Workers operate a drilling rig, sampling soil as part of EQC's geotechnical investigation of TC3 land. The photographer comments, "The work of getting 'soil' samples from all the areas marked as green/blue zones in Christchurch. These areas may be susceptible to liquefaction if a major earthquake occurs. The soil samples were a failure as all they found was sand".
A map of Christchurch soils.
A photograph of volunteers digging soil to construct a BMX track.
Flowers planted in an upside-down road cone embedded in the soil.
A digger works on top of a pile of soil and building rubble.
As the tanks were empty, they floated due to soil liquefaction. Pages Road.
A photograph of a truck delivering soil for a beach garden in New Brighton.
Grass growing through liquefaction silt in Avondale. The photographer comments, "Although this grass seems to be growing on the liquefaction created by the earthquakes in Christchurch, New Zealand, they are actually only growing through it. Nothing seems to grow even though seeds will sprout almost anywhere else. The seeds are growing in the soil which got covered up by the liquefaction. If liquefaction gets mixed with even a little soil then nature can get a foothold".
A box containing drilling cores from soil sampling. The photographer comments, "These are the samples from drilling near my home. As you can see they are not so much samples as sand piles. The drill in a nearby street went down 20m and it was sand all the way. This is the box of samples from the ground level to 4.6m deep".
Photograph captioned by Fairfax, "Demolition underway on the Manchester Courts Building. Street sign dwarfed by the large mound of soil alongside the building".
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".
A contractor with a roller stands in an enormous hole, and shouts up to a family standing at the top that it's now ready to be built on. Refers to efforts to compact soil in Christchurch to prevent further liquefaction following the Canterbury earthquakes. Quantity: 1 digital cartoon(s).
The head of a digger resting on a pile of soil next to QEII Stadium. The photographer comments, "The deconstruction of the QEII stadium in Christchurch pauses on a Sunday".
A digitally manipulated image of the head of a digger resting on a pile of soil. The photographer comments, "You can go anywhere you like when you are a rock star".
A silt castle has been built by Christchurch East that wins the competition. Context: The eastern suburbs have had a lot of problems with liquefaction following earthquakes and aftershocks. Quantity: 1 digital cartoon(s).
The cartoon shows two images of cars nose-down in ditches, the first is caused by 'liquifaction' and the second by 'stupifaction'. Context: there was another large aftershock on Boxing Day in Christchurch which resulted in quite a lot of liquefaction. There is always concern over the Christmas holidays about drinking while driving. Other Titles - Liquefaction Quantity: 1 digital cartoon(s).
A very large woman stands wedged between two rows of concrete pillars eating a huge cream bun. She says 'Christmas fare protection... it helps prevent lateral spread!' Context - overeating at Christmas and lateral spreading, which is associated with liquefaction and tends to occur near streams and waterways as the soil mass moves towards them. Reference to the Christchurch earthquake of 4th September 2010. Quantity: 1 digital cartoon(s).
A small boy is being a real entrepreneur after the Christchurch earthquake of 22 February 2011 and has set up a road-side stall from which you can buy a bag of 'real leakyfakshun'. Behind him is a pile of liquefaction and a spade with which he can fill bags. Context - the Christchurch earthquake of 22 February has caused vastly more liquefaction than the original 4th September earthquake. The vibrations from the quake cause liquefaction which is where the soil loses strength and stiffness, and behaves more like a liquid than a solid - rather like wet sand. Colour and black and white versions available Quantity: 2 digital cartoon(s).
Workers operate a drilling rig inside a Terra Probe truck, which has been raised on jacks to make it stable. The photographer comments, "Another completely different company testing what is below the surface to determine what type of foundations new houses will need. This is in one the blue/green area of earthquake shaken Christchurch. Strangely this is 3 metres away from where the other testing was done".
Text reads 'Latest Christchurch East band' The name of the band is 'The Silty Stones' and the band sings 'We can't get no... sa-tis-faction! 'Cos we got more li-qui-faction! And we cry, and we cry, and we try to get by We can't get no sa-tis-faction!' The band are cleaning up the latest liquefaction from around a house and are using their tools as musical instruments. Context: there was a 4.9 magnitude aftershock in Canterbury on December 26th (Boxing Day 2011) The song is a take-off of the 'Rolling Stones' song 'We can't get no satisfaction'. Quantity: 1 digital cartoon(s).
The Earthquake Commission calls a householder and tells him the 'good news' that his house which was left by the earthquakes in 'such an angle you couldn't live in it' has been refloated by the recent heavy rain and is now level again. The 'bad news' is that the house was last seen floating in the sea off Sumner. In June 2013 heavy rains had caused flooding in Canterbury. Christchurch was affected especially in the liquefaction prone areas, where the ground had sunk because of the earthquakes.

A two-storey house in Avonside Drive with a warped upper balcony. The photographer comments, "This house is on Avonside Drive opposite the Avon River. The land in this area spread laterally and had bad liquefaction of the soil. This caused some houses to sink into the ground, but as the balcony supports did not sink as much the balcony came to rest at a crazy angle".
A digitally manipulated photograph of twisted reinforcing rods amongst the rubble from the demolition of QEII. The photographer comments, "These rarely seen worms live in the pressurised earth under the foundations of buildings. They need a damp soil and be under at least 100 pounds of pressure per square inch. After the destructive force of an earthquake they swiftly rise to the surface through gaps in the rubble. Unfortunately they quickly die and then crystallise as hard as iron in the dry low pressure air".
Text reads 'The new liquefaction?...' and the cartoon depicts a huge mass of 'insurance red tape' inside which is a man with a spade. Two people stare despairingly at the red tape and the man says 'How are we EVER gonna rebuild with this stuff bubbling up!' Context: The people are trying to rebuild their house after the Christchurch earthquakes and are having trouble with their insurance company. The Press has been contacted by people unable to get insurance to buy new homes, construct buildings or start businesses. Business leaders have called insurance delays a "cancer" eating away at the city's recovery, and Earthquake Recovery Minister Gerry Brownlee has acknowledged insurance is an "ongoing problem". (The Press - 24 August 2011) Quantity: 1 digital cartoon(s).
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".
Aspects of Christchurch life after the earthquakes of 2010 and 2011, modelled on acts performed at the Buskers' Festival being held in Christchurch. Include `Silt walking'through liquefaction; 'Orange zone', representing the paralysis of homeowners whose properties were classified as 'orange', or of undecided status; 'Jugglers "Marryatt" and "Red Zone"': the Christchurch CEO, Tony Marryatt, juggles with money, his large pay rise, while the red-zoned householder juggles with unattractive options; 'The boy [CBD] with red tape all over him', referring to the cordon which was strangling the Central Business District; the columnist Joe Bennett with his dog, refusing to move from his house in Lyttelton, a cause celebre of resistance to the earthquake authorities in those days.
