The title is 'Main faultline to be probed'. The cartoon shows an image of Maori Party MP Hone Harawira with two small firemen on his shoulder squirting water into one ear so that it explodes out of the other. One of the firemen says 'I tell ya now the next quake will be an eight point four!' Context - The problem of criticism of his own party by maverick Maori Party MP Hone Harawira. Harawira says that many Maori believe the party has not been able to be an independent voice because of its government partnership and so Mr Harawira is calling for his party to consider its options at the next election. Mr Harawira said that the problem was exacerbated because when the Maori Party was going into coalition with National, the whole world was going into recession and when this happens their choice (National) is to help the rich guy, help the big business, on the basis that they will stay here and keep their business here and everybody will get a job He said the Maori Party needed to get back to supporting basic social policies to help the poor. There is a reference to the Christchurch earthquake of 4 September 2010 and the many strange ways of trying to predict the earthquakes and aftershocks that Christchurch has been experiencing..

The cartoon is entitled 'seismic upheaval'. Prime Minister John Key and Finance Minister Bill English stand near great seismic cracks in the ground and stare sadly at a huge wallet, 'Bill's boodle', belonging to Bill English. Vast quantities of banknotes spill out of the cash pocket in the wallet which also contains a 'travel card', a 'house card' and an 'expenses card'. The various cards in the wallet refer to expense account embarrassments relating to Bill English. Etched in the ground are the words 'Christchurch quake' and 'South Canterbury Finance'. The cartoon refers to two major events in the Canterbury area in recent times that have incurred huge government costs; these are the collapse of the South Canterbury Finance Company and the earthquake that struck early Saturday morning 4th September. The South Canterbury Finance Company has been taken into receivership by the government which has guaranteed that all 30,000 fortunate high-risk investors will be paid out $1.6b thanks to the taxpayer. Treasury is assuming that the cost of the earthquake will reach $4 billion, including $2 billion worth of estimated damage to private dwellings and their contents, $1 billion of damage to commercial property, and $1 billion worth of damage to public infrastructure.

Cartoons about political and social issues in New Zealand and overseas. The cartoon has the words 'Tsunami Warning cancelled' in the centre. Above are the words 'The end is nigh... insurance running out! No more cover!' Below the word 'cancelled' are the words 'We have reinsurance!' Context - Civil Defence has cancelled a tsunami warning after a 7.8 magnitude earthquake struck off the Kermadec Islands this morning (7 July 2011) The tsunami image is used to illustrate the problems that could arise from lack of insurance in Christchurch. When their policies run out on 30 June Earthquake-hit Christchurch and Waimakariri councils are in danger of having no property insurance because as the CEO of Civic Assurance, which insures most councils, says, 'the company cannot buy reinsurance'. There was also a potential problem for home-owners when AMI Insurance, the largest insurer of homes in Christchurch, was threatening insolvency. However, AMI has announced that it has re-insurance cover for earthquakes and other natural disasters from tomorrow (1 July 2011) for the next year. The Government feared AMI Insurance's directors would wind up the company affecting a huge section of New Zealand's insurance market and derail the reconstruction of Christchurch, official documents confirm. AMI said it had doubled its cover for the year to June 2012 after three large quakes in the year to June 2011. (Stuff 30 June 2011) Quantity: 1 digital cartoon(s).

Governor of the Reserve Bank Allan Bollard holds a spade over his shoulder and a roll of toilet paper in his hand. Text reads 'Reserve Bank governor moves to restore confidence after the quake -' and Bollard says '..past the silver beet, left at the last of the beans and it's right by the caulis!' The little Evans man says 'What a relief!' Context - Two earthquakes and hundreds of aftershocks have hit Christchurch, the first on 4 September 2010 and a second more devastating one on 22 February 2011. Toilets have been a real problem after the earthquakes with thousands of chemical toilets and portaloos being shipped in - some people, however, use the old kiwi method of digging a long-drop in the back garden. The Reserve Bank has made a relatively large 50-point cut in its benchmark interest rate, the Official Cash Rate (from 3% to 2.5 per cent). Critics say that inflation is already running unacceptably high and there is a threat of much higher inflation in a year or two when the rebuilding of Christchurch begins to put pressure on limited resources. The Reserve Bank acknowledged these factors, but it has chosen instead to focus on the immediate impact of the earthquake on the economy and particularly on all-important business and consumer sentiment.

Base isolation is an incredibly effective technology used in seismic regions throughout the world to limit structural damage and maintain building function, even after severe earthquakes. However, it has so far been underutilised in light-frame wood construction due to perceived cost issues and technical problems, such as a susceptibility to movement under strong wind loads. Light-frame wood buildings make up the majority of residential construction in New Zealand and sustained significant damage during the 2010-2011 Canterbury earthquake sequence, yet the design philosophy has remained largely unchanged for years due to proven life-safety performance. Recently however, with the advent of performance based earthquake engineering, there has been a renewed focus on performance factors such as monetary loss that has driven a want for higher performing residential buildings. This research develops a low-cost approach for the base isolation of light-frame wood buildings using a flat-sliding friction base isolation system, which addresses the perceived cost and technical issues, and verifies the seismic performance through physical testing on the shake table at the University of Canterbury. Results demonstrate excellent seismic performance with no structural damage reported despite a large number of high-intensity earthquake simulations. Numerical models are subsequently developed and calibrated to New Zealand light-frame wood building construction approaches using state-of-the-art wood modelling software, Timber3D. The model is used to accurately predict both superstructure drift and acceleration demand parameters of fixed-base testing undertaken after the base isolation testing programme is completed. The model development allows detailed cost analyses to be undertaken within the performance based earthquake engineering framework that highlights the monetary benefits of using base isolation. Cost assessments indicate the base isolation system is only 6.4% more compared to the traditional fixed-base system. Finally, a design procedure is recommended for base isolated light-frame wood buildings that is founded on the displacement based design (DBD) approach used in the United States and New Zealand. Nonlinear analyses are used to verify the DBD method which indicate its suitability.

Rocket Lab's Electron rocket launch today on the Mahia Peninsula has been scrubbed again, sadly. A power fault this time. Kaikoura residents and businesses are celebrating the re-opening of State Highway 1 north following a year of earthquake repairs. The coastal highway link between Picton and Christchurch was badly damaged during the November 2016 quake but will now re-open during the day from 7am. It will close at 8:30 each night so more repairs and assesments can be done. Kaikoura Top Ten Holiday Park co-owner Ed Nolan tells us what this means for his business and others in the town. The Prime Minister Jainda Ardern says the Government's new families package will reduce child poverty in the country by 48 per cent. We ask the panellists whether this is realistic or if there are other, more entrenched imprediments to lowering poverty in New Zealand. The panellists also discuss the state of the books, and discuss if they worry about national debt iincreasing, as the opposition has warned. The Prime Minister says wealthy New Zealanders can opt out of the Government's Winter Energy Payment, which will see those on a benefit, NZ Superannuation or a Veterans Pension get an extra boost due the winter season. Many are doubtful that will happen though. The panellists discuss why some wealthy people have missed out on tax cuts only to be able to reap the reward of this package. We also ask if they suspect this money will be used for heating purposes. The University of Otago has a new degree which brings science and art together, the BaSc. It aims to break down barriers between the two disciplines. Two students are graduating the degree this week. We talk to Eirenie Taua'i who has been studying Pacific Studies and Neuroscience. We aslk her what careers she is considering now and what it was like to study to very different courses. The families of those who died in the CTV building collapse in Christchurch's 2011 earthquake say they will continue to fight for justice. Police announced earlier this month they won't be prosecuting the engineers of the building after a three-year long investigation. The families met with police to ask and why say they aren't convinced all has been done. We ask panellist, barrister Jonathan Krebs, if other charges could and should be laid.

4th September 2010 a 7.1 magnitude earthquake strikes near Christchurch, New Zealand’s second largest city of approximately 370,000 people. This is followed by a 6.3 magnitude quake on 22nd February 2011 and a 6.4 on 13th June. In February 181 people died and a state of national emergency was declared from 23 February to 30th April. Urban Search and Rescue teams with 150 personnel from New Zealand and 429 from overseas worked tirelessly in addition to Army, Police and Fire services. Within the central business district 1,000 buildings (of 4,000) are expected to be demolished. An estimated 10,000 houses require demolition and over 100,000 were damaged. Meanwhile the over 7,000 aftershocks have become part of the “new normal” for us all. During this time how have libraries supported their staff? What changes have been made to services? What are the resourcing opportunities? This presentation will provide a personal view from Lincoln University, Te Whare Wanaka o Aoraki, Library Teaching and Learning. Lincoln is New Zealand's third oldest university having been founded in 1878. Publicly owned and operated it is New Zealand's specialist land-based university. Lincoln is based on the Canterbury Plains, 22 kilometres south of Christchurch. On campus there was mostly minor damage to buildings while in the Library 200,000 volumes were thrown from the shelves. I will focus on the experiences of the Disaster Team and on our experiences with hosting temporarily displaced staff and students from the Christchurch Polytechnic Institute of Technology, Library, Learning & Information Services. Experiences from two other institutions will be highlighted: Christchurch City Libraries, Ngā Kete Wānanga-o-Ōtautahi. Focusing on the Māori Services Team and the Ngā Pounamu Māori and Ngāi Tahu collections. The Central library located within the red zone cordon has been closed since February, the Central library held the Ngā Pounamu Māori and Ngai Tahu collections, the largest Māori collections in the Christchurch public library network. The lack of access to these collections changed the way the Māori Services Team, part of the larger Programmes, Events and Learning Team at Christchurch City Libraries were able to provide services to their community resulting in new innovative outreach programmes and a focus on promotion of online resources. On 19th December the “temporary” new and smaller Central library Peterborough opened. The retrieved Ngā Pounamu Māori and Ngai Tahu collections "Ngā rakau teitei e iwa”, have since been re-housed and are once again available for use by the public. Te Rūnanga o Ngāi Tahu. This organisation, established by the Te Rūnanga o Ngāi Tahu Act 1996, services the statutory rights for the people of Ngāi Tahu descent and ensures that the benefits of their Treaty Claim Settlement are enjoyed by Ngāi Tahu now and in the future. Ngāi Tahu are the indigenous Māori people of the southern islands of New Zealand - Te Waipounamu. The iwi (people) hold the rangatiratanga or tribal authority to over 80 per cent of the South Island. With their headquarters based in the central business they have also had to be relocated to temporary facilities. This included their library/archive collection of print resources, art works and taonga (cultural treasures).

Research on responses to trauma has historically focused on the negative repercussions of a struggle with adversity. However, more recently, researchers have begun to examine posttraumatic growth: the positive psychological change that emerges from the struggle with a potentially traumatic event. Associations have been found between posttraumatic growth and greater peritraumatic distress, greater objective severity of trauma exposure, greater perceived stressfulness of events, social support, female gender, cognitive and behavioural responses to trauma, and personality measures. Posttraumatic growth has been measured typically in individuals with varying levels of posttraumatic stress disorder symptoms and other psychological difficulties, such as depression and anxiety. Although some theory and research posits that higher resilience would prohibit posttraumatic growth, no studies have examined posttraumatic growth in a resilient sample. The Canterbury earthquake sequence of 2010 and 2011 involved potentially traumatic events that saw the community struggle with a variety of challenges. However, in the midst of earthquake destruction, some positive initiatives emerged, driven by locals. The Gap Filler project (using city spaces left empty from fallen buildings for art and interactive community projects) and the Student Volunteer Army (groups of volunteers coordinated to help others in need) are examples of this. In this context, it seemed likely that posttraumatic growth was occurring and might be seen in individuals who were coping well with challenges. Culture is theorised to influence the posttraumatic growth process (Calhoun, Cann, & Tedeschi, 2010), and the nature of the trauma undergone is also likely to influence the process of growth. The current thesis measures posttraumatic growth quantitatively and qualitatively in a New Zealand sample. It measures and describes posttraumatic growth in a resilient population after the earthquake sequence of 2010 and 2011 in Canterbury, New Zealand. Findings are used to test current models of posttraumatic growth for individuals coping well after trauma and to elaborate on mechanisms proposed by models such as the comprehensive model of posttraumatic growth (Calhoun et al., 2010) and the organismic valuing theory of growth through adversity (Joseph & Linley, 2005). Correlates of posttraumatic growth are examined and likely supporting factors of posttraumatic growth are identified for this population. Study 1 used quantitative analysis to explore correlates of posttraumatic growth and found that greater posttraumatic growth related to greater peritraumatic distress, greater perceived stressfulness of earthquake events, greater objective stressfulness of earthquake events, greater difficulty with stressful life events, less satisfaction with social support, and female gender. Findings from Study 1 give important detail about the nature of distress included in the comprehensive model of posttraumatic growth (Calhoun et al., 2010) for this population. Levels of posttraumatic growth were lower than those in North American studies but similar to those in a Chinese study. The current sample, however, showed lower endorsement of Relating to Others than the Chinese study, perhaps because of cultural differences. Study 2 used qualitative analysis to examine the experience of posttraumatic growth in the sample. The theme of ‘a greater sense of community’ was found and adds to the comprehensive model of posttraumatic growth, in that an expression of posttraumatic growth (a greater connection with others) can inform ongoing social processing in the posttraumatic growth process. Having a formal or informal role in earthquake recovery appeared to influence self-concept and reflection; this elaborates on the influence of role on reflection in Calhoun et al.’s model. Findings illustrate possible mechanisms of the organismic valuing process theorised by Joseph and Linley (2005). Implications include the importance of providing opportunities for individuals to take on a role after a crisis, encouraging them to act to respond to difficulties, and encouraging them to meet personal needs for relatedness, competence, and autonomy. Finding positive aspects to a difficult situation, as well as acknowledging adversity, can be supported in future to help individuals process their traumas. As a society, we can help individuals cope with adversity by providing ways they can meet their needs for relatedness, competence, and autonomy. Community groups likely provide opportunities for members to act in ways that meet such needs. This will allow them to effectively act to meet their needs in times of crisis.

The assessment of damage and remaining capacity after an earthquake is an immediate measure to determine whether a reinforced concrete (RC) building is usable and safe for occupants. The recent Christchurch earthquake (22 February 2011) caused a uniquely severe level of structural damage to modern buildings, resulting in extensive damage to the building stock. About 60% of damaged multistorey concrete buildings (3 storeys and up) were demolished after the earthquake, and the cost of reconstruction amounted to 40 billion NZD. The aftermath disclosed issues of great complexities regarding the future of the RC buildings damaged by the earthquakes. This highlighted the importance of post-event decision-making, as the outcome will allow the appropriate course of action—demolition, repair or acceptance of the existing building—to be considered. To adopt the proper strategy, accurate assessment of the residual capacity and the level of damage is required. This doctoral dissertation aims to assess the damage and remaining capacity at constituent material and member level (i.e., concrete material and beams) through a systematic approach in an attempt to address part of an existing gap in the available literature. Since the residual capacity of RC members is not unique and depends on previously applied loading history, post-event residual capacity in this study was assessed in terms of fraction of fatigue life (i.e., the number of cycles required to failure). This research comprises three main parts: (1) residual capacity and damage assessment at material level (i.e., concrete), (2) post-yield bond deterioration and damage assessment at the interface of steel and concrete, and, finally, (3) residual capacity and damage assessment at member level (i.e., RC beam). The first part of this research focused on damage assessment and the remaining capacity of concrete from a material point of view. It aimed to employ appropriate and reliable durability-based testing and image-detection techniques to quantify deterioration in the mechanical properties of concrete on the basis that stress-induced damage occurred in the microstructural system of the concrete material. To this end, in the first phase, a feasibility study was conducted in which a combination of oxygen permeability, electrical resistivity and porosity tests were assessed to determine if they were robust and reliable enough to reveal damage which occurred in the microstructural system of concrete. The results, in terms of change in permeability, electrical resistivity and porosity features of disk samples taken from the middle third of damaged concrete cylinders (200 mm × 100 mm) monotonically pre-loaded to 50%, 70%, 90% and 95% of the ultimate strength (f′c), showed the permeability test is a reliable tool to identify the degree of damage, due to its high sensitivity to the load-induced microcracking. In parallel, to determine the residual capacity, the companion damaged concrete cylinders already loaded to the same level of compressive strength were reloaded up to failure. Comparing the stress–strain relationship of damaged concrete with intact material, it was also found that the strain capacity of the reloaded pre-damaged concrete cylinders decreases while strength remained virtually unchanged. In the second phase of the first part, a fluorescent microscopy technique was used to assess the damage and develop a correlation between material degradation, by virtue of the geometrical features, and damage to the concrete. To account for the effect of confinement and cyclic loading, in the third phase, the residual capacity and damage assessment of unconfined and GFRP confined concrete cylinders subjected to low-cycle fatigue loading, was investigated. Similar to the first phase, permeability testing technique was used to provide an indirect evaluation of fatigue damage. Finally, in the fourth phase of the first part, the suitability of permeability testing technique to assess damage was evaluated for cored concrete taken from three types of RC members: columns, beams and a beam-column joint. In view of the fact that the composite action of an RC member is highly dependent on the bond between reinforcement and surrounding concrete, understanding the deterioration of the bond in the post-yield range of strain in steel was crucial to assess damage at member level. Therefore, in the second phase of this research, a state-of-the- art distributed fibre optic strain sensor system (DFOSSS) system was used to evaluate bond deterioration in a cantilever RC beam subjected to monotonic lateral loading. The technology allowed the continuous capture of strain, every 2.6 mm along the length, in both reinforcing bars and cover concrete. The strain profile provided a basis by which the slip, axial stress and bond stress distributions were then established. In the third part, the study focused on the damage assessment and residual capacity of seven half-scale RC beams subjected to a constant-amplitude cyclic loading protocol. In the first stage, the structural performances of three specimens under constant-amplitude fatigue at 1%, 2% and 4% chord rotation (drift) were examined. In parallel, the number of cycles to failure, degradation in strength, stiffness and energy dissipation were characterized. In the second stage, four RC beams were subjected to loading up to 70% and 90% of their fatigue life, at 2% and 4% drift, and then monotonically pulled up to failure. To determine the residual flexural capacity, the lateral force–displacement results of pre-damaged specimens were compared with an undamaged specimen subjected to only monotonic loading. The study showed significant losses in strength, deformability, stiffness and energy dissipation capacity. A nonlinear finite element analysis (FEA) using concrete damage plasticity (CDP) model was also conducted in ABAQUS to numerically investigate the behaviour of the tested specimen. The results of the FE simulations indicated a reasonable response compared with the behaviour of the test specimen in terms of force–displacement and cracking pattern. During the Christchurch earthquake it was observed that the loading history has a significant influence on structural responses. While in conventional pseudo-static loading protocol, internal forces can be redistributed along the plastic length: there is little chance for structures undergoing high initial loading amplitude to redistribute pertinent stresses. As a result, in the third phase of this part, the effect of high rate of loading on the behaviour of seismically designed RC beams was investigated. Two half-scale cantilever RC beams were subjected to similar constant-amplitude cyclic loading at 2% and 4% drifts, but at a rate of 500 mm/s. Due to the incapability of conventional measuring techniques, a motion-tracking system was employed for data acquisition with the high-speed tests. The effect of rate of loading on the fatigue life of specimens (i.e., the number of cycles required to failure), secant stiffness, failure mode, cracking pattern, beam elongations and bar fracture surface were analysed. Integrating the results of all parts of this research has resulted in a better understanding of residual capacity and the development of damage at both the material and member level by using a low-cycle fatigue approach.
