The role of mechanical stratigraphy on the refraction of strike-slip faults [PDF]

Solid Earth, 2019
Fault and fracture planes (FFPs) affecting multilayer sequences can be significantly refracted at layer–layer interfaces due to the different mechanical properties of the contiguous layers, such as shear strength, friction coefficient and grain size ...

Stress rotations and the long-term weakness of the Median Tectonic Line and the Rokko-Awaji Segment [PDF]

, 2014
International audienceWe used a field analysis of rock deformation microstructures and mesostructures to reconstructthe long-term orientation of stresses around two major active fault systems in Japan, the Median TectonicLine and the Rokko-Awaji Segment.

Constraining the Kinematics of the Victoria Microplate and the Northern Western Branch of the East African Rift System

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The fragmentation of continents results in microplates that rotate to accommodate the lateral propagation of bounding rifts. Yet, the relationships between microplate rotation rates, fault slip, and kinematics at propagating rift tips remain unknown.

Analysis of an anthropogenically-induced landslide with emphasis on geological precursors

Results in Earth Sciences
A landslide occurred at Nhachüko on 2nd June 2017. Indiscriminate dumping of hill-cut debris along a narrow stream channel blocked the flow of water, which raised the water levels on the uphill side.

THE TECTONOPHYSICAL RESEARCHES OF THE SEMISAMSKAYA ANTICLINE (NORTH-WESTERN CAUCASUS FOLD AND THRUST BELT)

Геодинамика и тектонофизика, 2015
Structural paragenetic and cataclastic analysis methods were applied to study tectonic fracturing within one of the folds of the southern wing of the North-Western Caucasus fold-and-thrust belt. The object of the study was the Semisamskaya anticline (Fig.

Morphometric Evidence for Cenozoic Intraplate Reactivation in NW Uruguay

Tectonics, Volume 44, Issue 10, October 2025.
Abstract Located in eastern South America, Uruguay has been considered tectonically inactive since rifting in the Late Cretaceous. Here, we use a high‐resolution digital elevation model and field observations to investigate the presence of recent tectonic activity in the Basaltic Plateau, northwest Uruguay.

Determination of present-day stress tensor and neotectonic interval in the Spanish Central System and Madrid Basin, central Spain [PDF]

, 1996
A brittle deformation tectonic analysis was performed in central Spain (Spanish Central System and Madrid Basin) in order to decipher and understand the deformation processes that take place in a typical intracontinental zone.

Interaction Between Transverse and Rift Faults During the Initiation of Orogenic Extension: The Case of Sant'Anna Pelago (Northern Apennines, Italy)

Tectonics, Volume 44, Issue 9, September 2025.
Abstract Sant'Anna Pelago is located near the extensional front of the Northern Apennines (Italy) between Modena and Lucca, an area characterized by multiple lateral steps of the NW‐SE striking tectonic system and orographic divide. The region is affected by significant instrumental seismicity with over a thousand recorded events (0.5 < M < 4.8) from ...

All Aligned on the Western Front of North America? Analyzing the Stress Field in the Northern Cordillera

Tectonics, Volume 44, Issue 9, September 2025.
Abstract This study presents the first rigorous statistical analysis of the present‐day crustal stress along the western margin of the North American Plate, covering the entire Canadian Cordillera and Alaska. Using circular statistics and geometric tests, we develop a regional stress province model that constrains the directions of first‐order stresses.
