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 photograph of a member of the Wellington Emergency Management Office Emergency Response Team standing in front of the earthquake-damaged Avonmore House on Hereford Street. Sections of the walls have crumbled, spilling bricks and masonry onto the footpath and street below. Many of the windows have warped, breaking the glass. USAR codes have been spray-painted on one of the columns. A red sticker taped to the door indicates that the building is unsafe to enter.

A house in Christchurch with a red sticker on the window indicating that it is unsafe to enter. "No entry" and a large cross have also been spray painted on the front fence to warn people off. On the right side of the house, a tarpaulin can be seen covering a collapsed brick wall.
Internal damage to a house in Richmond. A large crack in the wallboard below a window has exposed the bricks, and the skirting board has moved away from the floor. The photographer comments, "Cracks in the wall of the sunroom. This is the interior view of the crack in the previous shot".
It is well known that buildings constructed using unreinforced masonry (URM) are susceptible to damage from earthquake induced lateral forces that may result in partial or full building collapse. The 2010/2011 Canterbury earthquakes are the most recent New Zealand example of destructive earthquakes, which have drawn people's attention to the inherent seismic weaknesses of URM buildings and anchored masonry veneer systems in New Zealand. A brief review of the data collected following the 2010 Darfield earthquake and more comprehensive documentation of data that was collected following the 2011 Christchurch earthquake is presented, along with the findings from subsequent data interrogation. Large stocks of earthquake prone vintage URM buildings that remain in New Zealand and in other seismically active parts of the world result in the need for minimally invasive and cost effective seismic retrofit techniques. The principal objective of the doctoral research reported herein was to investigate the applicability of near surface mounted (NSM) carbon fibre reinforced polymer (CFRP) strips as a seismic improvement technique. A comprehensive experimental program consisting of 53 pull tests is presented and is used to assess the accuracy of existing FRP-to-masonry bond models, with a modified model being proposed. The strength characteristics of vintage clay brick URM wall panels from two existing URM buildings was established and used as a benchmark when manufacturing replica clay brick test assemblages. The applicability of using NSM CFRP strips as a retrofitting technique for improving the shear strength and the ductility capacity of multi-leaf URM walls constructed using solid clay brick masonry is investigated by varying CFRP reinforcement ratios. Lastly, an experimental program was undertaken to validate the proposed design methodology for improving the strength capacity of URM walls. The program involved testing full-scale walls in a laboratory setting and testing full-scale walls in-situ in existing vintage URM buildings. Experimental test results illustrated that the NSM CFRP technique is an effective method to seismically strengthen URM buildings.
A photograph of the earthquake damage to the Knox Church on the corner of Bealey Avenue and Victoria Street. The gable walls have crumbled, exposing the wooden structure inside. Wire fencing, road cones and cordon tape have been placed around the building as a cordon.
Damage to Lyttelton following the 22 February 2011 earthquake. Forbes' Store on Norwich Quay with a broken awning and damage visible on the brick walls. Scaffolding placed around the building since the 4 September 2010 earthquake has tumbled during the 22 February 2011 earthquake.
