Stochastic strike-slip fault as earthquake source model
It is known that the source of a tectonic earthquake in the framework of the theory of elasticity and viscoelasticity is considered as a displacement along a certain fault surface. Usually, when describing the source, the geometry of the fault surface is simplified to a flat rectangular area. The displacement vector is assumed to be constant.

The 1980, 1997 and 1998 Azores earthquakes and its seismotectonic implications [PDF]
We have studied the focal mechanisms of the 1980, 1997 and 1998 earthquakes in the Azores region from body-wave inversion of digital GDSN (Global Digital Seismograph Network) and broadband data. For the 1980 and 1998 shocks, we have obtained strike– slip

Tectonic Implication of the 5th March 2005, Doublet Earthquake in Ilan, Taiwan
The 5th March 2005 earthquake doublet focal mechanism was determined as strike-slip faulting from Harvard and BATS moment tensor inversion. However, based on first motion polarities, the first shock has a normal focal mechanism (Wu et al. 2008a).

Strike-slip deformations in the West Siberian Basin and their impact on exploration and development of oil and gas reservoirs [PDF]
Extensive 3D seismic exploration has revealed in much of the West Siberian petroliferous basin area a special type of faults and deformations within the sedimentary cover, caused by low-separation basement strike-slip faults.

The El Tocuyo, Venezuela, earthquake of 3 August, 1950: Focal parameters and tectonic implications [PDF]
The El Tocuyo earthquake of 1950 event was associated with the Boconó fault system. The Ms magnitude was 6.3; the focal depth was ( from pP – P and sP – P) 18 ± 1 Km.

Spatio-temporal evolution of intraplate strike-slip faulting: the Neogene-Quaternary Kuh-e-Faghan Fault, Central Iran [PDF]
Central Iran provides an ideal region to study the long-term morphotectonic response to the nucleation and propagation of intraplate faulting. In this study, a multidisciplinary approach that integrates structural and stratigraphic field investigations ...

Deep ductile shear localization facilitates near-orthogonal strike-slip faulting in a thin brittle lithosphere [PDF]
Some active fault systems comprise near-orthogonal conjugate strike-slip faults, as highlighted by the 2019 Ridgecrest and the 2012 Indian Ocean earthquake sequences.

Volcano instability induced by strike-slip faulting
Analogue sand cone experiments were conducted to study instability generated on volcanic cones by basal strike-slip movement. The results of the analogue models demonstrate that edifice instability may be generated when strike-slip faults underlying a volcano move as a result of tectonic adjustment.

Seismicity and Active Compressional Tectonics in Santa Monica Bay, Southern California [PDF]
During 1973–1986 the seismicity in Santa Monica Bay consisted of an average of four events per year of M_L ≥ 2.5, in addition to the 1979 Malibu (M_L = 5.0) mainshock-aftershock sequence.
