Canterbury Earthquakes Symposium - Social Recovery 101 – Waimakariri District Council's social recovery framework and lessons learnt from the Greater Christchurch earthquakes This panel discussion was presented by Sandra James, Director (Connecting People) The Canterbury Earthquakes Symposium, jointly hosted by the Department of the Prime Minister and Cabinet and the Christchurch City Council, was held on 29-30 November 2018 at the University of Canterbury in Christchurch. The purpose of the event was to share lessons from the Canterbury earthquakes so that New Zealand as a whole can be better prepared in future for any similar natural disasters. Speakers and presenters included Greater Christchurch Regeneration Minister, Hon Dr Megan Woods, Christchurch Mayor, Lianne Dalziel, Ngāi Tahu chief executive, Arihia Bennett, head of the public inquiry into EQC, Dame Sylvia Cartwright, urban planner specialising in disaster recovery and castrophe risk management, Dr Laurie Johnson; Christchurch NZ chief executive and former Press editor, Joanna Norris; academic researcher and designer, Barnaby Bennett; and filmmaker, Gerard Smyth. About 300 local and national participants from the public, private, voluntary sectors and academia attended the Symposium. They represented those involved in the Canterbury recovery effort, and also leaders of organisations that may be impacted by future disasters or involved in recovery efforts. The focus of the Symposium was on ensuring that we learn from the Canterbury experience and that we can apply those learnings.

Over 900 buildings in the Christchurch central business district and 10,000 residential homes were demolished following the 22nd of February 2011 Canterbury earthquake, significantly disrupting the rebuild progress. This study looks to quantify the time required for demolitions during this event which will be useful for future earthquake recovery planning. This was done using the Canterbury Earthquake Recovery Authority (CERA) demolition database, which allowed an in-depth look into the duration of each phase of the demolition process. The effect of building location, building height, and the stakeholder which initiated the demolition process (i.e. building owner or CERA) was investigated. The demolition process comprises of five phases; (i) decision making, (ii) procurement and planning, (iii) demolition, (iv) site clean-up, and (v) completion certification. It was found that the time required to decide to demolish the building made up majority of the total demolition duration. Demolition projects initiated by CERA had longer procurement and planning durations, but was quicker in other phases. Demolished buildings in the suburbs had a longer decision making duration, but had little effect on other phases of the demolition process. The decision making and procurement and planning phases of the demolition process were shorter for taller buildings, though the other phases took longer. Fragility functions for the duration of each phase in the demolition process are provided for the various categories of buildings for use in future studies.

It's almost eight years to the day since the first Christchurch earthquake, and as anyone who lives in Christchurch knows, some insurance claims are still in dispute. Dodgy repairs are still being discovered and previously undiscovered damage is being found. Earthquake Commission minister Megan Woods says as problems emerge, people can come back and ask for re-repairs or have their home looked at. But just how much money is in the National Disaster Fund?

Very little research exists on total house seismic performance. This testing programme provides stiffness and response data for five houses of varying ages including contributions of non-structural elements. These light timber framed houses in Christchurch, New Zealand had minor earthquake damage from the 2011 earthquakes and were lateral load tested on site to determine their strength and stiffness, and preliminary damage thresholds. Dynamic characteristics were also investigated. Various loading schemes were utilised including quasi-static loading above the foundation, unidirectional loading through the floor diaphragm, cyclic quasi-static loading and snapback tests. Dynamic analysis on two houses provided the seismic safety levels of post-quake houses with respect to local hazard levels. Compared with New Zealand Building Standards all the tested houses had an excess of strength, damage is a significant consideration in earthquake resilience and was observed in all of the houses. A full size house laboratory test is proposed.

The Christchurch City Council's plans to to help curb a rising homeless population has left some people who live rough worried. The council is considering funding the Christchurch City Mission to employ outreach workers for the first time since the Canterbury earthquakes, and police are increasing central city patrols. Christchurch reporter Logan Church has the story.

We estimate the causal effects of a large unanticipated natural disaster on high schoolers’ university enrolment decisions and subsequent medium-term labour market outcomes. Using national administrative data after a destructive earthquake in New Zealand, we estimate that the disaster raises tertiary education enrolment of recent high school graduates by 6.1 percentage points. The effects are most pronounced for males, students who are academically weak relative to their peers, and students from schools directly damaged by the disaster. As relatively low ability males are overrepresented in sectors of the labour market helped by the earthquake, greater demand for university may stem from permanent changes in deeper behavioural parameters such as risk aversion or time preference, rather than as a coping response to poor economic opportunities.

More than 600 Christchurch home-owners face a wait of up to 18 months before its decided who foots the bill for earthquake repairs that could cost hundreds of millions of dollars. The problem - first revealed on Checkpoint in March - is that owners bought homes thinking all quake damage had been identified and fixed - only to find more problems that weren't addressed. The people affected cannot claim on their insurance - because the damage pre-dates them buying the house - and any grant from the Earthquake Commission is capped. EQC has publicly apologised to those affected but the Minster, Megan Woods, says it's unclear who will pay for the needed repairs.

It could be up to 18 months before 660 Christchurch homeowners know who will pay for earthquake damage repairs with a $1 billion price tag. The bill to fix houses in Christchurch that weren't repaired properly the first time round, or have suffered more damage in aftershocks, is climbing - and the government can't say who's liable. The problem is the homes have new owners who can't claim on theri insurance because the damage pre-dates them owning the home. Earlier Greater Christchurch Regeneration Minister Megan Woods told us the previous National government put no plan in place, and the current government is being left to pick up the pieces. Former Christchurch earthquake recovery minister Gerry Brownlee disputes the issue.

This research examines the connection between accessibility and resilience in post-earthquake Christchurch. This research will provide my community partner with a useful evidence base to help show that increased accessibility does create a more resilient environment. This research uses an in-depth literature review along with qualitative interview approach discussing current levels of accessibility and resilience in Christchurch and whether or not the interview participants believe that increased accessibility in Christchurch will make our city more resilient to future disasters. This research is important because it helps to bridge the connection between accessibility and resilience by showing how accessibility is an important aspect of making a city resilient. In Christchurch specifically, it is a great time to create an accessible and inclusive environment in the post-earthquake rebuild state the city is currently in. Showing that an accessible environment will lead to a more resilient city is important will potentially lead to accessible design being included in the rebuild of places and spaces in Christchurch. In theory, the results of this research show that having an accessible environment leads to universal inclusiveness which in turn, leads to a resilient city. An overarching theme that arose during this research is that accessibility is a means to inclusion and without inclusion a society cannot be resilient. In practice, the results show that for Christchurch to become more accessible and inclusive for people with disabilities, there needs to not only be an increase the accessibility of places and spaces but accessibility to the community as well. Having accessible infrastructure and communities will lead to increased social and urban resilience, especially for individuals with disabilities. This research is beneficial because it helps to bridge the connection between accessibility and resilience. Resilience is important because it help cities prepare for, respond to and recover from disasters and this research helps to show that accessibility is an important part of creating resilience. Some questions still remain unresolved mainly looking into normalising accessibility and deciphering how to prove that accessibility is an issue that effects everybody, not just individuals with disabilities.

This dissertation explores the advocacy for the Christchurch Town Hall that occurred in 2012-2015 after the Canterbury Earthquakes. It frames this advocacy as an instance of collective-action community participation in a heritage decision, and explores the types of heritage values it expressed, particularly social values. The analysis contextualises the advocacy in post-quake Christchurch, and considers its relationship with other developments in local politics, heritage advocacy, and urban activism. In doing so, this dissertation considers how collective action operates as a form of public participation, and the practical implications for understanding and recognising social value.  This research draws on studies of practices that underpin social value recognition in formal heritage management. Social value is held by communities outside institutions. Engaging with communities enables institutions to explore the values of specific places, and to realise the potential of activating local connections with heritage places. Such projects can be seen as participatory practices. However, these processes require skills and resources, and may not be appropriate for all places, communities and institutions. However, literature has understudied collective action as a form of community participation in heritage management. All participation processes have nuances of communities, processes, and context, and this dissertation analyses these in one case. The research specifically asked what heritage values (especially social values) were expressed through collective action, what the relationship was with the participation processes, communities, and wider situation that produced them, and the impact on institutional rhetoric and decisions. The research analysed values expressed in representations made to council in support of the Town Hall. It also used documentary sources and interviews with key informants to analyse the advocacy and decision-making processes and their relationships with the wider context and other grassroots activities. The analysis concluded that the values expressed intertwined social and professional values. They were related to the communities and circumstance that produced them, as an advocacy campaign for a civic heritage building from a Western architectural tradition. The advocacy value arguments were one of several factors that impacted the decision. They have had a lasting impact on rhetoric around the Town Hall, as was a heritage-making practice in its own right. This dissertation makes a number of contributions to the discussion of social value and community in heritage. It suggests connections between advocacy and participation perspectives in heritage. It recommends consideration of nuances of communities, context, and place meanings when using heritage advocacy campaigns as evidence of social value. It adds to the literature on heritage advocacy, and offers a focused analysis of one of many heritage debates that occurred in post-quake Christchurch. Ultimately, it encourages practice to actively integrate social and community values and to develop self-reflexive engagement and valuation processes. Despite inherent challenges, participatory processes offer opportunities to diversify understandings of value, co-produce heritage meanings with communities, and empower citizens in democratic processes around the places they live with and love.

INTRODUCTION This project falls under the Flagship 3: Wellington Coordinated Project. It supports other projects within FP3 to create a holistic understanding of risks posed by collapsed buildings due to future earthquake/s and the secondary consequences of cordoning in the short, mid and long term. Cordoning of the Christchurch CBD for more than two years and its subsequent implications on people and businesses had a significant impact on the recovery of Christchurch. Learning from this and experiences from the Kaikōura earthquake (where cordons were also established around selected buildings, Figure 3) have highlighted the need to understand the effects of cordons and plan for it before an earthquake occurs

Two tragedies have brought two groups of young people from opposite sides of the world together for a special tree planting in Christchurch. Twenty-eight students from Marjory Stoneman Douglas High School in Florida -- the scene of a deadly shooting in February -- are spending the week with the Student Volunteer Army, established after the Christchurch earthquake. Jonathan Mitchell reports.

It's seven years today since Christchurch was rocked by the magnitude 6.3 earthquake. It killed 185 people, injured thousands more and led to whole suburbs and most of the central city being demolished. Seven years on, the rebuild is still underway and some residents are still struggling to get the repairs they want.

Earthquake-triggered soil liquefaction caused extensive damage and heavy economic losses in Christchurch during the 2010-2011 Canterbury earthquakes. The most severe manifestations of liquefaction were associated with the presence of natural deposits of clean sands and silty sands of fluvial origin. However, liquefaction resistance of fines-containing sands is commonly inferred from empirical relationships based on clean sands (i.e. sands with less than 5% fines). Hence, existing evaluation methods have poor accuracy when applied to silty sands. Also, existing methods do not quantify appropriately the influence on liquefaction resistance of soil fabric and structure, which are unique to a specific depositional environment. This study looks at the influence of fines content, soil fabric (i.e. arrangement of soil particles) and structure (e.g. layering, segregation) on the undrained cyclic behaviour and liquefaction resistance of fines-containing sandy soils from Christchurch using Direct Simple Shear (DSS) tests on soil specimens reconstituted in the laboratory with the water sedimentation technique. The poster describes experimental procedures and presents early test results on two sands retrieved at two different sites in Christchurch.

The decision on what to do with Christchurch's earthquake damaged redzone is one step closer, with the end of the public consultation period on the plan for the area. Over the past month Christchurch people have been asked to comment on a draft land use plan for the 602 hectares of land. Now those pitching ideas want the authorities to get on with the next step, so they can have some certainty about whether their projects can go ahead.
