Road damage and liquefaction in a residential street. The photographer comments, "A great gouge in the road caused by liquefaction undermining the road surface and a car driving over it. This was the earthquake in Christchurch, New Zealand on 22 February 2011".
This study analysed liquefaction susceptibility and estimated ground settlements for two earthquake scenarios (foothills and Alpine Fault) for eastern Waimakariri District. The report was later partially superseded by Earthquake hazard assessment for Waimakariri District (Yetton and McCahon, 2009), which while not using such detailed analytical methods as the 2000 Beca report, reviewed new information available since 2000 (including that collected as part of the Pegasus Town development). This showed that the liquefaction susceptibility in eastern Waimakariri district was in fact much more variable than suggested in the 2000 Beca maps, and that liquefaction susceptibility was extremely difficult to predict without a site-specific investigation. See Object Overview for background and usage information.

A pile of liquefaction silt in Parklands has been decorated with a Santa hat, Christmas decorations and a pair of jandals to form a silt 'snowman'. The photographer comments, "Not the most welcome Santa to find on your doorstep on Xmas Eve. This was made out of damp liquefaction in Parklands".
A large pile of liquefaction silt in Parklands has been topped with a Christmas star. The photographer comments, "Not exactly the kind of sand castle you want to build on your Summer holidays. This is the biggest of several piles of liquefaction in just one street in Parklands/Queenspark".
