This
file contains fault mapping used to construct Fault Avoidance Zones and
Fault Awareness Areas for active and possibly active faults in the
TararuaDistrict (GNS CR2021/03). The faults were mapped using LiDAR
data, a regional Digital Surface Model provided by Horizons Regional
Council, data extracted from previous published mapping and from the
current Geological Map of New Zealand 1:250,000 (Heron 2018) and updated
where possible. Faults were mapped at scales between 1:5000 and
1:250,000where possible.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 created for active faults outside of the Priority Areas and
modified from the methodology recommended in Barrell et al. (2015)
"Guidelines for using regional-scale earthquake fault information in
Canterbury". GNS Science Consultancy Report 2014/211.These data should be used in conjunction with the associated GNS Science report (GNS CR2021/03).This
report has been prepared by the Institute of Geological and Nuclear
Sciences Limited (GNS Science) exclusively for and under contract to
