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.

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.
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.

This has made a huge mess for the residents to clean up. I heard on the news that homes have been damaged by subsidence in areas of earthquake-caused liquefaction like this.
A 'sand volcano' of liquefaction in a crack in a gravel driveway beside a house in Richmond. The photographer comments, "Liquefaction in back yard".
Liquefaction silt and sand cover the lawn of a residential property. The photographer comments, "This is a garden inundated with liquefaction. Though most liquefaction is grey in Christchurch there must have been golden sandy beaches before the volcanoes erupted millions of years ago".
This one was really flowing out of the ground.
