Three-dimensional approach to understanding the relationship between the Plio–Quaternary stress field and tectonic inversion in the Triassic Cuyo Basin, Argentina [PDF]
The Cacheuta sub-basin of the Triassic Cuyo Basin is an example of rift basin inversion contemporaneous to the advance of the Andean thrust front, during the Plio–Quaternary. This basin is one of the most important sedimentary basins in

关于2021年5月滇西漾濞MS6.4地震序列特征及成因的初步研究
2021年5月21日21时48分在滇西苍山西麓漾濞地区发生MS6.4 (MW6.1)强震,相关地震活动表现为一个典型的前震−主震−余震序列。本研究分别就该地震序列的构造背景、M1.0以上地震的双差定位、主要地震的矩张量反演和破裂传播方向、应力场反演及断层滑动趋势以及潮汐作用等方面进行了初步分析。矩张量反演结果表明,矩心深度为6.0 km。根据断层破裂传播方向分析结果及精定位余震分布判定,主震震源断层产状为走向137°,倾角75°,滑动角−167°,破裂沿南东向单侧扩展,右旋走滑含正断层分量 ...

Modification of the lithospheric stress field by lateral variations in plate-mantle coupling [PDF]
The presence of deeply penetrating continental roots may locally increase the magnitude of basal shear tractions by up to a factor of 4 compared to a layered viscosity structure.

Waveform inversion of the S reflector west of Spain: fine structure of a detachment fault. [PDF]
The S reflection west of Iberia has been interpreted as a low-angle detachment fault separating crustal fault blocks from partially serpentinized mantle. We apply full waveform inversion to investigate the fine structure of S.

Contemporary stress and strain field in the Mediterranean from stress inversion of focal mechanisms and GPS data [PDF]
Abstract Mapping the contemporary stress field of the Mediterranean provides fundamental insights on the complexity of plate tectonic forces throughout the region and at different depths. Despite increased data availability and methodological improvements, most recent comprehensive stress field characterization across the entire Mediterranean dates ...

Study on tectonic stress field in Yingjiang area based on multi-focal mechanism solution sequence
In this paper,a total of 162 focal mechanism solutions are collected from several focal mechanism solution sequences in Yingjiang area,and the tectonic stress field inversion is carried out from Sudian fault to Dayingjiang fault.

Stress field characterisation in Nickel Rim South Mine using seismic stress inversion [PDF]
Knowledge of stresses is important for many aspects of mine design, but conventional methods of measuring stresses produce estimates at only a limited number of points in space and time. Furthermore, stresses are known to be affected by geological structures, particularly faults, but mapping of how the stress field is affected by such structures is not
