A photograph of the earthquake damage to the Observatory tower at the Christchurch Arts Centre. The top two storeys of the tower collapsed during the 22 February 2011 earthquake and the rubble spilled into the courtyard in front. A digger was used to clear the rubble away from the building. A tarpaulin has been draped over the top of the broken tower and the roof behind.

Two images of a house, taken before and after the earthquakes. In the after photograph the chimneys are gone, a column supporting the car port has partly collapsed, windows are broken, and the previously neat lawn and driveway are overgrown. The photographer comments, "This was a house that I was selling up to the September 2010 earthquake in Christchurch. It was on Avonside Drive, which was an area that has been badly hit in every earthquake that has hit the area. In the September quake parts of the house moved in different directions and one of the upstairs doors had to be smashed open to release one of the sons from his bedroom. This occurred in the dark with numerous aftershocks shaking the house. Liquefaction poured up through the floor and flowed down the drive. Everyone got out OK, but soon after the house was red stickered meaning it was dangerous to enter. The house was looted many times even though there was constant police patrols. When the most violent earthquake occurred on 22 February 2012 both the tall heavy chimneys came crashing through into the living areas. Subsequent earthquakes and aftershocks have caused one of the brick fence pillars to fall and the front garage pillar to break up and twist. The family's troubles did not end there. They moved into the home of one of their parents and this mansion of a home was so badly affected by the February earthquake that no one could enter to collect any of their or their parents' belongings. They now own a new home, which they are fond of except when the ground shakes yet again. There has been to date 10,712 earthquakes and aftershocks since 4 September 2010".

Two skeletal people sit in armchairs waist-deep in silt. The man is reading the newspaper and says 'The wait's over! The Land Report's due out dear!... DEAR?' He realises that his wife, whose bony hand clutches 'EQC update No. 37', is dead. Context - On Thursday 23 June Prime Minister John Key, Canterbury Earthquake Recovery Minister Gerry Brownlee and representatives from engineering consultants Tonkin & Taylor announced the first part of the Government's long-awaited land report that revealed the fate of up to 5000 quake-damaged homes.

Damage to TJ's Kazbah in New Brighton. The east and north walls and part of the upper floor have collapsed, tipping rubble and the contents of the rooms out onto the street. The photographer comments, "The occupants of the business and rooms all managed to escape alive. A digger was used to make the building safe and then used to sift through the rubble for any surviving belongings. It was a very emotional time for the ex-occupants".

The 22 February 2011, Mw6.2-6.3 Christchurch earthquake is the most costly earthquake to affect New Zealand, causing 181 fatalities and severely damaging thousands of residential and commercial buildings, and most of the city lifelines and infrastructure. This manuscript presents an overview of observed geotechnical aspects of this earthquake as well as some of the completed and on-going research investigations. A unique aspect, which is particularly emphasized, is the severity and spatial extent of liquefaction occurring in native soils. Overall, both the spatial extent and severity of liquefaction in the city was greater than in the preceding 4th September 2010 Darfield earthquake, including numerous areas that liquefied in both events. Liquefaction and lateral spreading, variable over both large and short spatial scales, affected commercial structures in the Central Business District (CBD) in a variety of ways including: total and differential settlements and tilting; punching settlements of structures with shallow foundations; differential movements of components of complex structures; and interaction of adjacent structures via common foundation soils. Liquefaction was most severe in residential areas located to the east of the CBD as a result of stronger ground shaking due to the proximity to the causative fault, a high water table approximately 1m from the surface, and soils with composition and states of high susceptibility and potential for liquefaction. Total and differential settlements, and lateral movements, due to liquefaction and lateral spreading is estimated to have severely compromised 15,000 residential structures, the majority of which otherwise sustained only minor to moderate damage directly due to inertial loading from ground shaking. Liquefaction also had a profound effect on lifelines and other infrastructure, particularly bridge structures, and underground services. Minor damage was also observed at flood stop banks to the north of the city, which were more severely impacted in the 4th September 2010 Darfield earthquake. Due to the large high-frequency ground motion in the Port hills numerous rock falls and landslides also occurred, resulting in several fatalities and rendering some residential areas uninhabitable.

A woman walks through the snow in Christchurch and comments 'At least snow covers up ugly quake damage dear... Dear?' Her husband has disappeared into a hole that was covered in snow. Context: Heavy snow blanketed Christchurch today (Saturday 9 August) as the winter cold continued to be felt across both the North and South Islands.

Broken panelling on a building on Colombo Street has exposed the interior of the walls. The photographer comments, "Seen in the Christchurch Earthquake Red Zone. If you saw this anywhere else in the world you would have thought that it was a piece of modern art".

Text at top left reads 'Christchurch display portaloos' Four different styles of portaloo are shown; the "Merivale", the 'Sumner", the "Heritage" and the "Eastsider"; someone inside the 'Eastsider says 'At least I'm open plan AND mobile!' Context - After the tow Christchurch earthquakes and hundreds of aftershocks that have hit Christchurch one of the problems is lack of toilets because of damage to buildings and also damage to sewage systems so many portaloos and chemical toilets have been sent to Christchurch. However many people have resorted to the good old kiwi way and dug long-drops in the backyard. A website 'showusyourlongdrop.co.nz' has been developed by Christchurch man Jason Moore, who was inspired by photographs of Christchurch dunnies uploaded to Facebook. There has been a competition.

Context - the fragility of the world from a New Zealand point of view seen in the light of the Christchurch earthquakes of 4 September 2010 and 22 February 2011 and the Japanese earthquake and tsunami of 22 February 2011 and the present threat of a nuclear catastrophe caused by damaged nuclear power plants.

The partially-demolished Henry Africa's building. The photographer comments, "A building housing a restaurant and a great little neighbourhood bar is finally coming down because of earthquake damage. Fenced off for safety. People who regularly use Stanmore Rd will be happy when the demolition is complete".
