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 volcano of liquefaction silt outside McDonald Hartshorne on Manchester Street.

Mini silt volcanoes in their back yard.
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.

Sand volcanoes put the silt all over the road.
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.

Liquefaction 'volcanos' in Kaiapoi, after the September 4th earthquake. Silt erupted out of the ground, piling up over the surface and leaving cracks at the mouth of the volcano.

It would have been a glorious Spring day in Christchurch had it not been for the magnitude 7.1 earthquake at 4:30 am.
All the water and silt you can see covering the street in this photo erupted from the ground following the earthquake.
A misaligned brick wall in front of a property with silt still piled up around it. During the earthquake, liquefaction drove silt to the surface where it erupted out of the ground like a volcano and formed a pile like the one seen here.
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".
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. 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".
