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 کاملSurface deformation due to a strike-slip fault in an elastic gravitational layer overlying
We extend a technique previously used to model surface displacements resulting from thrust faulting in an elastic-gravitational l yer over a viscoelastic-gravitational h f-space to the case of strike-slip faulting. The method involves the calculation of the Green's functions for a strike-slip point source contained in an elastic-gravitational layer over a viscoelastic-gravitational half-space. ...
متن کاملStructural evidence on strike slip Kinematic inversion of the Kushk-e-Nosrat Fault zone, Central Iran
NW-tending faults in Central Iran are expected to represent dominant dextral components due to their orientation with respect to the northward motion of the Arabian Plate with respect to Eurasia. However, previously published works, as well as the focal mechanism solution of the area's earthquakes, indicate evidence of sinistral kinematic along the major faults in Central Iran. Here we present ...
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 کاملfinite element modeling of deformation field induced by dip and strike slip fault coseismic activity
many earthquakes occur in iran every year and some of these earthquakes cause loss of life and property. consequently earthquake is one of challenging topics not only in iran but also in other active tectonic regions in the world. investigating the mechanism of earthquake as a natural disaster is the first and important step. to study earthquakes, different information such as geometry and beha...
