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".

Workers inspect a broken sewerage line in New Brighton. The photographer comments, "After the Christchurch earthquake on 23 December 2011 the sewer pipe got badly damaged at New Brighton and was leaking into the Avon River. I think the guy was worried about the fast flow causing him to fill his boots rather than the depth".

Liquefaction in North New Brighton. The photographer comments, "This was the liquefaction pouring out of a split in the road where it joins the side-walk. The quakes felt pretty violent, but the damage was less severe than the February one. Unlucky for me the epicentre was only 9.6km away and smaller aftershocks were a lot closer".
