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 photograph of a silt volcano. Silt volcanoes are caused by liquefaction, when the soil loses its strength during the earthquake and the silt rises upwards, ejecting out of a hole like magma in a volcano.
As the tanks were empty, they floated due to soil liquefaction. Pages Road.
A photograph of a crack in the pavement of a residential street in Christchurch. The crack was caused by liquefaction erupting out of the soil underneath.
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".
Sand volcanoes" in the Heathcote Estuary. The volcanoes were caused by liquefaction, where the soil lost its strength and water erupted out of the hole, taking silt with it.

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.

Paradise ducks search for food among 'sand volcanoes' in the Heathcote Estuary. The volcanoes were caused by liquefaction where the soil lost its strength and water erupted out of the hole, taking silt with it.
People walking amongst silt in Hagley Park shortly after the 22 February 2011 earthquake. These silt deposits were caused by the soil liquefying during the 22 February 2011 earthquake. The water flowed out, bringing sand with it.

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.

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.

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.

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 sand volcano in the Halswell Primary School grounds. Sand volcanoes were caused by liquefaction where the soil loses its strength during the earthquake and the silt rises upwards, ejecting out of a hole like magma in a volcano.
