Liquefaction Studies (ECan)

The Waimakariri and Christchurch liquefaction studies (2000-2005), are Environment Canterbury’s most detailed analyses of liquefaction susceptibility. See Collection Overview for background and usage information.

Christchurch Liquefaction Study: Stage II
Christchurch Liquefaction Study: Stage II
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.)

Christchurch liquefaction study: Stage IV
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.

Liquefaction hazard in Hurunui District
Liquefaction hazard in Hurunui District
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.

Liquefaction study Waimakariri District
Liquefaction study Waimakariri District
This study analysed liquefaction susceptibility and estimated ground settlements for two earthquake scenarios (foothills and Alpine Fault) for eastern Waimakariri District. See the Object Overview for background and usage information.
