The sequence of earthquakes that has greatly affected Christchurch and Canterbury since September 2010 has again demonstrated the need for seismic retrofit of heritage unreinforced masonry buildings. Commencing in April 2011, the damage to unreinforced stone masonry buildings in Christchurch was assessed and recorded with the primary objective being to document the seismic performance of these structures, recognising that they constitute an important component of New Zealand’s heritage architecture. A damage statistics database was compiled by combining the results of safety evaluation placarding and post-earthquake inspections, and it was determined that the damage observed was consistent with observations previously made on the seismic performance of stone masonry structures in large earthquakes. Details are also given on typical building characteristics and on failure modes observed. Suggestions on appropriate seismic retrofit and remediation techniques are presented, in relation also to strengthening interventions that are typical for similar unreinforced stone masonry structures in Europe.

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 video of an interview with relatives of Earl Nicholas and May Stick about the Coroner's Inquest into the 22 February 2011 earthquake. Nicholas and Stick lost their lives during the 22 February 2011 earthquake when the bus they were travelling in was crushed by falling masonry.

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.
