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".

A 'sand volcano' of liquefaction silt. The photograph has been rotated 180 degrees. The photographer comments, "This could be just a horrible hole caused by liquefaction pouring out of a hole after the Christchurch earthquake in January, but turn it upside down and it becomes an outcrop on the floor of an unseen tidal estuary".
