Results from a series of 1D seismic effective stress analyses of natural soil deposits from Christchurch are summarized. The analysed soil columns include sites whose performance during the 2010-2011 Canterbury earthquakes varied significantly, from no liquefaction manifestation at the ground surface to very severe liquefaction, in which case a large area of the site was covered by thick soil ejecta. Key soil profile characteristics and response mechanisms affecting the severity of surface liquefaction manifestation and subsequent damage are explored. The influence of shaking intensity on the triggering and contribution of these mechanisms is also discussed. Careful examination of the results highlights the importance of considering the deposit as a whole, i.e. a system of layers, including interactions between layers in the dynamic response and through pore water pressure redistribution and water flow.

Validation is an essential step to assess the applicability of simulated ground motions for utilization in engineering practice, and a comprehensive analysis should include both simple intensity measures (PGA, SA, etc), as well as the seismic response of a range of complex systems obtained by response history analysis. In order to enable a spectrum of complex structural systems to be considered in systematic validation of ground motion simulations in a routine fashion, an automated workflow was developed. Such a workflow enables validation of simulated ground motions in terms of different complex model responses by considering various ground motion sets and different ground motion simulation methods. The automated workflow converts the complex validation process into a routine one by providing a platform to perform the validation process promptly as a built-in process of simulation post-processing. As a case study, validation of simulated ground motions was investigated via the automated workflow by comparing the dynamic responses of three steel special moment frame (SMRF) subjected to the 40 observed and 40 simulated ground motions of 22 February 2011 Christchurch earthquake. The seismic responses of the structures are principally quantified via the peak floor acceleration and maximum inter-storey drift ratio. Overall, the results indicate a general agreement in seismic demands obtained using the recorded and simulated ensembles of ground motions and provide further evidence that simulated ground motions can be used in code-based structural performance assessments in-place of, or in combination with, ensembles of recorded ground motions.

A video of the keynote-presentation by Dr Jeanne LeBlanc, Registered Psychologist, during the second plenary of the 2016 People in Disasters Conference. LeBlanc is a Registered Psychologist, specialising in Clinical Neuropsychology and Rehabilitation. She is the British Columbia Psychological Association (BCPA) Representative for the American Psychological Associate State, Territorial and Provincial Disaster Response Network, and has also been appointed as the Behavioural Health Liaison to the American Board of Disaster Medicine. The presentation is titled, "Machetes and Breadfruit: Medical disaster response challenges in unstable settings".The abstract for this presentation reads as follows: The January 2010 earthquake in Haiti resulted in a massive response to a setting which was already fraught with danger, causing a number of personal, logistical, and safety challenges to responding medical teams. This presentation will provide a first-person account of this experience from the perspective of a behavioural health professional, whose responsibility was both the overall emotional wellbeing of the medical responders, as well as those impacted by the quake. Unique 'lessons learned' by these response teams will be highlighted, and recommendations will be provided for responders considering deploying to future events in highly unstable areas.

Research following the 2010-2011 Canterbury earthquakes investigated the minimum vertical reinforcement required in RC walls to generate well distributed cracking in the plastic hinge region. However, the influence of the loading sequence and rate has not been fully addressed. The new minimum vertical reinforcement limits in NZS 3101:2006 (Amendment 3) include consideration of the material strengths under dynamic load rates, but these provisions have not been validated at a member or system level. A series of tests were conducted on RC prisms to investigate the effect of loading rate and sequence on the local behaviour of RC members. Fifteen axially loaded RC prisms with the designs representing the end region of RC walls were tested under various loading rates to cover the range of pseudo-static and earthquake loading scenarios. These tests will provide substantial data for understanding the local behaviour of RC members, including hysteretic load-deformation behaviour, crack patterns, failure mode, steel strain, strain rate and ductility. Recommendations will be made regarding the effect of loading rate and reinforcement content on the cracking behaviour and ductility of RC members.

In 2010 and 2011 a series of earthquakes hit the central region of Canterbury, New Zealand, triggering widespread and damaging liquefaction in the area of Christchurch. Liquefaction occurred in natural clean sand deposits, but also in silty (fines-containing) sand deposits of fluvial origin. Comprehensive research efforts have been subsequently undertaken to identify key factors that influenced liquefaction triggering and severity of its manifestation. This research aims at evaluating the effects of fines content, fabric and layered structure on the cyclic undrained response of silty soils from Christchurch using Direct Simple Shear (DSS) tests. This poster outlines preliminary calibration and verification DSS tests performed on a clean sand to ensure reliability of testing procedures before these are applied to Christchurch soils.

In response to the February 2011 earthquake, Parliament enacted the Canterbury Earthquake Recovery Act. This emergency legislation provided the executive with extreme powers that extended well beyond the initial emergency response and into the recovery phase. Although New Zealand has the Civil Defence Emergency Management Act 2002, it was unable to cope with the scale and intensity of the Canterbury earthquake sequence. Considering the well-known geological risk facing the Wellington region, this paper will consider whether a standalone “Disaster Recovery Act” should be established to separate an emergency and its response from the recovery phase. Currently, Government policy is to respond reactively to a disaster rather than proactively. In a major event, this typically involves the executive being given the ability to make rules, regulations and policy without the delay or oversight of normal legislative process. In the first part of this paper, I will canvas what a “Disaster Recovery Act” could prescribe and why there is a need to separate recovery from emergency. Secondly, I will consider the shortfalls in the current civil defence recovery framework which necessitates this kind of heavy governmental response after a disaster. In the final section, I will examine how

This research investigates the validation of simulated ground motions on complex structural systems. In this study, the seismic responses of two buildings are compared when they are subjected to as-recorded ground motions and simulated ones. The buildings have been designed based on New Zealand codes and physically constructed in Christchurch, New Zealand. The recorded ground motions are selected from 40 stations database of the historical 22 Feb. 2011 Christchurch earthquake. The Graves and Pitarka (2015) methodology is used to generate the simulated ground motions. The geometric mean of maximum inter-story drift and peak floor acceleration are selected as the main seismic responses. Also, the variation of these parameters due to record to record variability are investigated. Moreover, statistical hypothesis testing is used to investigate the similarity of results between observed and simulated ground motions. The results indicate a general agreement between the peak floor acceleration calculated by simulated and recorded ground motions for two buildings. While according to the hypothesis tests result, the difference in drift can be significant for the building with a shorter period. The results will help engineers and researchers to use or revise the procedure by using simulated ground motions for obtaining seismic responses.

Buildings subject to earthquake shaking will tend to move not only horizontally but also rotate in plan. In-plan rotation is known as “building torsion” and it may occur for a variety of reasons, including stiffness and strength eccentricity and/or torsional effects from ground motions. Methods to consider torsion in structural design standards generally involve analysis of the structure in its elastic state. This is despite the fact that the structural elements can yield, thereby significantly altering the building response and the structural element demands. If demands become too large, the structure may collapse. While a number of studies have been conducted into the behavior of structures considering inelastic building torsion, there appears to be no consensus that one method is better than another and as a result, provisions within current design standards have not adopted recent proposals in the literature. However, the Canterbury Earthquakes Royal Commission recently made the recommendation that provisions to account for inelastic torsional response of buildings be introduced within New Zealand building standards. Consequently, this study examines how and to what extent the torsional response due to system eccentricity may affect the seismic performance of a building and considers what a simple design method should account for. It is concluded that new methods should be simple, be applicable to both the elastic and inelastic range of response, consider bidirectional excitation and include guidance for multi-story systems.

We examined the stratigraphy of alluvial fans formed at the steep range front of the Southern Alps at Te Taho, on the north bank of the Whataroa River in central West Coast, South Island, New Zealand. The range front coincides with the Alpine Fault, an Australian-Pacific plate boundary fault, which produces regular earthquakes. Our study of range front fans revealed aggradation at 100- to 300-year intervals. Radiocarbon ages and soil residence times (SRTs) estimated by a quantitative profile development index allowed us to elucidate the characteristics of four episodes of aggradation since 1000 CE. We postulate a repeating mode of fan behaviour (fan response cycle [FRC]) linked to earthquake cycles via earthquake-triggered landslides. FRCs are characterised by short response time (aggradation followed by incision) and a long phase when channels are entrenched and fan surfaces are stable (persistence time). Currently, the Te Taho and Whataroa River fans are in the latter phase. The four episodes of fan building we determined from an OxCal sequence model correlate to Alpine Fault earthquakes (or other subsidiary events) and support prior landscape evolution studies indicating ≥M7.5 earthquakes as the main driver of episodic sedimentation. Our findings are consistent with other historic non-earthquake events on the West Coast but indicate faster responses than other earthquake sites in New Zealand and elsewhere where rainfall and stream gradients (the basis for stream power) are lower. Judging from the thickness of fan deposits and the short response times, we conclude that pastoral farming (current land-use) on the fans and probably across much of the Whataroa River fan would be impossible for several decades after a major earthquake. The sustainability of regional tourism and agriculture is at risk, more so because of the vulnerability of the single through road in the region (State Highway 6).

A video of a presentation by Thomas Petschner during the Resilience and Response Stream of the 2016 People in Disasters Conference. The presentation is titled, "Medical Clowning in Disaster Zones".The abstract for this presentation reads as follows: To be in a crisis caused by different kinds of natural disasters (as well as a man made incidents), dealing with ongoing increase of problems and frequent confrontation with very bad news isn't something that many people can easily cope with. This applies obviously to affected people but also to the members of SAR teams, doctors in the field and the experienced humanitarians too. The appropriate use of humour in crisis situations and dis-functional environments is a great tool to make those difficult moments more bearable for everyone. It helps injured and traumatised people cope with what they're facing, and can help them to recover more quickly too. At the same time humorous thinking can help to solve some of the complex problems emergency responders face. This is in addition to emergency and medical only reactions - allowing for a more holistic human perspective, which can provide a positive lasting effect. The ability to laugh is hardwired into our systems bringing a huge variety of physical, mental and social benefits. Even a simple smile can cultivate optimism and hope, while laughter can boost a hormone cocktail - which helps to cope with pain, enhance the immune system, reduce stress, re-focus, connect and unite people during difficult times. Humour as an element of psychological response in crisis situations is increasingly understood in a much wider sense: as the human capacity to plan and achieve desired outcomes with less stress, thus resulting in more 'predictable' work in unpredictable situations. So, if we approach certain problems in the same way Medical Clowns do, we may find a more positive solution. Everyone knows that laughter is an essential component of a healthy, happy life. The delivery of 'permission to laugh' into disaster zones makes a big difference to the quality of life for everyone, even if it's for a very short, but important period of time. And it's crucial to get it right as there is no second chance for the first response.

A video of a presentation by Dr Duncan Webb, Partner at Lane Neave, during the third plenary of the 2016 People in Disasters Conference. The presentation is titled, "Loss of Trust and other Earthquake Damage".The abstract for this presentation reads as follows: It was predictable that the earthquakes which hit the Canterbury region in 2010 and 2011 caused trauma. However, it was assumed that recovery would be significantly assisted by governmental agencies and private insurers. The expectation was that these organisations would relieve the financial pressures and associated anxiety caused by damage to property. Some initiatives did exactly that. However, there are many instances where difficulties with insurance and related issues have exacerbated the adverse effects of the earthquakes on people's wellness. In some cases, stresses around property issues have become and independent source of extreme anxiety and have had significant impacts on the quality of people's lives. Underlying this problem is a breakdown in trust between citizen and state, and insurer and insured. This has led to a pervading concern that entitlements are being denied. While such concerns are sometimes well founded, an approach which is premised on mistrust is frequently highly conflicted, costly, and often leads to worse outcomes. Professor Webb will discuss the nature and causes of these difficulties including: the complexity of insurance and repair issues, the organisational ethos of the relevant agencies, the hopes of homeowners and the practical gap which commonly arises between homeowner expectation and agency response. Observations will be offered on how the adverse effects of these issues can be overcome in dealing with claimants, and how such matters can be managed in a way which promotes the wellness of individuals.

This poster discusses several possible approaches by which the nonlinear response of surficial soils can be explicitly modelled in physics-based ground motion simulations, focusing on the relative advantages and limitations of the various methodologies. These methods include fully-coupled 3D simulation models that directly allow soil nonlinearity in surficial soils, the domain reduction method for decomposing the physical domain into multiple subdomains for separate simulation, conventional site response analysis uncoupled from the simulations, and finally, the use of simple empirically based site amplification factors We provide the methodology for an ongoing study to explicitly incorporate soil nonlinearity into hybrid broadband simulations of the 2010-2011 Canterbury, New Zealand earthquakes.

A video of a presentation by Dr Erin Smith during the Community Resilience Stream of the 2016 People in Disasters Conference. The presentation is titled, "A Qualitative Study of Paramedic Duty to Treat During Disaster Response".The abstract for this presentation reads as follows: Disasters place unprecedented demands on emergency medical services and test paramedic personal commitment to the health care profession. Despite this challenge, legal guidelines, professional codes of ethics and ambulance service management guidelines are largely silent on the issue of professional obligations during disasters. They provide little to no guidance on what is expected of paramedics or how they ought to approach their duty to treat in the face of risk. This research explores how paramedics view their duty to treat during disasters. Reasons that may limit or override such a duty are examined. Understanding these issues is important in enabling paramedics to make informed and defensible decisions during disasters. The authors employed qualitative methods to gather Australian paramedic perspectives. Participants' views were analysed and organised according to three emerging themes: the scope of individual paramedic obligations, the role and obligations of ambulance services, and the broader ethical context. Our findings suggest that paramedic decisions around duty to treat will largely depend on their individual perception of risk and competing obligations. A reciprocal obligation is expected of paramedic employers. Ambulance services need to provide their employees with the best current information about risks in order to assist paramedics in making defensible decisions in difficult circumstances. Education plays a key role in providing paramedics with an understanding and appreciation of fundamental professional obligations by focusing attention on both the medical and ethical challenges involved with disaster response. Finally, codes of ethics might be useful, but ultimately paramedic decisions around professional obligations will largely depend on their individual risk assessment, perception of risk, and personal value systems.

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.

A video of a presentation by Matthew Pratt during the Resilience and Response Stream of the 2016 People in Disasters Conference. The presentation is titled, "Investing in Connectedness: Building social capital to save lives and aid recovery".The abstract for this presentation reads as follows: Traditionally experts have developed plans to prepare communities for disasters. This presentation discusses the importance of relationship-building and social capital in building resilient communities that are both 'prepared' to respond to disaster events, and 'enabled' to lead their own recovery. As a member of the Canterbury Earthquake Recovery Authority's Community Resilience Team, I will present the work I undertook to catalyse community recovery. I will draw from case studies of initiatives that have built community connectedness, community capacity, and provided new opportunities for social cohesion and neighbourhood planning. I will compare three case studies that highlight how social capital can aid recovery. Investment in relationships is crucial to aid preparedness and recovery.

Developing a holistic understanding of social, cultural, and economic impacts of disasters can help in building disaster risk knowledge for policy making and planning. Many methods can help in developing an understanding of the impacts of a disaster, including interviews and surveys with people who have experienced disaster, which may be invasive at times and create stress for the participants to relive their experiences. In the past decade, social media, blog posts, video blogs (i.e. “vlogs”), and crowdsourcing mechanisms such as Humanitarian OpenStreetMap and Ushahidi, have become prominent platforms for people to share their experiences and impacts of an event from the ground. These platforms allow for the discovery of a range of impact information, from physical impacts, to social, cultural, and psychological impacts. It can also reveal interesting behavioural information such as their decision to heed a warning or not, as people tend to share their experiences and their reactions online. This information can help researchers and authorities understand both the impacts as well as behavioural responses to hazards, which can then shape how early warning systems are designed and delivered. It can also help to identify gaps in desired behavioural responses. This poster presents a selection of cases identified from the literature and grey literature, such as the Haiti earthquake, the Christchurch earthquake, Hurricane Sandy, and Hurricane Harvey, where online platforms were widely used during and after a disaster to document impacts, experiences, and behavioural responses. A summary of key learnings and areas for future research is provided.

Memorial design in the West has been explored in depth (Stevens and Franck, 2016; Williams, 2007), and for landscape architects it presents opportunities and challenges. However, there is little in the English language literature about memorial design in China. How have Chinese designers responded to the commemorative settings of war and disaster? This study will adopt the method of case study to analyse two of the most representative memorials in China: Nanjing Massacre Memorial Hall (war) and Tangshan Earthquake Memorial Hall (disaster). Both landscapes have undergone three or four renovations and extensions in the last four decades, demonstrating the practical effects of the Chinese landscape theory. These examples of responses to trauma through memorial landscape interventions are testimonies to the witnesses, victims, abusers, ordinary people, youth and the place where the tragedy took place. This study will explore the reconstruction and expansion of the two memorials under the background of China's policies on memorial landscapes in different periods, as well as their functions of each stage. The research will examine how existing Chinese memorial theories exhibit unique responses at different times in response to the sadness and needs experienced by different users. Key Words:memorial landscape; memorial language; victims; descriptive; architecture; experence; disaster; memorial hall; landscape development; Chinese memorial; war.

Disasters are a critical topic for practitioners of landscape architecture. A fundamental role of the profession is disaster prevention or mitigation through practitioners having a thorough understanding of known threats. Once we reach the ‘other side’ of a disaster – the aftermath – landscape architecture plays a central response in dealing with its consequences, rebuilding of settlements and infrastructure and gaining an enhanced understanding of the causes of any failures. Landscape architecture must respond not only to the physical dimensions of disaster landscapes but also to the social, psychological and spiritual aspects. Landscape’s experiential potency is heightened in disasters in ways that may challenge and extend the spectrum of emotions. Identity is rooted in landscape, and massive transformation through the impact of a disaster can lead to ongoing psychological devastation. Memory and landscape are tightly intertwined as part of individual and collective identities, as connections to place and time. The ruptures caused by disasters present a challenge to remembering the lives lost and the prior condition of the landscape, the intimate attachments to places now gone and even the event itself.
