Dried liquefaction silt in North New Brighton. The photographer comments, "This is the result of liquefaction which spewed out after the double earthquake in Christchurch. Having flowed into a shallow depression that was deep enough for a fair quantity of the silty liquid to settle and separate: the heavy sand below and a talcum powder like substance on top. Some of these are so delicate that a mouse crossing them would probably crack them. Here the sun has dried them out and they have contracted and curled up towards their centres".

Dried liquefaction silt in North New Brighton. The photographer comments, "This is the the top layer of liquefaction that has dried up in the hot sun. A broken eggshell is around 5 times stronger than these, but a fallen leaf is just not enough to break one. You can see underneath that the heavier sandy layer of liquefaction has dried and has cracked as well".

A small boy is being a real entrepreneur after the Christchurch earthquake of 22 February 2011 and has set up a road-side stall from which you can buy a bag of 'real leakyfakshun'. Behind him is a pile of liquefaction and a spade with which he can fill bags. Context - the Christchurch earthquake of 22 February has caused vastly more liquefaction than the original 4th September earthquake. The vibrations from the quake cause liquefaction which is where the soil loses strength and stiffness, and behaves more like a liquid than a solid - rather like wet sand.
