Ashley Fault Zone Fault Complexity 2014
Environment CanterburyThere are four maindata fields. 'AREA' gives the extent of each polygon in square metres. 'Feature' identifies the fault deformation hazard/Fault Avoidance Zonation unit type, based largely on the 'TYPE' field in the Ashley Fault Zone ground deformation dataset. 'FAZ_class' identifies the category of fault complexity, as set out in Table 2 of...Created 9 March 2021 • Updated 14 April 2021 -

Ashley Fault Zone Landform Feature Lines 2014
Environment CanterburyThere are two main data fields. 'ACCURACY' identifies the basis on which the line was mapped; 'schematic' (where the landform feature is sharply defined in a topographic sense, and thus the line denotes the general presence of a feature, not an exact location) and 'approx-lidar' (the feature is identifiable topographically in lidar data, but it is not...Created 9 March 2021 • Updated 14 April 2021 -

Kaikoura Earthquake Fault Ruptures 2016
Environment CanterburyMapped fault ruptures associated with the 14 November 2016 Mw7.8 Kaikoura earthquake.

Attribute descriptions are provided in Langridge, et al, 2016, The New Zealand active faults database: NZAFD250.New Zealand Journal of Geology and Geophysics 59(1).Created 9 March 2021 • Updated 14 April 2021 -
Greendale Fault Complexity 2011
Environment CanterburyFault complexity/avoidance zones for the Greendale Fault, based on the Greendale Fault traces dataset mapped after the Greendale Fault rupture in the September 2010 Darfield (Canterbury) earthquake. Areas are mapped as either well-defined, distributed or uncertain deformation, as outlined in the accompanying report.

Ashley Fault Avoidance Zone 2020
Environment CanterburyExtent of the Ashley Fault Avoidance Zones. Areas of well-defined and distributed deformation have a 20 m buffer applied as per the Ministry for the Environment guidelines. Areas of uncertain and extended deformation were considered by the report authors to not have been mapped precisely enough to warrant assigning a 20 metre buffer.

Canterbury Fault Awareness Areas 2019
Environment CanterburyThe fault awareness areas show areas where there may be a surface fault rupture hazard. Surface fault rupture is the permanent breaking, ripping, buckling or warping of the ground on or near the line where a fault meets the ground surface, as a result of movement on the fault. It is different from earthquake shaking. This dataset has been compiled from...Created 9 March 2021 • Updated 14 April 2021 -
