Fault 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. At the time of the report the best estimate of recurrence interval class (long term average time between earthquakes) for the Greendale Fault was RI Class V (5,000-10,000 years). Subsequent research by Hornblow et al (2014) has placed the recurrence interval class into RI Class VI (10,000-20,000 years).Accompanying report is Villamor, P., Barrell, D., Litchfield, N., Van Dissen, R., Hornblow, S. and Levick, S., 2011, Greendale Fault investigation of surface rupture characteristics for fault avoidance zonation.GNS Science Consultancy report 2011-121, Environment Canterbury report R11/25.See also Hornblow, et al, 2014, Paleoseismology of the 2010 Mw7.1 Darfield (Canterbury) earthquake source, Greendale Fault, New Zealand.Tectonophysics 637:178-190. |
