Slip rate and locking degree of Haiyuan fault zone, northeastern Qinghai-Xizang plateau, based on refined block model and GPS data

Geodesy and Geodynamics
As a major fault in the northeastern Qinghai-Xizang Plateau, the Haiyuan fault zone is important for understanding the regional deformation. Aiming at the differences in the slip rate and locking degree obtained from different studies, this study ...

Present‐Day Activity of the Anninghe Fault and Zemuhe Fault, Southeastern Tibetan Plateau, Derived From Soil Gas CO2 Emissions and Locking Degree

Earth and Space Science, 2021
The Anninghe fault (ANHF) and the Zemuhe fault (ZMHF), located in the southeast of the Tibetan Plateau, have a high level of seismic hazard and are among the most active faults in China.

Fault locking of the Qilian–Haiyuan fault zone before the 2022 Menyuan Ms6.9 earthquake and its seismic hazards in the future

Frontiers in Earth Science, 2022
By using GPS-derived velocities of 2015–2021 and a negative dislocation program, we inverted the locking degree and slip rate deficit in the Qilian–Haiyuan fault zone, and combined with the distribution of small earthquakes in the fault, we studied the ...

Interseismic Locking of the Xiaojiang Fault May Be Controlled by Pore Fluid Pressure

Geophysical Research Letters
Although fault locking state has been widely acquired with space geodetic observations, the mechanisms controlling fault locking are poorly known.

Present‐Day Activity of the Anninghe Fault and Zemuhe Fault, Southeastern Tibetan Plateau, Derived From Soil Gas CO₂Emissions and Locking Degree [PDF]

Earth and Space Science, 2021
AbstractThe Anninghe fault (ANHF) and the Zemuhe fault (ZMHF), located in the southeast of the Tibetan Plateau, have a high level of seismic hazard and are among the most active faults in China. This study performed the first measurements of soil gas CO2at three sites across the ANHF and the ZMHF.

Interseismic Slip and Coupling along the Haiyuan Fault Zone Constrained by InSAR and GPS Measurements

Remote Sensing, 2021
The Haiyuan fault zone is an important tectonic boundary and strong seismic activity belt in northeastern Tibet, but no major earthquake has occurred in the past ∼100 years, since the Haiyuan M8.5 event in 1920.

The 8 January 2022, Menyuan Earthquake in Qinghai, China: A Representative Event in the Qilian-Haiyuan Fault Zone Observed Using Sentinel-1 SAR Images

Remote Sensing, 2022
On 8 January 2022, a Ms 6.9 earthquake occurred in Menyuan, Qinghai, China. This event provided important geodetic data before and after the earthquake, facilitating the investigation of the slip balance along the seismogenic faults to understand ...

Dynamic deformation and fault locking of the Xianshuihe Fault Zone, Southeastern Tibetan Plateau: implications for seismic hazards

Earth, Planets and Space, 2022
The Xianshuihe Fault Zone is one of the most historically seismically active regions in mainland China. However, the seismicity along this fault zone has been quiescent for the past 40 years, since the Daofu M6.9 earthquake in 1981.

Kinematics Analysis and Singularity Avoidance of a Parallel Mechanism with Kinematic Redundancy

Chinese Journal of Mechanical Engineering, 2022
The kinematic redundancy is considered as a way to improve the performance of the parallel mechanism. In this paper, the kinematics performance of a three degree-of-freedom parallel mechanism with kinematic redundancy (3-DOF PM-KR) and the influence of ...

Present-day strain accumulation in the Liupan Shan area, northeastern margin of the Tibetan Plateau by GPS observations

Terrestrial, Atmospheric and Oceanic Sciences, 2019
We derived a new GPS site velocity field by integrating the data of ten newly built stations across the Liupan Shan Fault, in the northeastern margin of the Tibetan Plateau and those of pre-existing sites in this area for the period of 1999 - 2015.
