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.
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.

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.
