The operation of telecommunication networks is critical during business as usual times, and becomes most vital in post-disaster scenarios, when the services are most needed for restoring other critical lifelines, due to inherent interdependencies, and for supporting emergency and relief management tasks. In spite of the recognized critical importance, the assessment of the seismic performance for the telecommunication infrastructure appears to be underrepresented in the literature. The FP6 QuakeCoRE project “Performance of the Telecommunication Network during the Canterbury Earthquake Sequence” will provide a critical contribution to bridge this gap. Thanks to an unprecedented collaboration between national and international researchers and highly experienced asset managers from Chorus, data and evidences on the physical and functional performance of the telecommunication network after the Canterbury Earthquakes 2010-2011 have been collected and collated. The data will be processed and interpreted aiming to reveal fragilities and resilience of the telecommunication networks to seismic events

Disasters are often followed by a large-scale stimulus supporting the economy through the built environment, which can last years. During this time, official economic indicators tend to suggest the economy is doing well, but as activity winds down, the sentiment can quickly change. In response to the damaging 2011 earthquakes in Canterbury, New Zealand, the regional economy outpaced national economic growth rates for several years during the rebuild. The repair work on the built environment created years of elevated building activity. However, after the peak of the rebuilding activity, as economic and employment growth retracts below national growth, we are left with the question of how the underlying economy performs during large scale stimulus activity in the built environment. This paper assesses the performance of the underlying economy by quantifying the usual, demand-driven level of building activity at this time. Applying an Input–Output approach and excluding the economic benefit gained from the investment stimulus reveals the performance of the underlying economy. The results reveal a strong growing underlying economy, and while convergence was expected as the stimulus slowed down, the results found that growth had already crossed over for some time. The results reveal that the investment stimulus provides an initial 1.5% to 2% growth buffer from the underlying economy before the growth rates cross over. This supports short-term economic recovery and enables the underlying economy to transition away from a significant rebuild stimulus. Once the growth crosses over, five years after the disaster, economic growth in the underlying economy remains buoyant even if official regional economic data suggest otherwise.

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 the keynote presentation by Sir John Holmes, during the first plenary of the 2016 People in Disasters Conference. Holmes is the former United Nations Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator, the current Director of Ditchley Foundation, and the chair of the Board of the International Rescue Committee in the UK. The presentation is titled, "The Politics of Humanity: Reflections on international aid in disasters".The abstract for this presentation reads as follows: As United Nations Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinate from 2007-2010, Sir John Holmes was heavily involved in the coordination of air provision to countries struck by natural and man-made disasters, raising the necessary funds, and the elaboration of humanitarian policy. The international humanitarian system is fragmented and struggling to cope with rising demands from both conflicts such as that in Syria, and the growing effects of climate change. Sir John will talk about what humanitarian aid can and cannot achieve, the frustrations of getting aid through when access may be difficult or denied, and the need to ensure that assistance encompasses protection of civilians and efforts to get them back on their feet, as well as the delivery of essential short term items such as food, water, medical care and shelter. He will discuss the challenges involved in trying to make the different agencies - UN United Nations, non-government organisations and the International Red Cross/Crescent movement - work together effectively. He will reveal some of the problems in dealing with donor and recipient governments who often have their own political and security agendas, and may be little interested in the necessary neutrality and independence of humanitarian aid. He will illustrate these points by practical examples of political and other dilemmas from aid provision in natural disasters such as Cyclone Nargis in Myanmar in 2009, and the Haiti earthquake of 2010, and in conflict situations such as Darfur, Afghanistan and Sri Lanka in the past, and Syria today. He will also draw conclusions and make recommendations about how humanitarian aid might work better, and why politicians and others need to understand more clearly the impartial space required by humanitarian agencies to operate properly.

The 2010-2011 Canterbury earthquake sequence, and the resulting extensive data sets on damaged buildings that have been collected, provide a unique opportunity to exercise and evaluate previously published seismic performance assessment procedures. This poster provides an overview of the authors’ methodology to perform evaluations with two such assessment procedures, namely the P-58 guidelines and the REDi Rating System. P-58, produced by the Federal Emergency Management Agency (FEMA) in the United States, aims to facilitate risk assessment and decision-making by quantifying earthquake ground shaking, structural demands, component damage and resulting consequences in a logical framework. The REDi framework, developed by the engineering firm ARUP, aids stakeholders in implementing resilience-based earthquake design. Preliminary results from the evaluations are presented. These have the potential to provide insights on the ability of the assessment procedures to predict impacts using “real-world” data. However, further work remains to critically analyse these results and to broaden the scope of buildings studied and of impacts predicted.

A poster created by Empowered Christchurch to advertise their submission to the CERA Draft Transition Recovery Plan on social media.The poster reads, "Submission, CERA Draft Transition Recovery Plan. Seismic Risk. One thing we can learn from the past is that seismic risk in Canterbury has been underestimated before the earthquakes struck. This is confirmed in a report for EQC in 1991 (paper 2005). It is also the conclusion of the Royal Commission in the CTV report. A number of recommendations have been made but not followed. For example, neither the AS/NZS 1170.5 standard nor the New Zealand Geotechnical Society guidelines have been updated. Yet another recovery instrument is the Earthquake Prone Building Act, which is still to be passed by Parliament. As the emergency response part of the recovery is now behind us, we need to ensure sustainability for what lies ahead. We need a city that is driven by the people that live in it, and enabled by a bureaucracy that accepts and mitigates risks, rather than transferring them to the most vulnerable residents."

On 15 August 1868, a great earthquake struck off the coast of the Chile-Peru border generating a tsunami that travelled across the Pacific. Wharekauri-Rekohu-Chatham Islands, located 800 km east of Christchurch, Aotearoa-New Zealand (A-NZ) was one of the worst affected locations in A-NZ. Tsunami waves, including three over 6 metres high, injured and killed people, destroyed buildings and infrastructure, and impacted the environment, economy and communities. While experience of disasters, and advancements in disaster risk reduction systems and technology have all significantly advanced A-NZ’s capacity to be ready for and respond to future earthquakes and tsunami, social memory of this event and other tsunamis during our history has diminished. In 2018, a team of scientists, emergency managers and communication specialists collaborated to organise a memorial event on the Chatham Islands and co-ordinate a multi-agency media campaign to commemorate the 150th anniversary of the 1868 Arica tsunami. The purpose was to raise awareness of the disaster and to encourage preparedness for future tsunami. Press releases and science stories were distributed widely by different media outlets and many attended the memorial event indicating public interest for commemorating historical disasters. We highlight the importance of commemorating disaster anniversaries through memorial events, to raise awareness of historical disasters and increase community preparedness for future events – “lest we forget and let us learn.”

Natural catastrophes are increasing worldwide. They are becoming more frequent but also more severe and impactful on our built environment leading to extensive damage and losses. Earthquake events account for the smallest part of natural events; nevertheless seismic damage led to the most fatalities and significant losses over the period 1981-2016 (Munich Re). Damage prediction is helpful for emergency management and the development of earthquake risk mitigation projects. Recent design efforts focused on the application of performance-based design engineering where damage estimation methodologies use fragility and vulnerability functions. However, the approach does not explicitly specify the essential criteria leading to economic losses. There is thus a need for an improved methodology that finds the critical building elements related to significant losses. The here presented methodology uses data science techniques to identify key building features that contribute to the bulk of losses. It uses empirical data collected on site during earthquake reconnaissance mission to train a machine learning model that can further be used for the estimation of building damage post-earthquake. The first model is developed for Christchurch. Empirical building damage data from the 2010-2011 earthquake events is analysed to find the building features that contributed the most to damage. Once processed, the data is used to train a machine-learning model that can be applied to estimate losses in future earthquake events.

Nowadays the telecommunication systems’ performance has a substantial impact on our lifestyle. Their operationality becomes even more substantial in a post-disaster scenario when these services are used in civil protection and emergency plans, as well as for the restoration of all the other critical infrastructure. Despite the relevance of loss of functionality of telecommunication networks on seismic resilience, studies on their performance assessment are few in the literature. The telecommunication system is a distributed network made up of several components (i.e. ducts, utility holes, cabinets, major and local exchanges). Given that these networks cover a large geographical area, they can be easily subjected to the effects of a seismic event, either the ground shaking itself, or co-seismic events such as liquefaction and landslides. In this paper, an analysis of the data collected after the 2010-2011 Canterbury Earthquake Sequence (CES) and the 2016 Kaikoura Earthquake in New Zealand is conducted. Analysing these data, information gaps are critically identified regarding physical and functional failures of the telecommunication components, the timeline of repair/reconstruction activities and service recovery, geotechnical tests and land planning maps. Indeed, if these missing data were presented, they could aid the assessment of the seismic resilience. Thus, practical improvements in the post-disaster collection from both a network and organisational viewpoints are proposed through consultation of national and international researchers and highly experienced asset managers from Chorus. Finally, an outline of future studies which could guide towards a more resilient seismic performance of the telecommunication network is presented.

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 the keynote presentation by Alexander C. McFarlane during the third plenary of the 2016 People in Disasters Conference. McFarlane is a Professor of Psychiatry at the University of Adelaide and the Heady of the Centre for Traumatic Stress Studies. The presentation is titled, "Holding onto the Lessons Disasters Teach".The abstract for this presentation reads as follows: Disasters are sentinel points in the life of the communities affected. They bring an unusual focus to community mental health. In so doing, they provide unique opportunities for better understanding and caring for communities. However, one of the difficulties in the disaster field is that many of the lessons from previous disasters are frequently lost. If anything, Norris (in 2006) identified that the quality of disaster research had declined over the previous 25 years. What is critical is that a longitudinal perspective is taken of representative cohorts. Equally, the impact of a disaster should always be judged against the background mental health of the communities affected, including emergency service personnel. Understandably, many of those who are particularly distressed in the aftermath of a disaster are people who have previously experienced a psychiatric disorder. It is important that disaster services are framed against knowledge of this background morbidity and have a broad range of expertise to deal with the emerging symptoms. Equally, it is critical that a long-term perspective is considered rather than short-term support that attempts to ameliorate distress. Future improvement of disaster management depends upon sustaining a body of expertise dealing with the consequences of other forms of traumatic stress such as accidents. This expertise can be redirected to co-ordinate and manage the impact of larger scale events when disasters strike communities. This presentation will highlight the relevance of these issues to the disaster planning in a country such as New Zealand that is prone to earthquakes.

This thesis investigates life-safety risk in earthquakes. The first component of the thesis utilises a dataset of earthquake injuries and deaths from recent earthquakes in New Zealand to identify cause, context, and risk factors of injury and death in the 2011 MW6.3 Christchurch earthquake and 2016 MW7.8 Kaikōura earthquake. Results show that nearly all deaths occurred from being hit by structural elements from buildings, while most injuries were caused by falls, strains and being hit by contents or non-structural elements. Statistical analysis of injured cases compared to an uninjured control group found that age, gender, building damage, shaking intensity, and behaviour during shaking were the most significant risk factors for injury during these earthquakes. The second part of the thesis uses the empirical findings from the first section to develop two tools for managing life-safety risk in earthquakes. The first tool is a casualty estimation model for health system and emergency response planning. An existing casualty model used in New Zealand was validated against observed data from the 2011 Christchurch earthquake and found to underestimate moderate and severe injuries by an order of magnitude. The model was then updated to include human behaviour such as protective actions, falls and strain type injuries that are dependent on shaking intensity, as well as injuries and deaths outside buildings. These improvements resulted in a closer fit to observed casualties for the 2011 Christchurch earthquake. The second tool that was developed is a framework to set seismic loading standards for design based on fatality risk targets. The proposed framework extends the risk-targeted hazard method, by moving beyond collapse risk targets, to fatality risk targets for individuals in buildings and societal risk in cities. The framework also includes treatment of epistemic uncertainty in seismic hazard to allow this uncertainty to be used in risk-based decision making. The framework is demonstrated by showing how the current New Zealand loading standards could be revised to achieve uniform life-safety risk across the country and how the introduction of a new loading factor can reduce risk aggregation in cities.

The supply of water following disasters has always been of significant concern to communities. Failure of water systems not only causes difficulties for residents and critical users but may also affect other hard and soft infrastructure and services. The dependency of communities and other infrastructure on the availability of safe and reliable water places even more emphasis on the resilience of water supply systems. This thesis makes two major contributions. First, it proposes a framework for measuring the multifaceted resilience of water systems, focusing on the significance of the characteristics of different communities for the resilience of water supply systems. The proposed framework, known as the CARE framework, consists of eight principal activities: (1) developing a conceptual framework; (2) selecting appropriate indicators; (3) refining the indicators based on data availability; (4) correlation analysis; (5) scaling the indicators; (6) weighting the variables; (7) measuring the indicators; and (8) aggregating the indicators. This framework allows researchers to develop appropriate indicators in each dimension of resilience (i.e., technical, organisational, social, and economic), and enables decision makers to more easily participate in the process and follow the procedure for composite indicator development. Second, it identifies the significant technical, social, organisational and economic factors, and the relevant indicators for measuring these factors. The factors and indicators were gathered through a comprehensive literature review. They were then verified and ranked through a series of interviews with water supply and resilience specialists, social scientists and economists. Vulnerability, redundancy and criticality were identified as the most significant technical factors affecting water supply system robustness, and consequently resilience. These factors were tested for a scenario earthquake of Mw 7.6 in Pukerua Bay in New Zealand. Four social factors and seven indicators were identified in this study. The social factors are individual demands and capacities, individual involvement in the community, violence level in the community, and trust. The indicators are the Giving Index, homicide rate, assault rate, inverse trust in army, inverse trust in police, mean years of school, and perception of crime. These indicators were tested in Chile and New Zealand, which experienced earthquakes in 2010 and 2011 respectively. The social factors were also tested in Vanuatu following TC Pam, which hit the country in March 2015. Interestingly, the organisational dimension contributed the largest number of factors and indicators for measuring water supply resilience to disasters. The study identified six organisational factors and 17 indicators that can affect water supply resilience to disasters. The factors are: disaster precaution; predisaster planning; data availability, data accessibility and information sharing; staff, parts, and equipment availability; pre-disaster maintenance; and governance. The identified factors and their indicators were tested for the case of Christchurch, New Zealand, to understand how organisational capacity affected water supply resilience following the earthquake in February 2011. Governance and availability of critical staff following the earthquake were the strongest organisational factors for the Christchurch City Council, while the lack of early warning systems and emergency response planning were identified as areas that needed to be addressed. Economic capacity and quick access to finance were found to be the main economic factors influencing the resilience of water systems. Quick access to finance is most important in the early stages following a disaster for response and restoration, but its importance declines over time. In contrast, the economic capacity of the disaster struck area and the water sector play a vital role in the subsequent reconstruction phase rather than in the response and restoration period. Indicators for these factors were tested for the case of the February 2011 earthquake in Christchurch, New Zealand. Finally, a new approach to measuring water supply resilience is proposed. This approach measures the resilience of the water supply system based on actual water demand following an earthquake. The demand-based method calculates resilience based on the difference between water demand and system capacity by measuring actual water shortage (i.e., the difference between water availability and demand) following an earthquake.
