Extensive damage caused by liquefaction in Bracken Street, Avonside. A pile of liquefaction can be seen in front of this house. After the earthquake, many people had to dig this silt out of their properties and place it on the road to be collected.
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 The report was later partially superseded by Earthquake hazard assessment for Waimakariri District (Yetton and McCahon, 2009), which while not using such detailed analytical methods as the 2000 Beca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 long line of cars on Shirley Road. While the centre of the road is clear, there is flooding and liquefaction along the edges.

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".
A digger scrapes up liquefaction silt from Warden Street in Shirley, while workers with shovels look on. The photographer comments, "Clearing silt in Warden St".

A typical "sand volcano" 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 car mired in liquefaction in a car park on Chester Street in the aftermath of the 22 February earthquake. Behind it, the collapsed Durham Street Methodist Church can be seen.
This study determined areas of different liquefaction susceptibility in Hurunui District based mainly on geological data, with some limited borehole strata interpretation. Geotechnical data was not analysed. This was the same method used in the earthquake hazard assessments for engineering lifelines in other districts in Canterbury. Hurunui District was the first district that a hazard assessment for engineering lifelines was undertaken for (in 2000) and it did not include a liquefaction susceptibility map like the other district earthquake hazard assessments did. There are no recommendations associated with this report. See Object Overview for background and usage information.
