A digitally manipulated photograph of the foyer of the Christchurch Art Gallery. The photographer comments, "The Christchurch art gallery has been closed to the public since the February 2011 earthquake and its reopening seems to be in the distant future. I want to convey the feeling that if art is not looked at darkness starts to overcome it and the paint starts to peel off".

A view down Chancery Lane through cordon fencing. A sign reading "No Entry" is posted on the fence, and fallen leaves have accumulated around the fence and buildings. The photographer comments, "Chancery Lane in the Christchurch CBD red zone looks like it has had no one through at all since the February earthquake".

A magnitude six earthquake which struck in Canterbury just before quarter-past-nine Wednesday morning has left some nearby residents feeling a bit shaken. The quake, which struck 45 kilometres north of Geraldine at a depth of ten kilometres, was located in the Southern Alps, away from populated areas. It was widely felt in Geraldine, Timaru and Temuka - though there are no reports of serious damage or injury. Timaru District Council says it's closing a stadium and other facilities for assessment. Two people who experienced the quake, Janene Adams who's deputy chair of the Geraldine Community Board, and from further north, and the operator of the Mount Somers Holiday Park, Maureen Meanwell, spoke with Charlotte Cook

Unreinforced masonry (URM) cavity-wall construction is a form of masonry where two leaves of clay brick masonry are separated by a continuous air cavity and are interconnected using some form of tie system. A brief historical introduction is followed by details of a survey undertaken to determine the prevalence of URM cavity-wall buildings in New Zealand. Following the 2010/2011 Canterbury earthquakes it was observed that URM cavity-walls generally suffered irreparable damage due to a lack of effective wall restraint and deficient cavity-tie connections, combined with weak mortar strength. It was found that the original cavity-ties were typically corroded due to moisture ingress, resulting in decreased lateral loadbearing capacity of the cavity-walls. Using photographic data pertaining to Christchurch URM buildings that were obtained during post-earthquake reconnaissance, 252 cavity-walls were identified and utilised to study typical construction details and seismic performance. The majority (72%, 182) of the observed damage to URM cavity-wall construction was a result of out-of-plane type wall failures. Three types of out-of-plane wall failure were recognised: (1) overturning response, (2) one-way bending, and (3) two-way bending. In-plane damage was less widely observed (28%) and commonly included diagonal shear cracking through mortar bed joints or bricks. The collected data was used to develop an overview of the most commonly-encountered construction details and to identify typical deficiencies in earthquake response that can be addressed via the selection and implementation of appropriate mitigation interventions. http://www.journals.elsevier.com/structures
