A nearly 70 yr hiatus of major seismic activity in the central eastern Bayan Har block (BKB) ended on 22 May 2021, when a multislip-peak sinistral strike-slip earthquake struck western Maduo County, Qinghai.

Fault-surface geometry controlled by faulting mechanisms: Experimental observations in limestone faults [PDF]
Geology, 2017 Surface geometry is an essential component in faulting and earthquake dynamics, yet its evolution and interrelationship with friction are poorly understood. The geometric characteristics of smooth fault surfaces are herein investigated by combining direct shear experiment results with statistical analysis of the surface topography.

The intracontinental plate boundary, dextral North Anatolian fault (NAF), is well-known by the westward migration of the multi-segment large earthquake sequence during the twentieth century. The sequence, started by the 1939 Erzincan earthquake (Mw 7.9),

Large earthquakes on strike-slip faults often rupture multiple fault segments by jumping over stepovers. Previous studies, based on field observations or numerical modeling with a homogeneous initial stress field, have suggested that stepovers more ...

Tectonics, 2020
Precise knowledge of the geometry of faults and folds at depth is important for tectonics, economic geology, and seismic hazards. However, the geometry and kinematics of faults and the aspects controlling the coevolution of folds are difficult to ...

Hierarchical geometry of faulting
Journal of Geophysical Research: Solid Earth, 1996Several joint and fault patterns were mapped at different scales (from 1 cm to 100 km) on the sedimentary cover of Saudi Arabia. They were analyzed using a new multifractal algorithm improved to correct for irregular geometry of mapped domains and finite size effects.

Quantifying fault breccia geometry: Dent Fault, NW England
Journal of Structural Geology, 2008A geometric classification of fault breccia borrowed from the cave-collapse literature has been suggested as an alternative to available genetic classifications. Here, image analysis is used to explore geometric discrimination between the visually assigned classes of crackle breccia, mosaic breccia and chaotic breccia, using samples from the well ...

Sediment geometries and domino faulting
Geological Society, London, Special Publications, 1993Abstract A general forward modelling scheme is used to produce a model of sediment geometry in half-grabens formed during extension of domino fault blocks. The model includes the effects of erosion, sediment transport, sedimentation and isostasy and simulates both syn- and post-rift sedimentary sequences.

This meeting took place at Burlington House on 14 and 15 June 1989. Until recently a specialist structural geology meeting on a theme such as this would have been solely the preserve of the Tectonic Studies Group.

Displacement geometries along graben bounding faults
First Break, 1994The Hom Graben is a N-S striking graben structure cutting the E-W striking system of the North Sea High, It is located in the Danish and German North Sea between the Danish mainland and the Central Graben (Fig. 1). The Hom Graben as generally defined is of late Permian to Triassic age (Best et al.
