Fault step-overs with linking dip-slip faults are common features on long strike-slip fault systems worldwide. It has been noted by various researchers that under some circumstances, earthquakes can jump across fault step-overs to cascade into large events, while under other circumstances rupture is arrested at stepovers. There is also evidence that fault step-overs may be preferential location...

[1] On Venus a 1000-km-long, 50to 200-km-wide, anastomosing shear zone system (Thetis Boundary Shear Zone (TBSZ)) separates the eastern Ovda and northwestern Thetis Regiones. Previous workers mapped a part of this shear zone and interpreted it as a sinistral strike-slip shear zone containing an extensional jog. In the present study it is reexamined for a detailed structural and kinematic analys...

The opposite-sense fault block rotation across the continental strike-slip faulting plays an important role in accommodating crustal deformation north of East Iran orogen. This research constrains post-Neogene kinematics NW-SE to E-W left-lateral transpressional zones at northern termination N-S striking right-lateral Neh system Using two case studies, we analyzed Birjand splay and Shekarab tra...

On 16 September 2015, a great (Mw 8.3) interplate thrust earthquake ruptured offshore Illapel, Chile, producing a 4.7-m local tsunami. The last major rupture in the region was a 1943 MS 7.9 event. Seismic methods for rapidly characterizing the source process, of value for tsunami warning, were applied. The source moment tensor could be obtained robustly by W-phase inversion both within minutes ...
