Grass growing through liquefaction silt in Avondale. The photographer comments, "Although this grass seems to be growing on the liquefaction created by the earthquakes in Christchurch, New Zealand, they are actually only growing through it. Nothing seems to grow even though seeds will sprout almost anywhere else. The seeds are growing in the soil which got covered up by the liquefaction. If liquefaction gets mixed with even a little soil then nature can get a foothold".

A digitally manipulated photograph of the bottom of Victoria Lake in Hagley Park. The photographer comments, "After the Christchurch earthquake in February 2011, Victoria Lake suffered some cracking which broke the previous clay seal. The lake has now been excavated so that the new clay seal can be spread out and flattened ready to be filled again with water. The red pile is the clay and in the background is the grey silt or liquefaction that spewed into the lake from cracks in the lake bed".
