dc.title: General distribution and characteristics of active faults and folds in the Ashburton District, mid-Canterbury
dc.description: This report provides information on the locations and character of active geological faults and folds in Ashburton District. The faults are mapped at a district scale and the information is intended to highlight areas where there is a risk of permanent fault movement at the ground surface, and where more detailed investigations should be done if development is proposed in that area (depending on the potential activity of the fault and the type of development proposed). See Object Overview for background and usage information. Most of the faults and folds identified at the ground surface in Ashburton District are in rural or very sparsely populated areas. In addition, most of the faults have relatively long recurrence intervals (long-term average time between fault movements) in the order of several thousand years. Following the Ministry for the Environment Active Fault Guidelines, normal residential development would be allowed on or near faults with recurrence intervals this long. There are no recommendations associated with this report. The information in the report will be reviewed as required, after the remaining district reports are completed in the region.

dc.title: Earthquake Hazard Assessment for Kaikoura District
dc.description: This report describes the earthquake hazard in Kaikoura district and gives details of historic earthquakes. It includes district-scale (1:250,000) active fault, ground shaking zone, liquefaction and landslide susceptibility maps. The report describes an earthquake scenario for a magnitude 7.0-7.3 Hope Fault earthquake near Kaikoura, and a subsequent local tsunami.

dc.title: Christchurch Liquefaction Study: Stage II
dc.description: 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.)

dc.title: Greendale Fault: investigation of surface rupture characteristics for fault avoidance zonation
dc.description: The previously unknown Greendale Fault ruptured to the ground surface, causing up to 5 metres horizontal and 1 metre vertical permanent offset of the ground, during the September 2010 Darfield (Canterbury) earthquake. Environment Canterbury commissioned GNS Science, with help from the University of Canterbury, to define a fault avoidance zone and to estimate the fault recurrence interval. There is little evidence for past movement on the fault in the past 16,000 years. However, because of the uncertainties involved, a conservative approach was taken and the fault has been categorised as a Recurrence Interval Class IV fault (a recurrence interval of between 5,000 and 10,000 years). A PhD study by a University of Canterbury student will work towards refining the Recurrence Interval Class over the next three years. Taking a risk-based approach, the Ministry for the Environment Active Fault Guidelines recommend that normal residential development be allowed within the fault avoidance zone for faults of this Recurrence Interval Class, but recommends restrictions for larger community buildings or facilities with post-disaster functions. The report is assisting Selwyn District Council in granting consents for rebuilding houses on or near the Greendale Fault that were damaged by permanent distortion of the ground due to the fault rupture in the September 2010 earthquake. The report provides specific recommendations for building on or close to the Greendale Fault, which are being implemented by Selwyn District Council. See Object Overview for background and usage information.
