University of Canterbury geologist Mark Quigley has earned a reputation for being a great science communicator on the subject of earthquakes. But when he's not in the media spotlight, he's out and about around Canterbury building a picture of the region's tectonic history, and trying to understand what might happen in the future.

The connections between walls of unreinforced masonry (URM) buildings and flexible timber diaphragms are critical building components that must perform adequately before desirable earthquake response of URM buildings may be achieved. Field observations made during the initial reconnaissance and the subsequent damage surveys of clay brick URM buildings following the 2010/2011 Canterbury, New Zealand earthquakes revealed numerous cases where anchor connections joining masonry walls or parapets with roof or floor diaphragms appeared to have failed prematurely. These observations were more frequent for adhesive anchor connections than for through-bolt connections (i.e. anchorages having plates on the exterior façade of the masonry walls). Subsequently, an in-field test program was undertaken in an attempt to evaluate the performance of adhesive anchor connections between unreinforced clay brick URM walls and roof or floor diaphragms. The study consisted of a total of almost 400 anchor tests conducted in eleven existing URM buildings located in Christchurch, Whanganui and Auckland. Specific objectives of the study included the identification of failure modes of adhesive anchors in existing URM walls and the influence of the following variables on anchor load-displacement response: adhesive type, strength of the masonry materials (brick and mortar), anchor embedment depth, anchor rod diameter, overburden level, anchor rod type, quality of installation and the use of metal mesh sleeve. In addition, the comparative performance of bent anchors (installed at an angle of minimum 22.5o to the perpendicular projection from the wall surface) and anchors positioned horizontally was investigated. Observations on the performance of wall-to-diaphragm connections in the 2010/2011 Canterbury earthquakes, a snapshot of the performed experimental program and the test results and a preliminary proposed pull-out capacity of adhesive anchors are presented herein.

A residential property in Bexley with an overgrown garden. Weeds are growing out onto the footpath. The photographer comments, "Today I took a drive around the residential area between Bexley and New Brighton. It was a stark reminder to be thankful for the situation we're in and perhaps not complain too much that our garden wall hasn't yet been rebuilt".

A photograph of students from the School of Design at the University of Technology Sydney constructing Eye of the Storm out of blue tarpaulin flags. The flags were strung across Worcester Street bridge for Canterbury Tales - a carnivalesque procession which was the main event of FESTA 2013.

A photograph of painted bird cut-outs hanging from a tree next to the Avon River on Oxford Terrace, near the Worcester Street bridge. The decorations were part of an installation titled The River, created by students from Lincoln University's School of Landscape Architecture for Canterbury Tales, a carnivalesque procession and the main event of FESTA 2013.

The "Tree of Hope" at the River of Flowers event held in Riccarton Bush, commemorating the second anniversary of the 22 February earthquake. The photographer comments, "Luggage labels and pens were supplied, and people were encouraged to write a message of hope for Christchurch and tie it to the tree. Although the turn-out this year was just as big as last year's, there were not as many messages tied to the tree - perhaps we're all feeling less hopeful this year".

Mike Rutledge and zoologist Meg Selby are new owners of Nelson's Natureland Zoo and a mob of meerkats, an African porcupine, and a menagerie of native birds and farm animals. The Orana Wildlife Trust took over the care of the Tahunanui zoo in 2008, but the financial strain caused by the Canterbury earthquakes has been too much. The zoo has been around since 1966. The Nelson City Council, which owns the land, called for expressions of interest last year when Orana decided to pull out and Meg and Mike got the nod. They will be taking over in November.

A photograph of a sofa made out of car tyres and a pallet at Rock on Eastside on the corner of Aldwins Road and Linwood Avenue. Rock on Eastside was a outdoor lounge and art space facilitated by Gap Filler and Youthtown. The sofa was made by students from the University of Canterbury Student Volunteer Army. Painted rocks have been placed in front of the sofa as decoration.

There are occasional sewerage spills into the Avon River while all the sewer and road repairs are carried out. This rock wall was level and well above high tide level prior to the eathquakes. All the houses that can been seen here (except for those on the distant Port Hills) are in the suburban "red zone" and are still to be demolished.

An aerial photograph of Manchester Street near Cambridge Terrace. The photograph has been captioned by BeckerFraserPhotos, "The new Christchurch emerges - more colourful than before. The tree wrapped in high visibility is another project from artist Peter Majendie. The newly planted grass on the right hand side of the photo is on the PGC site and an adjoining site and is a CERA initiative. In the foreground of the photos the former site of St Luke's is now attractively laid out, while the splendour of the trees on the site can be fully appreciated".

Two cardboard coffee cups in a takeaway tray sit on a wooden counter. The photographer comments, "What is the story of these coffees and that sad muffin? Were these an order when the earthquake struck Christchurch on 22 February 2011? Were these a workman's and a colleague's having a quick coffee break when a later aftershock caused them to leave everything behind when they fled the red zoned building, or were they just forgotten when the building was cleared out and abandoned?".
