Tsunami have the potential to cause significant disruptions to society, including damage to infrastructure, critical to the every-day operation of society. Effective risk management is required to reduce the potential tsunami impacts to them. Christchurch city, situated on the eastern coast of New Zealand’s South Island, is exposed to a number of far-field tsunami hazards. Although the tsunami hazard has been well identified for Christchurch city infrastructure, the likely impacts have not been well constrained. To support effective risk management a credible and realistic infrastructure impact model is required to inform risk management planning. The objectives of this thesis are to assess the impacts on Christchurch city infrastructure from a credible, hypothetical far-field tsunami scenario. To achieve this an impact assessment process is adopted, using tsunami hazard and exposure measures to determine asset vulnerability and subsequent impacts. However, the thesis identified a number of knowledge gaps in infrastructure vulnerability to tsunami. The thesis addresses this by using two approaches: a tsunami damage matrix; and the development of tsunami fragility functions. The tsunami damage matrix pools together tsunami impacts on infrastructure literature, and post-event field observations. It represents the most comprehensive ‘look-up’ resource for tsunami impacts to infrastructure to date. This damage matrix can inform the assessment of tsunami impacts on Christchurch city infrastructure by providing a measure of damage likelihood at various hazard intensities. A more robust approach to tsunami vulnerability of infrastructure are fragility functions, which are also developed in this thesis. These were based on post-event tsunami surveys of the 2011 ‘Tohoku’ earthquake tsunami in Japan. The fragility functions are limited to road and bridge infrastructure, but represent the highest resolution measure of vulnerability for the given assets. As well as providing a measure of damage likelihood for a given tsunami hazard intensity, these also indicate a level of asset damage. The impact assessment process, and synthesized vulnerability measures, are used to run tsunami impact models for Christchurch infrastructure to determine the probability of asset damage occurring and to determine if impact will reach or exceed a given damage state. The models suggest that infrastructure damage is likely to occur in areas exposed to tsunami inundation in this scenario, with significant damage identified for low elevation roads and bridges. The results are presented and discussed in the context of the risk management framework, with emphasis on using risk assessment to inform risk treatment, monitoring and review. In summary, this thesis A) advances tsunami vulnerability and impact assessment methodologies for infrastructure and B) provides a tsunami impact assessment framework for Christchurch city infrastructure which will inform infrastructure tsunami risk management for planners, emergency managers and lifelines groups.

A video of interviews with four enterprising young Christchurch residents recorded two years after the 22 February 2011 earthquake. The video includes interviews with Gap Filler Director Coralie Winn, Arts Centre Director Andrew Lovatt, artist Mike Hewson, and Student Volunteer Army leader Jason Pembleton. The interviewees are asked four questions: 'What do you think Christchurch city centre will look like in 10 years?', 'What do you most want to see in the new city?', 'What do you miss most about the old city?', and 'What keeps you in Christchurch?'.

Christchurch's plan to have 20,000 people living in the city centre within the next few years looks increasingly set to fail. Official figures from last year show the Central Business District's population hovering at around 7000, stubbornly lower than before the earthquakes struck more than a decade ago. Reporter Anan Zaki has more.

Text reads 'Dan Vettori donates his entire cricket memorabilia to raise money for Christchurch - News'. The cartoon shows Black Caps' captain Dan Vettori carrying large boxes of cricketing equipment and saying 'I'd have donated the entire Black Caps team, but I didn't think they'd raise anything...' Context - Opinion expressed a bit premature and is because of the 3-2 defeat to Pakistan just before the World Cup which meant the Black Caps entered the match as underdogs. However, now New Zealand are brimming with new-found confidence after three wins on the trot took them into the quarter-finals of the World Cup, says opener Brendon McCullum. McCullum said new coach John Wright had been a huge influence behind the scenes. Quantity: 1 digital cartoon(s).

A video of a protest against the demolition of the Majestic Theatre on Manchester Street. The video includes an interview with Christchurch City Councillor Yani Johanson. Johanson talks about how the lack of heritage recovery programme in Christchurch has meant that many heritage buildings have destroyed, mainly through the fast-tracking of consenting by the government. Johanson asks that the government returns normal democratic decision making over heritage to the Christchurch City Council so that the public can have a say. The video also includes footage of the Wizard and a protester speaking outside the Majestic Theatre.

In 2010 Neil Challenger, Head of the School of Landscape Architecture at Lincoln University, stated that the malls surrounding Christchurch drove the life out of the inner city of Christchurch. His economic and sociological concerns were expressed even before the earthquake occurred, and this forms the current hesitation on the rebuilding of Christchurch’s inner city. The position of this research proposal is to establish whether an urban architectural intervention can address these economic and sociological concerns and the potentially devastating effects the suburban mall has had on urban life within Christchurch. The thesis specifically asks whether establishing a mall typology as a landmark building within the inner city can strategically engage the damaged historic buildings of post-earthquake Christchurch in ways that actively preserve these historic remnants. The main intention of this research is to engage the damaged historic buildings of post-earthquake Christchurch in ways that actively preserve these remnants and are also economically viable. By preserving the remnants as active, working elements of the urban fabric, they act as historic reminders or memorials of the event and associated loss, while also actively participating in the regrowth of the city. The thesis argues that contemporary architecture can play a strategic role in these imperatives. Overall this research argues that there exists a distinct requirement for large-scale retail in the inner city urban environment that recognises and responds to the damaged cultural and historic architecture of inner city Christchurch. The objective of the thesis is to propose means to rejuvenate not only the economic vitality of central Christchurch,but also its historic character.

Businesses in the Christchurch suburb of New Brighton say something needs to be done urgently to pull the area out of an economic slump. The seaside town has struggled since the Canterbury Earthquakes, with thousands of people - and customers - leaving the area due to land damage under their homes. And they're pointing the fingers at city leaders like the Christchurch City Council and its rebuild agency, Development Christchurch. Logan Church spoke to New Brighton business owner Nigel Gilmore.

A woman badly injured in the Christchurch earthquake is astonished a new building in the city has been found to have serious seismic flaws. The empty new office building at 230 High Street has multiple problems in its earthquake design that the city council was warned about almost two years ago. Construction of the seven-storey building continued even after those warnings in December 2017. Susie Ferguson speaks to University of Canterbury lecturer Ann Brower, who was crushed after falling masonry fell on her bus during the February twenty-second 2011 earthquake.
The man who documented the aftermath of the Canterbury earthquakes with the film 'When A City Falls' says this week's plan for a new Christchurch CBD will forge a new path for the damaged city.
Council rates in Christchurch city will continue to be calculated using the 2007 house valuations for up to two more years, allowing time for the earthquake's impact on property prices to be assessed.
