8 Velsheda Street, Bexley, Christchurch, across the road from my house was demolished a week or so ago, just one of many demolitions of Red Zone properties at the moment. This house was about ten years old and suffered land damage during the 4th September 2010 and 22nd February 2011 earthquakes. The same fate awaits my house later in the year o...

Large cracks run through the brick cladding of this house in Wainoni. The photographer comments, "During the numerous earthquakes in Christchurch the land which ran alongside the Avon river on Avonside Drive slumped towards the waterway. Houses which were wooden framed and had an external brick veneer started to sink into the liquefied soil. This caused the brick walls to crack, but the houses' occupants though shook up were saved by the wooden framework from the houses collapsing on them".
A badly damaged house in Burwood. Parts of the house have moved in different directions, leaving walls and doors misaligned. The photographer comments, "Although this looks like an extreme wide angle shot it is actually a house tilted in every direction at the same time. The earthquake caused the ground to vibrate and compress so much that the sandy soil liquefied and caused the ground to collapse under this modern home".
Shows rain falling over two gondolas of people floating past flooded Christchurch damaged houses. One person points to people in balaclavas climbing over the houses and calls out 'And look...the wildlife's returning!'. Context: Heavy rain and flooding hit Christchurch suburbs, including earthquake damaged homes (Newstalk website 14 August 2012). At the same time, wildlife (possums and rare birds) are moving into abandoned suburbs (Stuff 13 August 2012) Quantity: 1 digital cartoon(s).

A digitally manipulated image of a broken window on Spicer House. The photographer comments, "One of the office blocks in Christchurch City, New Zealand. As the window has not been fixed I am presuming that this building will be slowly demolished at a later date".

A damaged chimney on the roof of a house in Kaiapoi. The bricks have crumbled onto the roof where they lie precariously. These will have to be removed and the rest of the chimney deconstructed by hand.
Part of Mike Hewson's installation 'Homage To Lost Spaces' in the Cramner Courts building, a photograph of a skateboarder has been inserted into a gap in the building. The photographer comments, "Although Cranmer Courts are in ruins pictures have been inserted into the windows to make them look more 'normal'".

A member of the public takes a closer look into the cordon, looking down to Hereford Street to the damaged Gough House, with windows boarded up and part of the Vintage Watch store. On the fence is a sign that says 'Road closed' and another one advertising a Wilson's carpark.
A man and a woman wearily face one another wondering how they should celebrate two years of frustration. Context: relates to continuing frustration over lack of progress by many people whose houses have been damaged in the Christchurch earthquakes. Quantity: 1 digital cartoon(s).
one of Christchurch's abandoned suburbs. The land moved - bricks and block walls everywhere collapsed - two multi story buildings folded - 184 people died. Wooden framed houses largely stayed up, many concrete slabs cracked, power poles leaned in liquid ground, surface bubbled, services ruptured .... damage to the cbd still gets the most cover...
Shows three new houses sinking into liquefaction after another series of strong aftershocks in early January. A sign reads 'Parklands' and an observer confidently asserts that it is safe to rebuild. Context: the suburb of Parklands in north east Christchurch has been badly damaged by liquifaction. Quantity: 1 digital cartoon(s).
A digitally manipulated image of the Gap Filler Monopoly board square on Manchester Street. The photographer comments, "On the site of a demolished earthquake damaged building in Christchurch, New Zealand is a Monopoly game square for giants. The Gap Filler Project makes the bare land where once a building once stood into something both interesting and unique and this time they created a massive Monopoly board square. In the game of Monopoly you move your player with a dog, shoe or maybe the hat, but as the most common thing in the City are diggers they have the placed one on the square. There are also two houses on Manchester Street, which is priced at $240".
In the period between September 2010 and December 2011, Christchurch (New Zealand) and its surroundings were hit by a series of strong earthquakes including six significant events, all generated by local faults in proximity to the city: 4 September 2010 (Mw=7.1), 22 February 2011 (Mw=6.2), 13 June 2011 (Mw=5.3 and Mw=6.0) and 23 December 2011 (M=5.8 and (M=5.9) earthquakes. As shown in Figure 1, the causative faults of the earthquakes were very close to or within the city boundaries thus generating very strong ground motions and causing tremendous damage throughout the city. Christchurch is shown as a lighter colour area, and its Central Business District (CBD) is marked with a white square area in the figure. Note that the sequence of earthquakes started to the west of the city and then propagated to the south, south-east and east of the city through a set of separate but apparently interacting faults. Because of their strength and proximity to the city, the earthquakes caused tremendous physical damage and impacts on the people, natural and built environments of Christchurch. The 22 February 2011 earthquake was particularly devastating. The ground motions generated by this earthquake were intense and in many parts of Christchurch substantially above the ground motions used to design the buildings in Christchurch. The earthquake caused 182 fatalities, collapse of two multi-storey reinforced concrete buildings, collapse or partial collapse of many unreinforced masonry structures including the historic Christchurch Cathedral. The Central Business District (CBD) of Christchurch, which is the central heart of the city just east of Hagley Park, was practically lost with majority of its 3,000 buildings being damaged beyond repair. Widespread liquefaction in the suburbs of Christchurch, as well as rock falls and slope/cliff instabilities in the Port Hills affected tens of thousands of residential buildings and properties, and shattered the lifelines and infrastructure over approximately one third of the city area. The total economic loss caused by the 2010-2011 Christchurch earthquakes is currently estimated to be in the range between 25 and 30 billion NZ dollars (or 15% to 18% of New Zealand’s GDP). After each major earthquake, comprehensive field investigations and inspections were conducted to document the liquefaction-induced land damage, lateral spreading displacements and their impacts on buildings and infrastructure. In addition, the ground motions produced by the earthquakes were recorded by approximately 15 strong motion stations within (close to) the city boundaries providing and impressive wealth of data, records and observations of the performance of ground and various types of structures during this unusual sequence of strong local earthquakes affecting a city. This paper discusses the liquefaction in residential areas and focuses on its impacts on dwellings (residential houses) and potable water system in the Christchurch suburbs. The ground conditions of Christchurch including the depositional history of soils, their composition, age and groundwater regime are first discussed. Detailed liquefaction maps illustrating the extent and severity of liquefaction across Christchurch triggered by the sequence of earthquakes including multiple episodes of severe re-liquefaction are next presented. Characteristic liquefaction-induced damage to residential houses is then described focussing on the performance of typical house foundations in areas affected by liquefaction. Liquefaction impacts on the potable water system of Christchurch is also briefly summarized including correlation between the damage to the system, liquefaction severity, and the performance of different pipe materials. Finally, the characteristics of Christchurch liquefaction and its impacts on built environment are discussed in relation to the liquefaction-induced damage in Japan during the 11 March 2011 Great East Japan Earthquake.
