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 "sand volcano" of liquefaction silt.
A typical "sand volcano" 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.

A sand volcano in the Halswell Primary School grounds. 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.
Large cracks in the playing field in Porrit Park are surrounded by "volcanoes" of liquefaction silt.

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.

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.
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.
