Two days after the 22 February 2011 M6.3 earthquake in Christchurch, New Zealand, three of the authors conducted a transect of the central city, with the goal of deriving an estimate of building damage levels. Although smaller in magnitude than the M7.1 4 September 2010 Darfield earthquake, the ground accelerations, ground deformation and damage levels in Christchurch central city were more severe in February 2011, and the central city was closed down to the general public. Written and photographic notes of 295 buildings were taken, including construction type, damage level, and whether the building would likely need to be demolished. The results of the transect compared favourably to Civil Defence rapid assessments made over the following month. Now, more than one year and two major aftershocks after the February 2011 earthquake these initial estimates are compared to the current demolition status to provide an updated understanding of the state of central Christchurch.

Text top left reads 'Downsizemic activity' and a seismic graph zigzags wildly but gradually tails off into the words 'Interest rates' which take a serious downwards trend. Context - The Christchurch earthquakes of 4 September 2010 and 22 February 2011 which have had an impact on an already stagnating economy. The Reserve Bank has made a relatively large 50-point cut in its benchmark interest rate, the Official Cash Rate (from 3% to 2.5 per cent). Critics say that inflation is already running unacceptably high and there is a threat of much higher inflation in a year or two when the rebuilding of Christchurch begins to put pressure on limited resources. The Reserve Bank acknowledged these factors, but it has chosen instead to focus on the immediate impact of the earthquake on the economy and particularly on all-important business and consumer sentiment.

The cartoon shows the hands of two people joined in mutual despair and kindness. One represents 'Christchurch' and the other the 'Pike River Mine'. Context - the 7.1 earthquake on 4 September 2010 in Christchurch in which there was a lot of damage but no deaths, the Pike River Mine disaster which occurred on the West Coast on 19 November 2010 and caused the deaths of 29 coal miners and now on 22 February 2011 a 6.3 magnitude earthquake in Christchurch which has probably killed more than 200 people (at this point the number is still not known) and caused much more severe damage. The reason the apparently lesser magnitude quake caused more destruction is because it was very shallow, was in the middle of the day and struck very close to the centre of the city.

A man walks away from a scene of destruction after an earthquake; he is reading a newspaper whose headline is 'ACC takes earthquake hit' and because he is not looking where he is going he is about to step into the sea in which lurks a shark that represents 'levies'. A second version has the shark representing 'Nick Smith'. Context - The second Christchurch more devastating earthquake of 22 February 2011 that followed an original earthquake on 4 September 2010. Levy changes from April 1 will give businesses discounts or penalties on their workplace ACC levies based on a three-year claims history but ACC Minister Nick Smith said today that the quake would be declared an "adverse event" so Christchurch employers would not be unfairly hit with a levy increase, unless they contributed materially to an employee's injuries.

In six small cameos Prime Minister John Key ponders over things economic and ends up dancing; he says 'I'm bereft of ideas for the economy gambling the lives of our troops in the Afghanistan mess I'm presiding over the biggest budget deficit in our history borrowing $300m a week to cushion our slide into oblivion Using lots of World Cup piffle to distract from the real issues Yet I'm still rating miles higher than Goff so how hopeless is he??? A little man in the last frame comments 'Spoiled for choice eh?' Context - New Zealand's rather dire economic situation made so much worse by the Christchurch earthquakes of 4 September 2010 and 22 February 2011, the consistently high poll rating of John Key and the series of disasters suffered by the Labour Party in the run up to the 2011 election in November.

The cartoon shows the Christchurch Anglican Cathedral tower in ruins and without its steeple. Above the drawing is the date '22.2.11'. A second version shows a huge magnitude 6.3 earthquake tremor on a seismic graph on top of which is the date '22.2.11'. Context - On 22 February 2011 at 12:51 pm (NZDT), Christchurch experienced a major magnitude 6.3 earthquake, which resulted in severe damage and many casualties. A National State of Emergency has been declared. The cathedral tower has collapsed and there has been devastating damage to the remaining structure. The Cathedral is one of around six sites of extreme concern around the city where many are believed to still be trapped. This earthquake followed on from an original magnitude 7.1 earthquake on 4 September 2010 which did far less damage and in which no-one died.

The University of Canterbury Dept. of Chemistry has weathered the Canterbury Earthquake of September 4, 2010 very well due to a combination of good luck, good planning and dedicated effort. We owe a great deal to university Emergency Response Team and Facilities Management Personnel. The overall emergency preparedness of the university was tested to a degree far beyond anything else in its history and shown to be well up to scratch. A strong cooperative relationship between the pan-campus controlling body and the departmental response teams greatly facilitated our efforts. Information and assistance was provided promptly, as and when we needed it without unnecessary bureaucratic overheads. At the departmental level we are indebted to the technical staff who implemented the invaluable pre-quake mitigation measures and carried the majority of the post-quake clean-up workload. These people put aside their personal concerns and anxieties at a time when magnitude-5 aftershocks were still a regular occurrence.

On 4 September 2010, a magnitude Mw 7.1 earthquake struck the Canterbury region on the South Island of New Zealand. The epicentre of the earthquake was located in the Darfield area about 40 km west of the city of Christchurch. Extensive damage was inflicted to lifelines and residential houses due to widespread liquefaction and lateral spreading in areas close to major streams, rivers and wetlands throughout Christchurch and Kaiapoi. Unreinforced masonry buildings also suffered extensive damage throughout the region. Despite the severe damage to infrastructure and residential houses, fortunately, no deaths occurred and only two injuries were reported in this earthquake. From an engineering viewpoint, one may argue that the most significant aspects of the 2010 Darfield Earthquake were geotechnical in nature, with liquefaction and lateral spreading being the principal culprits for the inflicted damage. Following the earthquake, an intensive geotechnical reconnaissance was conducted to capture evidence and perishable data from this event. This paper summarizes the observations and preliminary findings from this early reconnaissance work.

This paper presents insights from recent advanced laboratory testing of undisturbed and reconstituted specimens of Christchurch silty-sands. The purpose of the testing was to establish the cyclic strength of silty-sands from sites in the Central Business District (CBD), where liquefaction was observed in 4 September 2010, 22 February 2011, and 13 June 2011. Similar overall strengths were obtained from undisturbed and reconstituted tests prepared at similar densities, albeit with higher variability for the reconstituted specimens. Reconstituted specimens exhibited distinctly different response in terms of lower compressibility during initial loading cycles, and exhibited a more brittle response when large strains were mobilised, particularly for samples with high fines content. Given the lower variability in natural sample response and the possibility of age-related strength to be significant for sites not subjected to earthquakes, high quality undisturbed samples are recommended over the use of reconstituted specimens to establish the cyclic strength of natural sands.

This paper presents the preliminary findings of a study on the resilience and recovery of organisations following the Darfield earthquake in New Zealand on 4 September 2010. Sampling included organisations proximal and distal to the fault trace, organisations located within central business districts, and organisations from seven diverse industry sectors. The research captured information on the challenges to, the impacts on, and the reflections of the organisations in the first months of recovery. Organisations in central business districts and in the hospitality sector were most likely to close while organisations that had perishable stock and livestock were more heavily reliant on critical services. Staff well-being, cash flow, and customer loss were major concerns for organisations across all sectors. For all organisations, the most helpful factors in mitigating the effects of the earthquake to be their relationship with staff, the design and type of buildings, and critical service continuity or swift reinstatement of services.

Much of the CBD is still cordoned off and without power (as you should be able to spot) as a result of the damage caused by February's deadly earthquake. This photo clearly shows the extent of the lean that the Hotel Grand Chancellor is now on. Apparently it is out by 1m at the top leaning east. Demolition will start about mid June and is expec...

The 4th of September 2010 Mw 7.1 Darfield (Canterbury) earthquake had generated significant ground shaking within the Christchurch Central Business District (CBD). Despite the apparently significant shaking, the observed structural damage for pre-1970s reinforced concrete (RC) buildings was indeed limited and lower than what was expected for such typology of buildings. This paper explores analytically and qualitatively the different aspects of the "apparent‟ good seismic performance of the pre-1970s RC buildings in the Christchurch CBD, following the earthquake reconnaissance survey by the authors. Damage and building parameters survey result, based on a previously established inventory of building stock of these non-ductile RC buildings, is briefly reported. From an inventory of 75 buildings, one building was selected as a numerical case-study to correlate the observed damage with the non-linear analyses. The result shows that the pre-1970s RC frame buildings performed as expected given the intensity of the ground motion shaking during the Canterbury earthquake. Given the brittle nature of this type of structure, it was demonstrated that more significant structural damage and higher probability of collapse could occur when the buildings were subjected to alternative input signals with different frequency content and duration characteristics and still compatible to the seismicity hazard for Christchurch CBD.

Maybe it should be titled "Pray Here"! The old church buildings next to the Christchurch Basilica (Cathedral of the Blessed Sacrament) have been demolished and replaced with ANOTHER Wilson's Car Park. Hundreds of sites in the city where buildings have been demolished after the earthquakes have been replaced in the short term by car parks!

The M7.1 Darfield earthquake shook the town of Christchurch (New Zealand) in the early morning on Saturday 4th September 2010 and caused damage to a number of heritage unreinforced masonry buildings. No fatalities were reported directly linked to the earthquake, but the damage to important heritage buildings was the most extensive to have occurred since the 1931 Hawke‟s Bay earthquake. In general, the nature of damage was consistent with observations previously made on the seismic performance of unreinforced masonry buildings in large earthquakes, with aspects such as toppled chimneys and parapets, failure of gables and poorly secured face-loaded walls, and in-plane damage to masonry frames all being extensively documented. This report on the performance of the unreinforced masonry buildings in the 2010 Darfield earthquake provides details on typical building characteristics, a review of damage statistics obtained by interrogating the building assessment database that was compiled in association with post-earthquake building inspections, and a review of the characteristic failure modes that were observed.

Maori Party MP for Te Tai Tonga, Rahui Katene' is buried up to her neck in earthquake rubble as she reads a newspaper headline referring to her statement that the aftermath of the earthquake has demonstrated 'racism and ethnic profiling'. Rahui Katene's head is disintegrating and two engineers who are examining the damage decide that 'This can't be repaired, it needs to be condemned'. Rahui Katene says the authorities, who kicked a Christchurch family out of a welfare centre that was set up after the Christchurch earthquake that struck on the 4th September, should apologise for judging them too early and shaming them publicly. Mrs Katene was also concerned about claims that Maori youth were being targeted by police. "I've heard from whanau that in one particular area rangatahi who were volunteering in their community and helping their whanau were accused by police of theft. The whanau are trying to work these issues through with the police, but I'm growing concerned about what appears to be ethnic profiling." Quantity: 1 digital cartoon(s).

Two huge wrestlers, one representing 'Port Hills fault' and the other 'Greendale fault' struggle together over a broken Christchurch. Another wrestler, representing 'Other faults' appears in the distance yelling 'Is it my turn yet?' Context - Christchurch has now had three major earthquakes and thousands of aftershocks. It now appears likely that the Christchurch quakes resulted from activity on a fault extending directly eastward from the Alpine fault that remained unknown until last year, says Roger Musson, a seismologist at the British Geological Survey in Edinburgh. The new fault first came to light last September (4th) when a stronger but less calamitous quake shook Darfield, 40 kilometres west of Christchurch. Musson says the latest quake (Feb 22, 2011) probably resulted from an eastward continuation of activity on the same fault. "It has probably not moved for tens of thousands of years, so lots of strain built up," says Musson. The third major quake happened on 13th June 2011.

This paper concerns the explicit consideration of near-fault directivity in conventional ground motion prediction models, and its implication for probabilistic seismic hazard analysis (PSHA) in New Zealand. The proposed approach utilises recently developed models by Shahi & Baker (2011), which account for both the 'narrowband' nature of the directivity pulse on spectral ordinates, and the probability of pulse occurrence at the site of interest. Furthermore, in order to correctly consider directivity, distributed seismicity sources are considered as finite-faults, as opposed to their (incorrect) conventional treatment as point-sources. The significance of directivity on hazard analysis results is illustrated for various vibration periods at generic sites located in Christchurch and Otira, two locations whose seismic hazard is comprised of notably different seismic sources. When compared to the PSHA results considering directivity and distributed seismicity as finite faults, it is shown that the NZS1170.5:2004 directivity factor is notably unconservative for all vibration periods in Otira (i.e. high seismic hazard region); and unconservative for Christchurch at short-to-moderate vibration periods ( < 3s); but conservative at long periods ( > 4s).

© 2018 Springer Nature B.V. This study compares seismic losses considering initial construction costs and direct-repair costs for New Zealand steel moment-resisting frame buildings with friction connections and those with extended bolted-end-plate connections. A total of 12 buildings have been designed and analysed considering both connection types, two building heights (4-storey and 12-storey), and three locations around New Zealand (Auckland, Christchurch, and Wellington). It was found that buildings with friction connections required design to a higher design ductility, yet are generally stiffer due to larger beams being required to satisfy higher connection overstrength requirements. This resulted in the frames with friction connections experiencing lower interstorey drifts on most floors but similar peak total floor accelerations, and subsequently incurring lower drift-related seismic repair losses. Frames with friction connections tended to have lower expected net-present-costs within 50 years of the building being in service for shorter buildings and/or if located in regions of high seismicity. None of the frames with friction connections in Auckland showed any benefits due to the low seismicity of the region.

4th September 2010 a 7.1 magnitude earthquake strikes near Christchurch, New Zealand’s second largest city of approximately 370,000 people. This is followed by a 6.3 magnitude quake on 22nd February 2011 and a 6.4 on 13th June. In February 181 people died and a state of national emergency was declared from 23 February to 30th April. Urban Search and Rescue teams with 150 personnel from New Zealand and 429 from overseas worked tirelessly in addition to Army, Police and Fire services. Within the central business district 1,000 buildings (of 4,000) are expected to be demolished. An estimated 10,000 houses require demolition and over 100,000 were damaged. Meanwhile the over 7,000 aftershocks have become part of the “new normal” for us all. During this time how have libraries supported their staff? What changes have been made to services? What are the resourcing opportunities? This presentation will provide a personal view from Lincoln University, Te Whare Wanaka o Aoraki, Library Teaching and Learning. Lincoln is New Zealand's third oldest university having been founded in 1878. Publicly owned and operated it is New Zealand's specialist land-based university. Lincoln is based on the Canterbury Plains, 22 kilometres south of Christchurch. On campus there was mostly minor damage to buildings while in the Library 200,000 volumes were thrown from the shelves. I will focus on the experiences of the Disaster Team and on our experiences with hosting temporarily displaced staff and students from the Christchurch Polytechnic Institute of Technology, Library, Learning & Information Services. Experiences from two other institutions will be highlighted: Christchurch City Libraries, Ngā Kete Wānanga-o-Ōtautahi. Focusing on the Māori Services Team and the Ngā Pounamu Māori and Ngāi Tahu collections. The Central library located within the red zone cordon has been closed since February, the Central library held the Ngā Pounamu Māori and Ngai Tahu collections, the largest Māori collections in the Christchurch public library network. The lack of access to these collections changed the way the Māori Services Team, part of the larger Programmes, Events and Learning Team at Christchurch City Libraries were able to provide services to their community resulting in new innovative outreach programmes and a focus on promotion of online resources. On 19th December the “temporary” new and smaller Central library Peterborough opened. The retrieved Ngā Pounamu Māori and Ngai Tahu collections "Ngā rakau teitei e iwa”, have since been re-housed and are once again available for use by the public. Te Rūnanga o Ngāi Tahu. This organisation, established by the Te Rūnanga o Ngāi Tahu Act 1996, services the statutory rights for the people of Ngāi Tahu descent and ensures that the benefits of their Treaty Claim Settlement are enjoyed by Ngāi Tahu now and in the future. Ngāi Tahu are the indigenous Māori people of the southern islands of New Zealand - Te Waipounamu. The iwi (people) hold the rangatiratanga or tribal authority to over 80 per cent of the South Island. With their headquarters based in the central business they have also had to be relocated to temporary facilities. This included their library/archive collection of print resources, art works and taonga (cultural treasures).
