A fallen branch caught in weeds in the River Styx. The photographer comments, "This branch was broken off during one of the recent Christchurch earthquakes and fell into the River Styx. Now one side has sprouted roots and the other new buds".

A concrete block wall with a large diagonal crack running through it. The photographer comments, "This wall has fascinated me. It has cracked across in a dead straight diagonal line during one of Christchurch's many earthquakes. How could this have occurred?".

Mural on the side wall of Perry's Cafe on Madras Street. It depicts two work men; one speech bubble saying "Is my crack showing?" and in other other it says "Don't be silly!". A topical joke about the cracks on the wall and Christchurch in general.

Micro - electro - mechanical system (MEMS) based accelerometers are now frequently used in many different parts of our day - to - day lives. It is also increasingly being used for structural testing applications. Researchers have had res ervation of using these devices as they are relatively untested, but now with the wider adoption, it provides a much cheaper and more versatile tool for structural engineering researchers. A number of damaged buildings in the Christchurch Central Business District (CBD) were instrumented with a number of low - cost MEMS accelerometers after the major Christchurch earthquakes. The accelerometers captured extremely high quality building response data as the buildings experienced thousands of aftershocks. This d ata set was amongst one of only a handful of data set s available around the world which provides building response data subjected to real ground motion. Furthermore, due to technological advances, a much larger than usual number of accelerometers has been deployed making the data set one of the most comprehensive available. This data set is utilised to extract modal parameters of the buildings. This paper summarises the operating requirements and preference for using such accelerometers for experimental mod al analysis. The challenges for adapting MEMS based devices for successful modal parameters identification are also discussed.

This paper discusses the seismic performance of the standard RC office building in Christchurch that is given as a structural design example in NZS3101, the concrete structures seismic standard in New Zealand. Firstly the push-over analysis was carried out to evaluate the lateral load carrying capacity of the RC building and then to compare that carrying capacity with the Japanese standard law. The estimated figures showed that the carrying capacity of the New Zealand standard RC office building of NZS3101:2006 was about one third of Japanese demanded carrying capacity. Secondly, time history analysis of the multi-mass system was performed to estimate the maximum response story drift angle using recorded ground motions. Finally, a three-dimensional analysis was carried out to estimate the response of the building to the 22nd February, 2011 Canterbury earthquake. The following outcomes were obtained. 1) The fundamental period of the example RC building is more than twice that of Japanese simplified calculation, 2) The example building’s maximum storey drift angle reached 2.5% under the recorded ground motions. The main purpose of this work is to provide background information of seismic design practice for the reconstruction of Christchurch.

The devastating earthquakes of September 2010 and February 2011 have without question upset the Christchurch City way of life for all. Families and businesses, as well as the natural and built environments have been directly affected, and our social landscapes have since evolved to accommodate the visible changes. Though not perhaps seen as a priority, the Christchurch nightlife has been profoundly altered by the quakes and the once popular CBD clubbing scene has ceased to exist. The concern highlighted in this article is the way in which this has put pressure on suburban bars and the the implications of this for local residents.

Organisations locate strategically within Business Districts (CBDs) in order to cultivate their image, increase their profile, and improve access to customers, suppliers, and services. While CBDs offer an economic benefit to organisations, they also present a unique set of hazard vulnerabilities and planning challenges for businesses. As of May 2012, the Christchurch CBD has been partially cordoned off for over 14 months. Economic activity within the cordoned CBD, which previously contained 6,000 businesses and over 51,000 workers, has been significantly diminished and organisations have been forced to find new ways of operating. The vulnerabilities and resilience of CBDs not only influences outcomes for CBD organisations, but also the broader interconnected (urban/regional/national) system. A CBD is a hub of economic, social, and built infrastructure within a network of links and nodes. When the hub is disrupted all of the people, objects, and transactions that usually flow into and out of the hub must be redirected elsewhere. In an urban situation this means traffic jams in peripheries of the city, increased prices of commercial property, and capital flight; all of which are currently being faced in Canterbury. This report presents the lessons learned from organisations in CBDs affected by the Canterbury earthquakes. Here we focus on the Christchurch CBD; however, several urban town centres were extensively disrupted by the earthquakes. The statistics and discussion presented in this report are based on the results of an ongoing study conducted by Resilient Organisations (www.resorgs.org.nz). The data was captured using two questionnaire surveys of Canterbury organisations (issued November 2010 and May 2011), interviews with key informants, and in-depth case studies of organisations. Several industry sectors were sampled, and geographic samples of organisations in the Christchurch CBD, Lyttelton, and the Kaiapoi town centre were also collected. Results in this report describing “non-CBD organisations” refer to all organisations outside of the Christchurch CBD, Lyttelton, and Kaiapoi town centres.

After a damning report into the CTV building, how many other Christchurch buildings had faults when the earthquake struck? Police investigate the tragic death of a five year old and when so many businesses are struggling, how did the country's big banks increase profits by a quarter?

Topic 1: The Minister for Earthquake Recovery, Gerry Brownlee, was quick to apologise to the Christchurch Mayor Bob Parker for calling him a clown. Topic 2: The Electoral Commission says John Key's hour-long pre-election radio show gave him the chance to raise his personal profile unchallenged.

The word 'faith' has been formed by flowers on the cordon fence beside St John the Baptist Church on Latimer Square. The photographer comments, "If I remember correctly this has been on the fence surrounding the Christchurch earthquake red zone for quite a while and looks remarkably pristine".
