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.
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 box containing drilling cores from soil sampling. The photographer comments, "These are the samples from drilling near my home. As you can see they are not so much samples as sand piles. The drill in a nearby street went down 20m and it was sand all the way. This is the box of samples from the ground level to 4.6m deep".
