Damage to a house in Richmond. Bricks have fallen from the walls onto the driveway, and a large gap between the concrete foundation and the wooden framing shows how much the house has moved. The photographer comments, "The foundations and brick cladding moved, but the timber wall remained in position. The gap grew to over 400mm by the time the house was demolished.

A photograph of the earthquake-damaged Our City O-Tautahi Building on the corner of Worcester Street and Oxford Terrace. Steel bracing has been placed against the building to secure the brick walls. The bracing is supported by large concrete blocks. Wire fences have also been placed around the bottom of the building as a cordon. Scaffolding has been erected around the tower to the right.
Effect of Loading Rate on Response of Reinforced Concrete Prisms
Research papers, University of Canterbury Library
Research following the 2010-2011 Canterbury earthquakes investigated the minimum vertical reinforcement required in RC walls to generate well distributed cracking in the plastic hinge region. However, the influence of the loading sequence and rate has not been fully addressed. The new minimum vertical reinforcement limits in NZS 3101:2006 (Amendment 3) include consideration of the material strengths under dynamic load rates, but these provisions have not been validated at a member or system level. A series of tests were conducted on RC prisms to investigate the effect of loading rate and sequence on the local behaviour of RC members. Fifteen axially loaded RC prisms with the designs representing the end region of RC walls were tested under various loading rates to cover the range of pseudo-static and earthquake loading scenarios. These tests will provide substantial data for understanding the local behaviour of RC members, including hysteretic load-deformation behaviour, crack patterns, failure mode, steel strain, strain rate and ductility. Recommendations will be made regarding the effect of loading rate and reinforcement content on the cracking behaviour and ductility of RC members.

The steps from Cambridge Terrace up to the Bridge of Remembrance. The terracotta tiles on the highest step have chipped off. The gaps that can be seen on the concrete wall to the right shows how far the steps have moved from their original position.

A photograph captioned by BeckerFraserPhotos, "The failed column near the south-east corner of the ground floor of the Hotel Grand Chancellor. This corner of the building slumped 700mm when this column and a nearby sheer wall failed. Scaffolding was erected all around it and then sprayed with concrete to stabilise the building".

Inventory and seismic assessment of earthquake-vulnerable masonry and conc…
Research papers, The University of Auckland Library
Following the 2010–2011 Canterbury earthquakes, a renewed focus has been directed across New Zealand to the hazard posed by the country‘s earthquake-vulnerable buildings, namely unreinforced masonry (URM) and reinforced concrete (RC) buildings with potentially nonductile components that have historically performed poorly in large earthquakes. The research reported herein was pursued with the intention of addressing several recommendations made by the Canterbury Earthquakes Royal Commission of Inquiry which were classified into the following general categories: Identification and provisional vulnerability assessment of URM and RC buildings and building components; Testing, assessment, and retrofitting of URM walls loaded out-of-plane, with a particular focus on highly vulnerable URM cavity walls; Testing and assessment of RC frame components, especially those with presumably non-ductile reinforcement detailing; Portfolio management considering risks, regulations, and potential costs for a portfolio that includes several potentially earthquake-vulnerable buildings; and Ongoing investigations and proposed research needs. While the findings from the reported research have implications for seismic assessments of buildings across New Zealand and elsewhere, an emphasis was placed on Auckland given this research program‘s partnership with the Auckland Council, the Auckland region accounting for about a third each of the country‘s population and economic production, and the number and variety of buildings within the Auckland building stock. An additional evaluation of a historic building stock was carried out for select buildings located in Hawke‘s Bay, and additional experimental testing was carried out for select buildings located in Hawke‘s Bay and Christchurch.
