Scaling of Fault Parameters for Continental Strike-Slip Earthquakes
The long-standing conflict between the predictions of elastic dislocation models and the observation that average coseismic slip increases with rupture length is resolved with application of a simple displacement-depth function and the assumption that the base of the seismogenic zone does not result from the onset of viscous relaxation but rather a transition to stable sliding in a medium that ...
متن کاملStrike-slip fault patterns on Europa: Obliquity or polar wander?
Variations in diurnal tidal stress due to Europa’s eccentric orbit have been considered as the driver of strike-slip motion along pre-existing faults, but obliquity and physical libration have not been taken into account. The first objective of this work is to examine the effects of obliquity on the predicted global pattern of fault slip directions based on a tidal-tectonic formation model. Our...
متن کاملThe distributions of slip rate and ductile deformation in a strike- slip shear zone
A simple mechanical model and dimensional analysis are used to derive a scaling law for the partitioning between slip rate on a strike-slip fault and distributed deformation in the far-field. The depth of the fault, the distributions of stress, strain rate and slip rate are solved for a given far-field force or displacement in a 2-D medium with a linear temperature-dependent viscous rheology. A...
متن کاملA ductile shear zone terminating a brittle strike-slip fault: The gypsum- dominated Paluzza-Comeglians shear zone as western extension of the Fella- Save fault, Southern Alps
Compressive and extensive horsetails are common structures on the lateral termination of brittle strike-slip faults, which forms within the shallow continental crust. Here we report another possibility, the lateral termination of a brittle strike-slip fault in a formation-parallel low-temperature ductile shear zone within sulphatic, gypsum-dominated evaporites. In the Southern Alps, over a dist...
متن کاملShear strain concentration mechanism in the lower crust below an intraplate strike-slip fault based on rheological laws of rocks
We conduct a two-dimensional numerical experiment on the lower crust under an intraplate strike-slip fault based on laboratory-derived power-law rheologies considering the effects of grain size and water. To understand the effects of far-field loading and material properties on the deformation of the lower crust on a geological time scale, we assume steady fault sliding on the fault in the uppe...
