A video of a presentation by Dr Sarah Beaven during the Social Recovery Stream of the 2016 People in Disasters Conference. The presentation is titled, "Leading and Coordinating Social Recovery: Lessons from a central recovery agency".The abstract for this presentation reads as follows: This presentation provides an overview of the Canterbury Earthquake Recovery Authority's Social Recovery Lessons and Legacy project. This project was commissioned in 2014 and completed in December 2015. It had three main aims: to capture Canterbury Earthquake Recovery Authority's role in social recovery after the Canterbury earthquakes, to identify lessons learned, and to disseminate these lessons to future recovery practitioners. The project scope spanned four Canterbury Earthquake Recovery Authority work programmes: The Residential Red Zone, the Social and Cultural Outcomes, the Housing Programme, and the Community Resilience Programme. Participants included both Canterbury Earthquake Recovery Authority employees, people from within a range of regional and national agencies, and community and public sector organisations who worked with Canterbury Earthquake Recovery Authority over time. The presentation will outline the origin and design of the project, and present some key findings.

The Screw Driving Sounding (SDS) method developed in Japan is a relatively new insitu testing technique to characterise soft shallow sites, typically those required for residential house construction. An SDS machine drills a rod into the ground in several loading steps while the rod is continuously rotated. Several parameters, such as torque, load and speed of penetration, are recorded at every rotation of the rod. The SDS method has been introduced in New Zealand, and the results of its application for characterising local sites are discussed in this study. A total of 164 SDS tests were conducted in Christchurch, Wellington and Auckland to validate/adjust the methodologies originally developed based on the Japanese practice. Most of the tests were conducted at sites where cone penetration tests (CPT), standard penetration tests (SPT) and borehole logs were available; the comparison of SDS results with existing information showed that the SDS method has great potential as an in-situ testing method for classifying the soils. By compiling the SDS data from 3 different cities and comparing them with the borehole logs, a soil classification chart was generated for identifying the soil type based on SDS parameters. Also, a correlation between fines content and SDS parameters was developed and a procedure for estimating angle of internal friction of sand using SDS parameters was investigated. Furthermore, a correlation was made between the tip resistance of the CPT and the SDS data for different percentages of fines content. The relationship between the SPT N value and a SDS parameter was also proposed. This thesis also presents a methodology for identifying the liquefiable layers of soil using SDS data. SDS tests were performed in both liquefied and non-liquefied areas in Christchurch to find a representative parameter and relationship for predicting the liquefaction potential of soil. Plots were drawn of the cyclic shear stress ratios (CSR) induced by the earthquakes and the corresponding energy of penetration during SDS tests. By identifying liquefied or unliquefied layers using three different popular CPT-based methods, boundary lines corresponding to the various probabilities of liquefaction happening were developed for different ranges of fines contents using logistic regression analysis, these could then be used for estimating the liquefaction potential of soil directly from the SDS data. Finally, the drilling process involved in screw driving sounding was simulated using Abaqus software. Analysis results proved that the model successfully captured the drilling process of the SDS machine in sand. In addition, a chart to predict peak friction angles of sandy sites based on measured SDS parameters for various vertical effective stresses was formulated. As a simple, fast and economical test, the SDS method can be a reliable alternative insitu test for soil and site characterisation, especially for residential house construction.
Predictive modelling provides an efficient means to analyse the coastal environment and generate knowledge for long term urban planning. In this study, the numerical models SWAN and XBeach were incorporated into the ESRI ArcGIS interface by means of the BeachMMtool. This was applied to the Greater Christchurch coastal environment to simulate geomorphological evolution through hydrodynamic forcing. Simulations were performed using the recent sea level rise predictions by the Intergovernmental Panel on Climate Change (2013) to determine whether the statutory requirements outlined in the New Zealand Coastal Policy Statement 2010 are consistent with central, regional and district designations. Our results indicate that current land use zoning in Greater Christchurch is not consistent with these predictions. This is because coastal hazard risk has not been thoroughly quantified during the process of installing the Canterbury Earthquake Recovery Authority residential red zone. However, the Christchurch City Council’s flood management area does provide an extent to which managed coastal retreat is a real option. The results of this research suggest that progradation will continue to occur along the Christchurch foreshore due to the net sediment flux retaining an onshore direction and the current hydrodynamic activity not being strong enough to move sediment offshore. However, inundation during periods of storm surge poses a risk to human habitation on low lying areas around the Avon-Heathcote Estuary and the Brooklands lagoon.
A number of field testing techniques, such as standard penetration test (SPT), cone penetration test (CPT), and Swedish weight sounding (SWS), are popularly used for in-situ characterisation. The screw driving sounding (SDS) method, which has been recently developed in Japan, is an improved version of the SWS technique and measures more parameters, including the required torque, load, speed of penetration and rod friction; these provide more robust way of characterising soil stratigraphy. It is a cost-efficient technique which uses a machine-driven and portable device, making it ideal for testing in small-scale and confined areas. Moreover, with a testing depth of up to 10-15m, it is suitable for liquefaction assessment. Thus, the SDS method has great potential as an in-situ testing method for geotechnical site characterisation, especially for residential house construction. In this paper, the results of SDS tests performed at a variety of sites in New Zealand are presented. The soil database was employed to develop a soil classification chart based on SDS-derived parameters. Moreover, using the data obtained following the 2010-2011 Christchurch Earthquake Se-quence, a methodology was established for liquefaction potential evaluation using SDS data. http://www.isc5.com.au/wp-content/uploads/2016/09/1345-2-ORENSE.pdf
In September 2010 and February 2011 the Canterbury region of New Zealand was struck by two powerful earthquakes, registering magnitude 7.1 and 6.3 respectively on the Richter scale. The second earthquake was centred 10 kilometres south-east of the centre of Christchurch (the region’s capital and New Zealand’s third most populous urban area, with approximately 360,000 residents) at a depth of five kilometres. 185 people were killed, making it the second deadliest natural disaster in New Zealand’s history. (66 people were killed in the collapse of one building alone, the six-storey Canterbury Television building.) The earthquake occurred during the lunch hour, increasing the number of people killed on footpaths and in buses and cars by falling debris. In addition to the loss of life, the earthquake caused catastrophic damage to both land and buildings in Christchurch, particularly in the central business district. Many commercial and residential buildings collapsed in the tremors; others were damaged through soil liquefaction and surface flooding. Over 1,000 buildings in the central business district were eventually demolished because of safety concerns, and an estimated 70,000 people had to leave the city after the earthquakes because their homes were uninhabitable. The New Zealand Government declared a state of national emergency, which stayed in force for ten weeks. In 2014 the Government estimated that the rebuild process would cost NZ$40 billion (approximately US$27.3 billion, a cost equivalent to 17% of New Zealand’s annual GDP). Economists now estimate it could take the New Zealand economy between 50 and 100 years to recover. The earthquakes generated tens of thousands of insurance claims, both against private home insurance companies and against the New Zealand Earthquake Commission, a government-owned statutory body which provides primary natural disaster insurance to residential property owners in New Zealand. These ranged from claims for hundreds of millions of dollars concerning the local port and university to much smaller claims in respect of the thousands of residential homes damaged. Many of these insurance claims resulted in civil proceedings, caused by disputes about policy cover, the extent of the damage and the cost and/or methodology of repairs, as well as failures in communication and delays caused by the overwhelming number of claims. Disputes were complicated by the fact that the Earthquake Commission provides primary insurance cover up to a monetary cap, with any additional costs to be met by the property owner’s private insurer. Litigation funders and non-lawyer claims advocates who took a percentage of any insurance proceeds also soon became involved. These two factors increased the number of parties involved in any given claim and introduced further obstacles to resolution. Resolving these disputes both efficiently and fairly was (and remains) central to the rebuild process. This created an unprecedented challenge for the justice system in Christchurch (and New Zealand), exacerbated by the fact that the Christchurch High Court building was itself damaged in the earthquakes, with the Court having to relocate to temporary premises. (The High Court hears civil claims exceeding NZ$200,000 in value (approximately US$140,000) or those involving particularly complex issues. Most of the claims fell into this category.) This paper will examine the response of the Christchurch High Court to this extraordinary situation as a case study in innovative judging practices and from a jurisprudential perspective. In 2011, following the earthquakes, the High Court made a commitment that earthquake-related civil claims would be dealt with as swiftly as the Court's resources permitted. In May 2012, it commenced a special “Earthquake List” to manage these cases. The list (which is ongoing) seeks to streamline the trial process, resolve quickly claims with precedent value or involving acute personal hardship or large numbers of people, facilitate settlement and generally work proactively and innovatively with local lawyers, technical experts and other stakeholders. For example, the Court maintains a public list (in spreadsheet format, available online) with details of all active cases before the Court, listing the parties and their lawyers, summarising the facts and identifying the legal issues raised. It identifies cases in which issues of general importance have been or will be decided, with the expressed purpose being to assist earthquake litigants and those contemplating litigation and to facilitate communication among parties and lawyers. This paper will posit the Earthquake List as an attempt to implement innovative judging techniques to provide efficient yet just legal processes, and which can be examined from a variety of jurisprudential perspectives. One of these is as a case study in the well-established debate about the dialogic relationship between public decisions and private settlement in the rule of law. Drawing on the work of scholars such as Hazel Genn, Owen Fiss, David Luban, Carrie Menkel-Meadow and Judith Resnik, it will explore the tension between the need to develop the law through the doctrine of precedent and the need to resolve civil disputes fairly, affordably and expeditiously. It will also be informed by the presenter’s personal experience of the interplay between reported decisions and private settlement in post-earthquake Christchurch through her work mediating insurance disputes. From a methodological perspective, this research project itself gives rise to issues suitable for discussion at the Law and Society Annual Meeting. These include the challenges in empirical study of judges, working with data collected by the courts and statistical analysis of the legal process in reference to settlement. September 2015 marked the five-year anniversary of the first Christchurch earthquake. There remains widespread dissatisfaction amongst Christchurch residents with the ongoing delays in resolving claims, particularly insurers, and the rebuild process. There will continue to be challenges in Christchurch for years to come, both from as-yet unresolved claims but also because of the possibility of a new wave of claims arising from poor quality repairs. Thus, a final purpose of presenting this paper at the 2016 Meeting is to gain the benefit of other scholarly perspectives and experiences of innovative judging best practice, with a view to strengthening and improving the judicial processes in Christchurch. This Annual Meeting of the Law and Society Association in New Orleans is a particularly appropriate forum for this paper, given the recent ten year anniversary of Hurricane Katrina and the plenary session theme of “Natural and Unnatural Disasters – human crises and law’s response.” The presenter has a personal connection with this theme, as she was a Fulbright scholar from New Zealand at New York University in 2005/2006 and participated in the student volunteer cleanup effort in New Orleans following Katrina. http://www.lawandsociety.org/NewOrleans2016/docs/2016_Program.pdf
A video of a presentation by David Meates, Chief Executive of the Christchurch District Health Board and the West Coast District Health Board, during the first plenary of the 2016 People in Disasters Conference. The presentation is titled, "Local System Perspective".The abstract for this presentation reads as follows: The devastating Canterbury earthquakes of 2010 and 2011 have resulted in challenges for the people of Canterbury and have altered the population's health needs. In the wake of New Zealand's largest natural disaster, the health system needed to respond rapidly to changing needs and damaged infrastructure in the short-term in the context of developing sustainable long-term solutions. Canterbury was undergoing system transformation prior to the quakes, however the horizon of transformation was brought forward post-quake: 'Vision 2020' became the vision for now. Innovation was enabled as people working across the system addressed new constraints such as the loss of 106 acute hospital beds, 635 aged residential care beds, the loss of general practices and pharmacies as well as damaged non-government organisation sector. A number of new integration initiatives (e.g. a shared electronic health record system, community rehabilitation for older people, community falls prevention) and expansion of existing programs (e.g. acute demand management) were focused on supporting people to stay well in their homes and communities. The system working together in an integrated way has resulted in significant reductions in acute health service utilisation in Canterbury. Acute admission rates have not increased and remain significantly below national rates and the number of acute and rehabilitation bed days have fallen since the quakes, with these trends most evident among older people. However, health needs frequently reported in post-disaster literature have created greater pressures on the system. In particular, an escalating number of people facing mental health problems and coping with acute needs of the migrant rebuild population provide new challenges for a workforce also affected by the quakes. The recovery journey for Canterbury is not over.
A video of a presentation by Garry Williams during the fourth plenary of the 2016 People in Disasters Conference. Williams is the Programme Manager of the Ministry of Education's Greater Christchurch Education Renewal Programme. The presentation is titled, "Education Renewal: A section response to the February 2011 Christchurch earthquake".The abstract for this presentation reads as follows: The Canterbury earthquakes caused a disaster recovery situation unparalleled in New Zealand's history. In addition to widespread damage to residential dwellings and destruction of Christchurch's central business district, the earthquakes damaged more than 200 schools from Hurunui in the north, to the Mackenzie District in the east, and Timaru in the south. The impact on education provision was substantial, with the majority of early childhood centres, schools and tertiary providers experiencing damage or subsequent, with the majority of early childhood centres, schools and tertiary providers experiencing damage or subsequent operational issues caused by the ensuing migration of people. Following the February earthquake, over 12,000 students had left the school they had been attending and enrolled elsewhere - often at a school outside the region. Shortened school days and compression of teaching into short periods meant shift-sharing students engaged in the curriculum being delivered in more diverse ways. School principals and staff reported increased fatigue and stress and changes in student behaviours, often related to repeated exposure to and ongoing reminders of the trauma of the earthquakes. While there has been a shift from direct, trauma-related presentations to the indirect effects of psychological adversity and daily life stresses, international experiences tells us that psychological recovery generally lags behind the immediate physical recovery and rebuilding. The Ministries of Health and Education and the Canterbury District Health Board have developed and implemented a joint action plan to address specifically the emerging mental health issues for youth in Canterbury. However, the impact of vulnerable and stressed adults on children's behaviour contributes to the overall impact of ongoing wellbeing issues on the educational outcomes for the community. There is substantial evidence supporting the need to focus on adults' resilience so they can support children and youth. Much of the Ministry's work around supporting children under stress is through supporting the adults responsible for teaching them and leading their schools. The education renewal programme exists to assist education communities to rebuild and look toward renewal. The response to the earthquakes provides a significant opportunity to better meet the needs and aspirations of children and youth people. All the parents want to see their children eager to learn, achieving success, and gaining knowledge and skills that will, in time, enable them to become confident, adaptable, economically independent adults. But this is not always the case, hence our approach to education renewal seeks to address inequities and improve outcome, while prioritising actions that will have a positive impact on learners in greatest need of assistance.
