“…Figure 1). The age of fault initiation is bracketed between 2.8 Ma and 4.0 Ma (Lee et al, 2009;Burchfiel et al, 1987;Hodges et al, 1989). The latter age represents the youngest age of Pliocene basalts offset by the fault; fault initiation is reckoned to occur sometime after basalt eruption.…”

“…Alternately, it may reflect the kinematics of the Hunter Mountain Fault, which can be considered a short transfer fault linking oblique-extensional low angle normal faults to the north (Saline Valley) and south (Panamint Valley). The Panamint Valley fault is inferred to have a very shallow decollement depth (less than 1 km) based on the depth of alluvial fill in the valley (Burchfiel et al, 1987;Hodges et al, 1989). This shallow decollement may influence the mechanical behavior of the connecting Hunter Mountain fault.…”

We present new space geodetic data indicating that the present slip rate on the Hunter Mountain-Panamint Valley fault zone in Eastern California (5.0±0.5 mm/yr) is significantly faster than geologic estimates based on fault total offset and inception time. We interpret this discrepancy as evidence for an accelerating fault and propose a new model for fault initiation and evolution. In this model, fault slip rate initially increases with time; hence geologic estimates averaged over the early stages of the fault's activity will tend to underestimate the present-day rate. The model is based on geologic data (total offset and fault initiation time) and geodetic data (present day slip rate). The model assumes a monotonic increase in slip rate with time as the fault matures and straightens. The rate increase follows a simple Rayleigh cumulative distribution. Integrating the rate-time path from fault inception to present-day gives the total fault offset.

“…Nevertheless there is considerable evidence that some low-angle normal faults originated and have been active with their present-day geometry (e.g. Hodges et al, 1989). The fact that low-angle normal faults exist in an area with a minimal amount of structural exposure indicates that these geometries are not exclusive of highly extended terrains and that normal faults could originate either with a low-or high-angle geometry according to the pre-existing tectonic setting.…”

Structural analysis and field mapping together with simple geometrical and flexural elastic models, document that two styles of Quaternary extensional tectonics characterized the Gran Sasso range (central Apennines, Italy). In the western part of the range, extension took place on 10-15-km-long range-front normal faults with associated 600-1000-m-high escarpments showing evidence of Late Glacial-Holocene activity. This topography has been reproduced with a thin elastic plate subjected to the isostatic forces induced by the movement along high-angle (55º-65º) planar normal faults. In the eastern part of the belt extension occurred on shallow-dipping normal faults (30º-35º) which reactivated progressively deeper pre-existing thrusts. In this area antithetic 'domino' faults formed to accommodate the mechanical adjustment of the hanging-wall over a variably dipping major fault surface. The eastward increase in shortening, due to the earlier compressional phase, documented in the Gran Sasso belt by previous authors, accounts for the more developed zones of weakness and high topographic relief in the eastern sector. This setting could explain the different styles of extension and the more advanced northeastern limit of normal faulting in the eastern sector. This work suggests that normal faults can originate either with low-or high-angle geometry in the upper crust according to the pre-existing tectonic setting and that topography could be important in controlling the geometry and pattern of migrating normal faulting.

Mitigation of atmospheric phase delays in InSAR data, with application to the eastern California shear zone

We present a method for estimating radar phase delays due to propagation through the troposphere and the ionosphere based on the averaging of redundant interferograms that share a common scene. Estimated atmospheric contributions can then be subtracted from the radar interferograms to improve measurements of surface deformation. Inversions using synthetic data demonstrate that this procedure can considerably reduce scatter in the time series of the line‐of‐sight displacements. We demonstrate the feasibility of this method by comparing the interferometric synthetic aperture radar (InSAR) time series derived from ERS‐1/2 and Envisat data to continuous Global Positioning System data from eastern California. We also present results from several sites in the eastern California shear zone where anomalous deformation has been reported by previous studies, including the Blackwater fault, the Hunter Mountain fault, and the Coso geothermal plant.
