Orana Wildlife Park 'lodge' sleeps passengers from Christchurch airport with no accommodation and who would otherwise sleep at the terminal. The Park staff think that 'they get free accommodation and we have a new paying exhibit!' They have also put up a notice: 'Cheapskates - Do not feed'. Is this a solution to airport 'night kippers'? The shortage of accommodation in Christchurch due to earthquake damage led many air travellers to sleep overnight at the air terminal. Quantity: 1 digital cartoon(s).

Shows a sick and damaged Christchurch Anglican Cathedral in a hospital bed with two attendants. The Cathedral asks 'Can ya just pull the plug and let me die peacefully?'. Context refers to recent comments by Bishop Victoria Matthews that the Christchurch Cathedral is 'being left to die with no dignity' because of ongoing legal battles about its future. There has been ongoing debate and controversy over whether the Cathedral should be demolished, reconstructed or restored following damage suffered in the February 2011 Earthquake.

The Mw 6.2 February 22nd 2011 Christchurch earthquake (and others in the 2010-2011 Canterbury sequence) provided a unique opportunity to study the devastating effects of earthquakes first-hand and learn from them for future engineering applications. All major events in the Canterbury earthquake sequence caused widespread liquefaction throughout Christchurch’s eastern suburbs, particularly extensive and severe during the February 22nd event. Along large stretches of the Avon River banks (and to a lesser extent along the Heathcote) significant lateral spreading occurred, affecting bridges and the infrastructure they support. The first stage of this research involved conducting detailed field reconnaissance to document liquefaction and lateral spreading-induced damage to several case study bridges along the Avon River. The case study bridges cover a range of ages and construction types but all are reinforced concrete structures which have relatively short, stiff decks. These factors combined led to a characteristic deformation mechanism involving deck-pinning and abutment back-rotation with consequent damage to the abutment piles and slumping of the approaches. The second stage of the research involved using pseudo-static analysis, a simplified seismic modelling tool, to analyse two of the bridges. An advantage of pseudo-static analysis over more complicated modelling methods is that it uses conventional geotechnical data in its inputs, such as SPT blowcount and CPT cone resistance and local friction. Pseudo-static analysis can also be applied without excessive computational power or specialised knowledge, yet it has been shown to capture the basic mechanisms of pile behaviour. Single pile and whole bridge models were constructed for each bridge, and both cyclic and lateral spreading phases of loading were investigated. Parametric studies were carried out which varied the values of key parameters to identify their influence on pile response, and computed displacements and damages were compared with observations made in the field. It was shown that pseudo-static analysis was able to capture the characteristic damage mechanisms observed in the field, however the treatment of key parameters affecting pile response is of primary importance. Recommendations were made concerning the treatment of these governing parameters controlling pile response. In this way the future application of pseudo-static analysis as a tool for analysing and designing bridge pile foundations in liquefying and laterally spreading soils is enhanced.

Having a quick but reliable insight into the likelihood of damage to bridges immediately after an earthquake is an important concern especially in the earthquake prone countries such as New Zealand for ensuring emergency transportation network operations. A set of primary indicators necessary to perform damage likelihood assessment are ground motion parameters such as peak ground acceleration (PGA) at each bridge site. Organizations, such as GNS in New Zealand, record these parameters using distributed arrays of sensors. The challenge is that those sensors are not installed at, or close to, bridge sites and so bridge site specific data are not readily available. This study proposes a method to predict ground motion parameters for each bridge site based on remote seismic array recordings. Because of the existing abundant source of data related to two recent strong earthquakes that occurred in 2010 and 2011 and their aftershocks, the city of Christchurch is considered to develop and examine the method. Artificial neural networks have been considered for this research. Accelerations recorded by the GeoNet seismic array were considered to develop a functional relationship enabling the prediction of PGAs. http://www.nzsee.org.nz/db/2013/Posters.htm

Some Canterbury homeowners say their houses have dropped in value because the damage to their properties was inadequately assessed by the Earthquake Commission after the 2010 and 2011 earthquakes. Independent land surveyor, Adrian Cowie, and a Burwood homeowner affected by the quakes, Selwyn Stafford, talk about the issues facing them.

A signpost pointing 'West' and 'East'. The sign pointing West is intact; that indicating East is broken and barely hanging on to the post. Refers to the condition of Christchurch City after the earthquakes of 2010 and 2011; the western wealthier suburbs were less damaged than the poorer Eastern suburbs. Also, progress on repair and rehabilitation of eastern housing had been slow. The redesign of the city centre seemed to be a western suburb priority which ignored the poverty and misery of living conditions on the east. Quantity: 1 digital cartoon(s).

Exactly 75 years ago today, Superman made his debut in "Action Comics" No. 1. Campaigners for the restoration of the Christchurch Cathedral are "thrilled" that rebuilding the earthquake-damaged church remains on the table. The Press reports Christchurch's hotel shortage is so critical that at times visitor centre staff have had to put tourists up in their own homes.

Following the 2010/2011 Canterbury, New Zealand earthquakes, a detailed door-to-door survey was conducted in the Christchurch region to establish the earthquake performance of lightweight timber-framed residential dwellings with a masonry veneer external cladding system. The post-earthquake survey involved documenting the condition of dwellings in areas that had experienced different levels of earthquake shaking, allowing comparison between the performance of different veneer systems and different shaking intensities. In total, just fewer than 1,100 residential dwellings were inspected throughout the wider Christchurch area. The survey included parameters such as level of veneer damage, type of veneer damage, observed crack widths, and level of repair required. It is concluded that based on observed earthquake performance at the shaking intensities matching or exceeding ultimate limit state loading, the post-1996 veneer fixing details performed satisfactorily and continued use of the detail is recommended without further modification.

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.

Christchurch and Canterbury suffered significant housing losses due to the earthquakes. Estimates from the Earthquake Commission (EQC) (2011) suggest that over 150,000 homes (around three quarters of Christchurch housing stock) sustained damage from the earthquakes. Some areas of Christchurch have been declared not suitable for rebuilding, affecting more than 7,500 residential properties.

A small house is shown on an enormous foundation block labelled 'Rate$'. The cartoonist's comment is 'Like for like for the house...Total dislike for the foundation!' In Christchurch there were prospects of large rises in householders' rate to help finance the Christchurch Rebuild project. In view of the damage to housing, rate increases may be badly disproportionate. Quantity: 1 digital cartoon(s).
