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 '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 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".

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".

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 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 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".

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".

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".

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".

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".
