A sand volcano in the Halswell Primary School grounds near the playground. 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.
The road and footpath in a residential area are lined with piles of silt from liquefaction. A portaloo stands at the front of a house.
A portaloo outside the Christchurch branch of Deaf Aotearoa. Dried silt from liquefaction can be seen along the footpath and the edge of the building.
Bricks from a demolished chimney lie on top of thick liquefaction silt in front of a house in St Albans. The photographer comments, "Our friend Chris Hutching's house. The front lawn and carport have 30cm or more of silt piled on top. He also had to remove a shaky chimney".

A large hole surrounded by liquefaction silt in the garden of a house in Bexley. The photographer comments, "This was most probably the serious hole I saw today. Can you imagine that when this occurred the whole area would have been inches deep in brown water. You would not been able to tell what you were walking on. Back in February a little girl rode her bike into one of these and had to be rescued by a passer by".
Large piles of liquefaction silt at a dump on Breezes Road. One of the piles is covered with black plastic and weighted down with tyres. Trucks and diggers are adding more silt to the piles. The photographer comments, "Breezes Road and Anzac Drive have recently opened but are now home to a brand new range of hills thanks to mountains of silt that have been collected by the hard working construction guys that have done a sterling job on the road there".

A photograph of a portaloo outside a residential property in Christchurch. After the 22 February 2011 earthquake, many houses had no running water and were forced to use chemical toilets or portaloos placed along the street. There is flooding and liquefaction on the street in the foreground. Liquefaction silt has been piled on the side of the road and a road cone placed in front.
Workers use a large water-blasting pipe to clear blocked drains. The photographer comments, "The Australian company Barry Bros Turned up very late at night to clean out our street drains of liquefaction".

Liquefaction and buckled tarmac on a residential street in North New Brighton. The photographer comments, "In the February 2011 earthquake in Christchurch the kerb at the end of my road was pushed from both ends. This caused it to move away from the grass verge and push itself under the tarmac. The tarmac would normally have been 3 inches below the top of the kerb. Between the kerb and the grass can be seen the colour of the liquefaction that spewed out from the ground. The tarmac in the area seemed to flow downhill".
