The top of a corner tower from St John the Baptist Church in Latimer Square that has been set between two buttresses at the church's base. Bracing made of steel beams and concrete blocks can be seen fixed to the wall on the right of the photograph.
A photograph of a building on Lichfield Street near Poplar Lane. The facade on the top storey of the building crumbled during the earthquake to reveal the walls underneath. Wire fencing has been placed around the building to keep people from entering.
A photograph of a block of earthquake-damaged buildings on Manchester Street. The outer wall of the second storey has collapsed, the bricks and other rubble spilling onto the footpath. Several cars have been crushed by the falling rubble.
The damaged chimney of a house on the corner of Galbraith Avenue and Avonside Drive. The top section of the chimney has fallen off and the whole chimney has moved away from the building's wall. The chimney has been weather proofed with a yellow tarpaulin.
Damage to the Crichton Cobbers Youth and Community Club. Large sections of the brick walls have collapsed, and two large beams lie across the rubble. Cordon fencing surrounds this and nearby buildings. The photographer comments, "A bike ride around the CBD. Old brewery, later a gym - Fitzgerald Ave".
A dairy on the corner of Gloucester and Woodham Streets. The top wall of the building has crumbled onto the street. A tarpaulin has been placed over the hole to prevent weather damage inside the building. Fencing and road cones cordon off the building along the street.
Damage to a house in Richmond. The brick wall is badly cracked and twisted, and some bricks have fallen, exposing the lining paper and framing below. The photographer comments, "These photos show our old house in River Rd and recovery work around Richmond and St Albans. I think it's broken".

Damage to a house in Richmond. Bricks have fallen from the walls, exposing the wooden framing beneath. Power lines between the house and a power pole have been stretched taut. The photographer comments, "The house and power pole have moved, stretching power lines taut as a guitar string".
A man takes a photograph in the kitchen of a damaged house in Richmond. Behind him, cracks are visible in the walls. The photographer comments, "Revisiting our abandoned house. Kitchen and dining area. (My brother Ross from Invercargill was visiting, he's in several of these)".
A photograph of a room inside a flat on Poplar Street taken during the Residential Access Project. The project gave residents temporary access within the red-zone cordon in order to retrieve items from their homes. The building's outer wall has crumbled leaving the room exposed.
New Zealand’s stock of unreinforced masonry (URM) bearing wall buildings was principally constructed between 1880 and 1935, using fired clay bricks and lime or cement mortar. These buildings are particularly vulnerable to horizontal loadings such as those induced by seismic accelerations, due to a lack of tensile force-resisting elements in their construction. The poor seismic performance of URM buildings was recently demonstrated in the 2011 Christchurch earthquake, where a large number of URM buildings suffered irreparable damage and resulted in a significant number of fatalities and casualties. One of the predominant failure modes that occurs in URM buildings is diagonal shear cracking of masonry piers. This diagonal cracking is caused by earthquake loading orientated parallel to the wall surface and typically generates an “X” shaped crack pattern due to the reversed cyclic nature of earthquake accelerations. Engineered Cementitious Composite (ECC) is a class of fiber reinforced cement composite that exhibits a strain-hardening characteristic when loaded in tension. The tensile characteristics of ECC make it an ideal material for seismic strengthening of clay brick unreinforced masonry walls. Testing was conducted on 25 clay brick URM wallettes to investigate the increase in shear strength for a range of ECC thicknesses applied to the masonry wallettes as externally bonded shotcrete reinforcement. The results indicated that there is a diminishing return between thickness of the applied ECC overlay and the shear strength increase obtained. It was also shown that, the effectiveness of the externally bonded reinforcement remained constant for one and two leaf wallettes, but decreased rapidly for wall thicknesses greater than two leafs. The average pseudo-ductility of the strengthened wallettes was equal to 220% of that of the as-built wallettes, demonstrating that ECC shotcrete is effective at enhancing both the in-plane strength and the pseudo-ductility of URM wallettes.
