Determination of the northeast section of the Nanyuan–Tongxian fault in Beijing and research on its Quaternary activity

open access: yesDizhi lixue xuebao, 2023
The Nanyuan–Tongxian fault is the boundary fault between the Beijing depression and the Daxing uplift, also the primary seismic-controlling fault of the Beijing M \begin{document}$ 6{\dfrac{1}{2}}$\end{document} earthquake in 1665.

Sea Beam Survey of an Active Strike-Slip Fault: The San Clemente Fault in the California Continental Borderland [PDF]

open access: yes, 1989
The San Clemente fault, located in the California Continental Borderland, is an active, northwest trending, right-lateral, wrench fault. Sea Beam data are used to map the major tectonic landforms associated with active submarine faulting in detail ...

Secondary Fault Activity of the North Anatolian Fault near Avcilar, Southwest of Istanbul: Evidence from SAR Interferometry Observations

open access: yesRemote Sensing, 2016
Strike-slip faults may be traced along thousands of kilometers, e.g., the San Andreas Fault (USA) or the North Anatolian Fault (Turkey). A closer look at such continental-scale strike faults reveals localized complexities in fault geometry, associated ...

Quaternary rupture of a crustal fault beneath Victoria, British Columbia, Canada [PDF]

open access: yes, 2017
The seismic potential of crustal faults within the forearc of the northern Cascadia subduction zone in British Columbia has remained elusive, despite the recognition of recent seismic activity on nearby fault systems within the Juan de Fuca Strait.

Fluid-induced high seismicity in Songliao Basin of China

open access: yesEuropean Journal of Remote Sensing, 2020
In recent years, moderate earthquakes with a magnitude of about 5.0 have occurred along the Fuyu/Songyuan-Zhaodong fault frequently. This fault is the most seismic active fault in the Songliao Basin, even in the Northeast Seismic Region of China.

Discussion on the “Luanxian-Leting fault”

open access: yes地震科学进展, 2020
“Luanxian-Leting fault”is an inferred fault. Recent petroleum geophysical data reveals that the “Luanxian-Leting fault”does not exist in the east of Changli fault.

Responses of Stream Geomorphic Indices to Piedmont Fault Activity in the Northern Segment of the Red River Fault Zone

open access: yesRemote Sensing, 2023
Based on a digital elevation model (DEM) and GIS technology, we extracted and analyzed stream geomorphic indices—such as the slope, relief degree of the land surface (RDLS), hypsometric integral (HI) and channel steepness index (ksn)—of the Cangshan ...

The active Main Marmara Fault

open access: yesEarth and Planetary Science Letters, 2001
Abstract This paper presents selections from and a synthesis of a high resolution bathymetric, sparker and deep-towed seismic reflection data set recently acquired by the French Ifremer R.V. Le Suroit in an E–W deep trough that forms the northern half of the Sea of Marmara in NW Turkey.

吉兰泰断陷盆地周缘断裂带气体释放及其对断层活动性的指示意义

open access: yesDizhen xuebao, 2019
为了研究吉兰泰断陷盆地周缘断裂带气体排放及其对断层活动性的指示意义,在盆地周缘4条活动断裂上布设了5条土壤气测量剖面和1条电磁测量剖面,观测了土壤气中Rn,Hg和CO2的浓度、释放通量和地电阻率,对各测量剖面进行了土壤化学组分分析,计算得到了断层活动性相对指数KQ。研究结果显示:土壤气体CO2和Rn受渗透性较低的粉砂土阻挡,主要沿结构破碎的断层上盘逃逸,并形成浓度高峰;吉兰泰盆地南缘土壤气Rn,Hg和CO2的浓度和释放通量最高,可能与盆地西南缘花岗岩中U和Ra的运移以及盆地南缘碳酸盐岩的分解有一定的关系。

Geomorphic signal of active faulting at the northern edge of Lut Block. Insights on the kinematic scenario of Central Iran [PDF]

open access: yes, 2016
Recent works documented Neogene to Quaternary dextral strike-slip tectonics along the Kuh-e-Sarhangi and Kuh-e-Faghan intraplate strike-slip faults at the northern edge of the Lut Block of Central Iran, previously thought to be dominated by sinistral ...
