Damaged masonry at the top of the former Canterbury Jockey Club building on Oxford Terrace.
A vehicle that has been smashed by fallen masonry from the Cathedral of the Blessed Sacrament.
A pile of bricks and masonry in the car park of the Music Centre of Christchurch.
A photograph of the earthquake damage to the old Registry Building on the corner of Worcester and Montreal Streets. The masonry of the Worcester Street gable has crumbled and is lying on the street in front. Wire fencing has been used to cordon off the building.
A car which was crushed by falling masonry from Wave House (Winnie Bagoes Pizza Bar) on Gloucester Street during the 22 February 2011 earthquake. Emergency personnel have spray painted the car with the word "Clear" to indicate it has been checked for trapped or injured people.
A photograph of the Durham Street Methodist Church which collapsed during the 22 February 2011 earthquake. All that is left is a small section of the front wall. A large pile of masonry sits in front. To the left, scaffolding indicates the height of the building before it collapsed.
A photograph of cordon fences around a building on Cashel Street. Road cones have also been placed around the building and the word "Danger" has been spray-painted on the footpath in front. Fallen masonry from the building lies on the footpath in front.
A photograph of the Durham Street Methodist Church on Durham Street. The church has almost completely collapsed and only a small section of the structure is still standing. Masonry and other rubble has spilled onto the footpath and street in front.
A photograph of Cranmer Courts on the corner of Kilmore and Montreal Streets. Pieces of masonry and chimneys have been removed from the building and placed on the ground in front. Wire fencing and road cones have been placed around the building to create a cordon.
A photograph of emergency management personnel crossing the intersection of High, Colombo, and Hereford Streets. In the background is the earthquake-damaged Fisher's Building. Large sections of the top storey have collapsed, the masonry spilling onto the footpath and damaging the awning.
A photograph of the earthquake damage to the Canterbury Provincial Chambers Building on Durham Street. Large sections of the masonry have collapsed, spilling onto the road. Wire fencing has been placed around the building as a cordon. Scaffolding erected up the side has collapsed.

St Elmo Courts, a NZHPT heritage building on the corner of Hereford and Montreal Streets. The building was severely damaged during the 4 September earthquake, with diagonal cracking between the windows. Scaffolding has been placed around the bottom of the building.
Seismic retrofitting of unreinforced masonry buildings using posttensioning has been the topic of many recent experimental research projects. However, the performance of such retrofit designs in actual design level earthquakes has previously been poorly documented. In 1984 two stone masonry buildings within The Arts Centre of Christchurch received posttensioned seismic retrofits, which were subsequently subjected to design level seismic loads during the 2010/2011 Canterbury earthquake sequence. These 26 year old retrofits were part of a global scheme to strengthen and secure the historic building complex and were subject to considerable budgetary constraints. Given the limited resources available at the time of construction and the current degraded state of the steel posttension tendons, the posttensioned retrofits performed well in preventing major damage to the overall structure of the two buildings in the Canterbury earthquakes. When compared to other similar unretrofitted structures within The Arts Centre, it is demonstrated that the posttensioning significantly improved the in-plane and out-of-plane wall strength and the ability to limit residual wall displacements. The history of The Arts Centre buildings and the details of the Canterbury earthquakes is discussed, followed by examination of the performance of the posttension retrofits and the suitability of this technique for future retrofitting of other historic unreinforced masonry buildings. http://www.aees.org.au/downloads/conference-papers/

The damaged Cranmer Courts on the corner of Kilmore and Montreal Streets. The corner of the building has crumbled onto the street, which is now littered with broken masonry. Wire fencing placed around the building after the 4 September 2010 earthquake has managed to keep the debris away from the road.
A photograph of the earthquake damage to the Canterbury Provincial Chambers on Durham Street. The top of one of the chambers has crumbled and the masonry has fallen onto the footpath. Scaffolding which was erected after the 4 September 2010 earthquake has also fallen. Wire fences have been placed around the building as a cordon.
A photograph of the Observatory tower at the Christchurch Arts Centre. There are cracks in the masonry of the tower near where the two storeys join. The cracks formed as a result of the 4 September 2010 earthquake. Wire fencing has been placed at the entrance to the courtyard in front as a cordon.
A photograph of the earthquake damage to the former Canterbury Public Library on the corner of Hereford Street and Cambridge Terrace. The bricks in the corner of the building have crumbled and masonry can be seen on the footpath below. Wire fences have been placed around the building as a cordon.
