“…In these settings, active faults can remain unidentified, despite their potential for producing damaging earthquakes. For example, the 2010 M w 7.1 Darfield earthquake in New Zealand occurred on a previously unknown fault and produced deformation over a 30–300 m wide zone in a post–Last Glacial Alluvial Outwash surface [ Barrell et al ., ; Elliott et al ., ; Quigley et al ., ]. Similarly, surface slip along the previously unmapped Indiviso fault during the 2010 M w 7.2 El Mayor‐Cucapah earthquake was distributed in unconsolidated, water‐saturated deltaic sediments and resulted in a diffuse, kilometer‐scale warping of the surface [e.g., Oskin et al ., ].…”

[1] The Grizzly Valley fault system (GVFS) strikes northwestward across Sierra Valley, a low-relief basin situated within a network of active dextral slip faults in the northern Walker Lane, California. Quaternary motion along the Grizzly Valley fault system has not been previously documented. We used high-resolution (0.25 m) airborne lidar data in combination with high-resolution, P wave, seismic reflection imaging to evaluate Quaternary deformation associated with the GVFS. We identified suspected tectonic lineaments using the lidar data and collected seismic reflection data along six profiles across the lineaments. The seismic reflection images reveal a deformed basal marker that we interpret to be the top of Tertiary volcanic rocks overlain by a 120-450 m thick suite of subhorizontal reflectors that we interpret to be Plio-Pleistocene lacustrine deposits. Three profiles image features that we interpret to be the principal active trace of the GVFS, which is a steeply dipping fault zone that vertically offsets the volcanic rocks and the lacustrine basin fill. These data suggest that the GVFS may have been active in latest Quaternary time because (1) the lidar data show subtle surficial geomorphic features that are typical of youthful faulting, including a topographic lineament marked by an~1 m high ridge composed of discontinuous, left-stepping lobes, and (2) the seismic profiles demonstrate shallow faulting of the lacustrine strata that coincides with the left-stepping ridge. This investigation illustrates the potential for unidentified, low-rate, strike-slip faults in basins and emphasizes the value of high-resolution topographic data and subsurface imaging as a means of identifying these structures.

“…1B and 2) (Beavan et al, 2012). All remained blind, apart from the Greendale fault, which produced an ~30-km-long surface rupture, predominantly strike slip with dextral sense (Quigley et al, 2010a(Quigley et al, , 2010bBarrell et al, 2011). The Greendale fault lies in a large sedimentary basin .…”

“…Dextral displacement of up to ~5.3 m on the Central segment decreases to ~1.2 m on the West segment . The West segment displayed a notably south-side-up vertical component of offset (~1.5 m), which caused temporary partial avulsion of the Hororata River (Quigley et al, 2010b;Barrell et al, 2011) (Fig. 2).…”

“…2). Barrell et al (2011) and Quigley et al (2012) reported that much of the dextral displacement, especially on the East segment, was accommodated by horizontal fl exure that was mappable only with reference to previously linear features. The West segment scarp was rounded rather than sharp, and involved displacement of the order of 1 m, distributed over a zone typically ~20 m wide (Fig.…”

Rupture of the Greendale Fault during the 4 September 2010, M W 7.1 Darfield (Canterbury) earthquake produced a zone of ground-surface rupture that severely damaged several houses, buildings and lifelines. Immediately after the earthquake, surface rupture features were mapped in the field and from digital terrain models developed from airborne Light Detection and Ranging (lidar) data. To enable rebuild decisions to be made and for future land use planning, a fault avoidance zone was defined for the Greendale Fault following the Ministry for the Environment guidelines on 'Planning for the Development of Land on or Close to Active Faults'. We present here the most detailed map to date of the fault trace and describe how this was used to define and characterise the fault avoidance zone for land use planning purposes.
