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".

A 'sand volcano' of liquefaction silt in Bexley. The photographer comments, "Liquefaction is just a mixture of sand and water squeezed up from the ground, but with a little imagination it has a beauty in its untouched state".
