Description: There are four maindata fields. 'AREA' gives the extent of each polygon in square metres. 'Feature' identifies the Fault Avoidance Zonation unit type, based largely on the 'TYPE' field in the Ground Deformation Map dataset.. 'FAZ_class' identifies the category of fault complexity, as set out in Table 2 of the report.'NAME' identifiesthe fault or other landform unit with which the FAZ unit polygon is associated.This dataset was compiled for presentation at a scale of 1:35,000 in the report, but the data were captured at more detailed scales.The dataset is derived from the ground deformation classes dataset. Accuracy of the polygon boundaries is the same as for the Geomorphologic map unit dataset. The geomorphologic map units were drawn on-screen at a scale of approximately 1:10,000, except for tectonic landform map units, which were mapped at ~1:5,000 scale. Locations of the boundaries of the map unit boundaries are considered to be accurate to about +/- 30 m, apart from the tectonic landform unit boundaries, which are considered to be accurate to +/- 10 m at best on the younger river terraces (Okuku Terrace 3/Makerikeri Terrace 2 and younger), but are no better than +/- 20 m on older terrace or hill landforms.

Description: The data structure and accuracy is identical to the Fault Avoidance Zone dataset, with the addition of the field 'BUFF_DIST' which states the width of the added buffer (20 m in all cases).

Description: This active fault dataset, prepared by GNS Science under contract to Canterbury Regional Council (ECan), is based on the GNS Science QMAP (Quarter-Million-scale) geological map dataset 'faults' layer. The base dataset was extracted from the QMAP 'seamless' dataset in mid-2014, and modified by the addition of three new attribute fields, and in some cases the repositioning of some faults or parts of faults, or the addition of new faults. The three new attribute fields are:KDC_name (local names for the mapped features)Certainty (see report text)Surf_form (see report text)In order to make clear the linkage between the QMAP dataset and the amended dataset prepared as part of this project, all the attributes of the QMAP dataset are retained, without modification, in these shapefiles. For this report, all amendments are contained within three additional data fields. Any newly identified faults mapped as part of the ECan project are identifiable by the lack of any QMAP attributes. All the data have been compiled at a regional scale (1:250,000) and the locations of active faults are +/- 100 m at best, but more commonly +/- 250 m.

Description: Tsunami Evacuation Zones in the Canterbury Region. These zones are made up of a collection of data from District Councils around Canterbury. The red zone is the shore exclusion area and the orange zone is the land evacuation area.
