McKinnon caught up with Redcliffs' principal Rose McInerney to reflect on a tumultuous last 10 years.

Post-tensioned timber technology was originally developed and researched at the University of Canterbury (UC) in New Zealand in 2005. It can provide a low-damage seismic design solution for multi-storey mass timber buildings. Since mass timber products, such as cross-laminated timber (CLT), have high in-plane stiffness, a post-tensioned timber shear wall will deform mainly in a rocking mechanism. The moment capacity of the wall at the base is commonly determined using the elastic form of the Modified Monolithic Beam Analogy (MMBA). In the calculation of the moment capacity at the wall base, it is critical to accurately predict the location of the neutral axis and the timber compressive stress distribution. Three 2/3 scale 8.6m tall post-tensioned CLT walls were experimentally tested under quasi-static cyclic loading – both uni-directional and bi-directional- in this study. These specimens included a single wall, a coupled wall, and a C-shaped core-wall. The main objective was to develop post-tensioned C-shaped timber core-walls for tall timber buildings with enhanced lateral strength and stiffness. To better understand the timber compressive stress distributions at the wall base, particle tracking technology (PTT) technology was applied for the first time to investigate the behaviour of the compression toe. Previous post-tensioned timber testing primarily used the displacement measurements to determine the timber compressive behavior at the wall base or rocking interfaces. However, by using PTT technology, the timber strain measurements in the compression zone can be much more accurate as PTT is able to track the movement of many particles on the timber surface. This paper presents experimental testing results of post-tensioned CLT walls with a focus on capturing timber compressive behavior using PTT. The PTT measurements were able to better capture small base rotations which occurred at the onset of gap opening and capture unexpected phenomena in core-wall tests. The single wall test result herein presented indicates that while the MMBA could predict the moment rotation behavior with reasonable accuracy, the peak strain response was under predicted in the compression toe. Further detailed study is required to better understand the complex strain fields generated reflective of the inherent cross-thickness inhomogeneity and material variability of CLT.

This article argues that active coordination of research engagement after disasters has the potential to maximize research opportunities, improve research quality, increase end-user engagement, and manage escalating research activity to mitigate ethical risks posed to impacted populations. The focus is on the coordination of research activity after the 22nd February 2011 Mw6.2 Christchurch earthquake by the then newly-formed national research consortium, the Natural Hazards Research Platform, which included a social science research moratorium during the declared state of national emergency. Decisions defining this organisation’s functional and structural parameters are analyzed to identify lessons concerning the need for systematic approaches to the management of post disaster research, in collaboration with the response effort. Other lessons include the importance of involving an existing, broadly-based research consortium, ensuring that this consortium's coordination role is fully integrated into emergency management structures, and ensuring that all aspects of decision-making processes are transparent and easily accessed.

This report forms part of a research project examining rural community resilience to natural hazard events, with a particular focus on transient population groups. A preliminary desktop and scoping exercise was undertaken to examine nine communities affected by the Kaikoura earthquake and to identify the variety of transient population groups that are commonly (and increasingly) found in rural New Zealand (see Wilson & Simmons, 2017). From this, four case study communities – Blenheim, Kaikoura, Waiau and St Arnaud – were selected to represent a range of settlement types. These communities varied in respect of social, economic and geographic features, including the presence of particular transient population groups, and earthquake impact. While the 2016 Kaikoura earthquake provided a natural hazard event on which to focus the research, the research interest was in long-term (and broad) community resilience, rather than short-term (and specific) response and recovery actions which occurred post-earthquake.

In this paper Paul Millar outlines the development of the University of Canterbury Quakebox project, a collaborative venture between the UC CEISMIC Canterbury Earthquakes Digital Archive and the New Zealand Institute of Language Brain and Behaviour to preserve people’s earthquake stories for the purposes of research, teaching and commemoration. The project collected over 700 stories on high definition video, and Millar is now looking at using the corpus to underpin a longitudinal study of post-quake experience.

Despite a hasty retreat from its iconic building in Christchurch's Square following the February earthquake, 'The Press', is in celebration mode. It's 150 years since the paper began with a six page edition that sold for six pence. It's first pages warned of the crippling cost of a new tunnel and rail line connecting Lyttelton to Christchurch, and on the back, a for sale ad for 100,000 gorse plants! Deb Nation finds the paper celebrated their centenary 50 years earlier, with memories of pigeon post and paper boys.

Almost half the ACC applications made for mental injuries caused by the Christchurch mosque attacks have been turned down. By the end of April, 85 people had made claims for mental injuries and thirty-five of them had been declined. Decisions are pending on another 25 claims. A woman who suffered post-traumatic stress disorder after the 2011 Christchurch earthquake, and didn't qualify for ACC, says that's tragic. Kirsty Cullen says leaving people who have psychological problems without support from ACC is history repeating. Veronica Schmidt reports.

This is what my lunch looked like after spending a month in my office, post-quake. The banana had liquefied in its skin but there wasn't any mould or anything else. The banana absolutely reeked, though; I ended up tossing everything that had been in the lunch box.

Programme interventions for people who have experienced natural disasters are limited. To investigate whether Group Teen Positive Parenting (GTPPP) programme promoted family functioning in the aftermath of disaster, 14 parents and nine adolescents, self-reported measures of family functioning and adjustment prior to and after the intervention. It was found that GTPPP enhanced parenting competence, parental wellbeing, decreased conflict between parents and their adolescents. These findings suggest that GTPPP may provide a practical way of supporting families after a natural disaster.

During 2010 and 2011, a series of major earthquakes caused widespread damage in the city of Christchurch, New Zealand. The magnitude 6.3 quake in February 2011 caused 185 fatalities. In the ensuing months, the government progressively zoned residential land in Christchurch on the basis of its suitability for future occupation (considering damage from these quakes and future earthquake risk). Over 6,000 homes were placed in the ‘red-zone’, meaning that property owners were forced to sell their land to the Crown. This study analysed patterns of residential mobility amongst thirty-one red-zone households from the suburb of Southshore, Christchurch. Drawing on interviews and surveys, the research traced their experience from the zoning announcement until they had moved to a new residence. The research distinguished between short (before the zoning announcement) and long term (post the red zone ‘deadline’) forms of household relocation. The majority of households in the study were highly resistant to short term movement. Amongst those which did relocate before the zoning decision, the desire to maintain a valued social connection with a person outside of the earthquake environment was often an important factor. Some households also moved out of perceived necessity (e.g. due to lack of power or water). In terms of long-term relocation, concepts of affordability and safety were much more highly valued by the sample when purchasing post-quake property. This resulted in a distinct patterning of post-quake housing location choices. Perceived control over the moving process, relationship with government organisations and insurance companies, and time spent in the red-zone before moving all heavily influenced participants’ disaster experience. Contrary to previous studies, households in this study recorded higher levels of subjective well-being after relocating. The study proposed a typology of movers in the Christchurch post-disaster environment. Four mobility behaviours, or types, are identified: the Committed Stayers (CSs), the Environment Re-Creators (ERCs), the Resigned Acceptors (RAs), and the Opportunistic Movers (OMs). The CSs were defined by their immobility rather than their relocation aspirations, whilst the ERCs attempted to recreate or retain aspects of Southshore through their mobility. The RAs expressed a form of apathy towards the post-quake environment, whereas, on the other hand, the OMs moved relative to pre-earthquake plans, or opportunities that arose from the earthquake itself. Possibilities for further research include examining household adaptability to new residential environments and tracking further mobility patterns in the years following relocation from the red- zone.
