A video about field trials conducted by the Department of Building and Housing at Queen Elizabeth II Park in Christchurch. Fifty kilograms of explosives are being used to simulate a magnitude-4 earthquake at a distance of 10 kilometres. The aim of the trials is to test soil-strengthening techniques that could be used to repair damaged land in Christchurch.
Damage to a brick building. Earthquake-strengthening ties have prevented the gable end from collapsing, but large cracks are still visible.

A house perched on the edge of the cliff above Sumner. Below, large bolts have been inserted into the cliff face above a cave entrance to strengthen it.
The brick chimney section of a house on Avonside Drive. Cracks can be seen between the bricks and the whole chimney has moved away from the rest of the house. It has been strengthened with timber bracing.
The upper section of the Durham Street Methodist Church. Scaffolding has been constructed to allow workers from the South Island Organ Company to retrieve the church's valuable and historic organ. The windows at the far end have been weather proofed with plywood and strengthened with timber bracing.
The ruins of the historic Durham Street Methodist Church in the aftermath of the 22 February 2011 earthquake. The only parts of the building still upright are those supported by steel braces placed there after the 4 September 2010 earthquake to strengthen the building as it awaited repairs. Rubble has spilled out onto the street, knocking over the safety fences that were also erected after September. Silt from liquefaction has covered the road around the church.
