Model: Liquefaction Volcano
Images, Canterbury Museum
Plastic and wood model of three liquefaction volcanoes. The working model pumps water over the grey surface which is decorated with a basket of laundry, a bucket of pegs and a football. The model is surrounded by artificial green grass and rests atop a black wooden base.
Grass and Liquefaction
Images, UC QuakeStudies
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".
It is the Way You Look at It
Images, UC QuakeStudies
A 'sand volcano' of liquefaction silt. The photograph has been rotated 180 degrees. The photographer comments, "This could be just a horrible hole caused by liquefaction pouring out of a hole after the Christchurch earthquake in January, but turn it upside down and it becomes an outcrop on the floor of an unseen tidal estuary".

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).
Safe Dust
Images, UC QuakeStudies
A digitally manipulated image of printer's type, spelling out "Safe Dust". The photographer comments, "After the September 2010 Christchurch earthquake liquefaction poured out of the ground mostly in the East of Christchurch. This silt, which was a form of sand was declared safe and would not harm gardens if it was spread around in moderation. After the February 2011 quake as a result of even more liquefaction and the sewers being ruptured, the liquefaction was declared as toxic. People clearing it up should wear a mask, boots and gloves especially when it had dried up and become dusty. This just so happens to be the words found on an old printing press".

The Drunken Lampposts
Images, UC QuakeStudies
A residential street in New Brighton. Liquefaction still lines the street, and lampposts are leaning in different directions. The photographer comments, "This is the New Brighton red zone, which is parallel to the Avon River. The area suffered serious liquefaction during the numerous earthquakes/aftershocks and the land is being bought by the government. Although the houses do not look too bad in the background they have suffered badly. On the day I took this picture the council had just hours before cut the grass, which made the area look less abandoned".
You Know the Drill
Images, UC QuakeStudies
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".
Nisbet, Alistair, 1958- :'Course it's safe to rebuild...' 7 January 2012
Images, Alexander Turnbull Library
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).
Nisbet, Alistair, 1958- :The REAL Christchurch buskers... 19 January 2012
Images, Alexander Turnbull Library
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. Quantity: 1 digital cartoon(s).
This is an Earthquake Not a Wide Angle Shot
Images, UC QuakeStudies
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".
Terra Probe
Images, UC QuakeStudies
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".
What Happens When You Have a Saggy Bottom
Images, UC QuakeStudies
A fence along the side of the Avon River near the Retour Restaurant has broken and is leaning towards the river. The photographer comments, "After the Christchurch earthquakes the land moved towards the river Avon and in a lot of places buildings and walls sagged down in the direction of the waterway".
Sagging in the Middle
Images, UC QuakeStudies
A wooden house in Wainoni has visibly bowed inwards towards its centre. The photographer comments, "During the numerous earthquakes in Christchurch the land which ran alongside the Avon river on Avonside Drive slumped towards the waterway. In a line parallel to the road the road, but around 20m away a ground movement occurred which caused some houses to rise up or sink down".
2011 Festival of Flowers
Images, UC QuakeStudies
A laminated sign for the 2011 Festival of Flowers attached to a wooden planter. The plants in the planter are dry and dead. The photographer comments, "The theme for the 2011 Festival of Flowers was 'burst! of water'. The Christchurch February earthquake came and water and sand called liquefaction burst out of the ground all around the area. Ironically the plants for the festival were left unattended in the cordoned off red zone and they would have loved a little burst of water".
Cracks in the Veneer
Images, UC QuakeStudies
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".
