Detail of a section of the brick wall on the Weston House which has crumbled.
A brick wall has fallen from this house, exposing the rooms within and leaving a pile of rubble in front. The ceiling has slumped and is held up with jacks. The photographer comments, "This was probably the result of the shallower February Christchurch earthquake rather than the bigger September one".
The word "red" has been spray painted across a brick wall that has been mostly demolished.

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

A digitally manipulated image of the word 'Lyttelton' made out of damaged bricks. The photographer comments, "This shows the courage and humour of the earthquake wrecked port of Lyttelton. There is lots of little things that make you smile that the locals and volunteers from around the area have created".
Damage to the Knox Church. The brick walls of the church have collapsed, but the woodwork ceiling is still intact.

Detail of damage to the former Princess Cinema in New Brighton. Bricks have fallen from the wall, exposing the interior. The photographer comments, "This is the back of the old Princess Cinema in New Brighton after the earthquake in Christchurch, New Zealand on 22 February. The bricks seem to be just on the edge of falling. This building has now been knocked down as it was so dangerous".
Damage to The Bone Dude's Bone Carving Studio and Cultured Gallery on Fitzgerald Avenue. The brick wall is cracked, and the guttering has fallen. The photographer comments, "This building was damaged in the September earthquake in Christchurch. It was the Bone dude's bone carving studio. The motto on the wall was 'Carve your own' and it looks like the earthquakes did just that".
