The 2012 August 11 Ahar earthquakes: consequences for tectonics and earthquake hazard in the Turkish-Iranian Plateau [PDF]

open access: yes, 2013
We have examined the faulting in the 2012 August 11 Mw 6.4 and 6.3 Ahar (NW Iran) earthquakes using a combination of field mapping, remote-sensing observations of tectonic geomorphology, the cross-correlation of optical satellite images and the inversion

The 1980, 1997 and 1998 Azores earthquakes and its seismotectonic implications [PDF]

open access: yes, 2007
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

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2016
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).

Active Faulting Geometry and Stress Pattern Near Complex Strike‐Slip Systems Along the Maghreb Region: Constraints on Active Convergence in the Western Mediterranean

open access: yesTectonics, 2018
The Maghreb region (from Tunisia to Gibraltar) is a key area in the western Mediterranean to study the active tectonics and stress pattern across the Africa‐Eurasia convergent plate boundary.

Complex microseismic activity and depth-dependent stress field changes in Wakayama, southwestern Japan

open access: yesEarth, Planets and Space, 2018
We examined the spatial relationship between seismicity and upper crustal structure in the Wakayama region, northwestern Kii Peninsula, Japan, by investigating microearthquake focal mechanisms and the local stress field.

Strike-slip deformations in the West Siberian Basin and their impact on exploration and development of oil and gas reservoirs [PDF]

open access: yes, 2009
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.

Deep ductile shear localization facilitates near-orthogonal strike-slip faulting in a thin brittle lithosphere [PDF]

open access: yes, 2020
Some active fault systems comprise near-orthogonal conjugate strike-slip faults, as highlighted by the 2019 Ridgecrest and the 2012 Indian Ocean earthquake sequences.

The El Tocuyo, Venezuela, earthquake of 3 August, 1950: Focal parameters and tectonic implications [PDF]

open access: yesGeofísica Internacional, 2001
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.

Volcano instability induced by strike-slip faulting

open access: yesBulletin of Volcanology, 2000
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.

Topographic evolution of the Eastern Alps: The influence of strike-slip faulting activity

open access: yes, 2017
We present the results of a numerical model that was used to investigate aspects of the landscape evolution of the Eastern European Alps in the Miocene.
