Description: <DIV STYLE="text-align:Left;"><DIV><DIV>Overlay indicating specific Earthquake Fault Infrastructures or Facilities Awareness, and was supplied for the purpose of the 2020 District PlanMetadata Description from the E-can: - Suggested_Timaru_fault_hazard_important_infrastructure_or_facilities_overlay Shapefile: - Suggested fault hazard (important infrastructure or facilities)overlay for the Timaru District Plan, May 2020.The suggested Timaru fault hazard (important infrastructure or facilities) overlay comprises all fault awareness areas in Timaru from the Canterbury fault awareness areas2019 dataset, as recommended in Barrell, et al, 2015, Guidelines for using regional-scale earthquake fault information in Canterbury. GNS Science Consultancy Report 2014/211. See this report, and the metadata for the Canterbury fault awareness areas 2019 dataset,for more detail on how the fault awareness areas were created.The 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.The suggested Timaru fault hazard (important infrastructure or facilities) overlay is where the fault rupture hazard should be specifically considered and the fault rupture deformation areas mapped as part of a consent for important or critical infrastructure or facilities (as defined in the Timaru District Plan).Descriptions of the attribute fields:Name: - Fault name, taken from the district fault name field (e.g. TDC_name) in the district fault datasets. Some of these have been changed from the original district fault names to make them consistent with what is given in the district fault report.Zone: - Fault zone that the fault is within, if any.Certainty: - The level of confidence that the mapped feature is in fact an active earthquake fault - definite, likely or possible. See Barrell, et al, 2015 for full descriptions.Surface form: - How clearly the mapped feature can be seen at the ground surface - well expressed, moderately expressed, not expressed or unknown. See "Barrell, et al, 201"- for full descriptions.Min RI: - Minimum fault recurrence interval, taken from the summary table of each district fault report.Max RI: - Maximum fault recurrence interval, taken from the summary table of each district fault report.Min RI Class: - Minimum fault recurrence interval class (as defined in Kerr, et al, 2003, Guidelines for development of land on or close to active faults), taken from the summary table of each district fault report. Some values have been changed to better match the minimum fault recurrence interval.Max RI Class: - Maximum fault recurrence interval class (as defined in Kerr, et al 2003, Guidelines for development of land on or close to active faults), taken from the summary table of each district fault report. Type: - Whether the mapped feature is a fault (fault reaches the ground surface) or a monocline (fault stops below the ground surface but forms a fold in the ground surface).Buffer m: - Whether a 125m or 250m buffer has been applied to the fault to create the fault awareness area as per Barrell, et al, 2015.Other technical field: - such accuracy, sense of movement, dip direction, down quadrant, trend and facing, as well as territorial authority (all Timaru) have been removed for simplicity but this information can be found in the Canterbury fault awareness areas 2019 dataset.----------------------------------------------------------------------------Grouping: - District Wide MatterSub Group: - Natural Hazard------------------------------------------------------------------------------Layer Shape file provided by: - Helen Jack, Senior Scientist, at Environment Canterbury - ECANDate that the Layer was provided: - 22nd of May 2020------------------------------------------------------------------------------</DIV></DIV></DIV>
