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 The report was later partially superseded by Earthquake hazard assessment for Waimakariri District (Yetton and McCahon, 2009), which while not using such detailed analytical methods as the 2000 Beca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.
The Christchurch liquefaction study was initiated to better determine liquefaction susceptibility in Christchurch city. It aimed to improve on earlier liquefaction susceptibility maps, which were based on soil type and distribution, by incorporating soil strength data into liquefaction analysis. This stage of the study included collating available geological and geotechnical data from Environment Canterbury and Christchurch City Council into a database, modelling liquefaction hazard and ground damage and presenting these as maps. The report contains many recommendations, which were taken up in subsequent stages of the study. (Note that the results of Stage 1 of the Christchurch liquefaction study were provided to Environment Canterbury as a letter rather than a report. This was a summary of work completed to 30 June 2001, including a review of geological and geotechnical data available within Environment Canterbury and Christchurch City Council records.) See Object Overview for background and usage information.
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.
Stage IV of the Christchurch liquefaction study updated the Stage II liquefaction hazard and ground damage maps with further data collected from other organisations, and included two additional maps indicating liquefaction sensitivity to groundwater levels. Stage IVa of the Christchurch liquefaction study used revised groundwater levels and adjustments to the liquefaction prediction algorithm. The outputs of the report were liquefaction hazard and ground damage maps for both average summer (low) and average winter (high) groundwater levels. The maps produced as part of Stage IVa of the report were subsequently included in an Environment Canterbury public education poster The Solid Facts on Christchurch Liquefaction which also contained information on how liquefaction occurs and what can be done to mitigate the liquefaction hazard. Stage IV of the Christchurch liquefaction study contained a number of recommendations to improve the liquefaction potential and ground damage maps for Christchurch.
