Reconstructing the Geometry of the Yushu Fault in the Tibetan Plateau Using TLS, GPR and Trenching

Remote Sensing, 2023
Although geomorphic evidence and shallow geometry of active faults are significant for the understanding and assessing of fault activity and seismic hazards, it is challenging to acquire high-resolution topographic data and shallow geometry of the Yushu ...

Fault geometry and earthquake mechanics

Annals of Geophysics, 1994
Earthquake mechanics may be determined by the geometry of a fault system. Slip on a fractal branching fault surface can explain: 1) regeneration of stress irregularities in an earthquake; 2) the concentration of stress drop in an earthquake into ...

Test on the Reliability of the Subsurface Fault Geometry Estimated by Deformed River Terraces Along the Bailang River, North Front of the Qilian Shan (North West China)

Frontiers in Earth Science, 2021
The subsurface fault geometry is the base for understanding a process of crust deformation and mountain building. Based on kinematic models for fault-related folds, a geomorphic method is recently applied to estimate the subsurface fault geometry, while ...

Using terrestrial LiDAR to accurately measure the microgeomorphologic geometry of active fault: A case study of fault scarp on the Maoyaba fault zone

Dizhi lixue xuebao, 2021
The micro-geomorphologic geometry of active fault is often complex due to the natural dynamics, such as high degree of sedimentation and erosion, and man-made activities.

Seismicity-based 3D model of ruptured seismogenic faults in the North-South Seismic Belt, China

Frontiers in Earth Science, 2023
The North–South Seismic Belt produces the most frequent strong earthquakes in the Chinese continental region, such as the MS 8.0 Wenchuan earthquake on 12 May 2008 and Ms 7.0 Lushan earthquake on 20 April 2013.

Fault geometry and kinematics of the 2021 Mw 7.3 Maduo earthquake from aftershocks and InSAR observations

Frontiers in Earth Science, 2022
The 2021 Mw 7.3 Maduo earthquake revealed the significant seismic hazard of faults developed within the Bayan Har Block of eastern Tibet, China (e.g., the Kunlun Pass–Jiangcuo Fault).

Dynamic rupture simulation of 2018, Hokkaido Eastern Iburi earthquake: role of non-planar geometry

Earth, Planets and Space, 2020
The 2018, Hokkaido Eastern Iburi, Japan, earthquake is an event characterized by complexity of the rupture process and slip pattern, which may involve both reverse and strike-slip motion depending on the locations on the fault surface. We perform dynamic

Construction of fault geometry by finite-fault inversion of teleseismic data [PDF]

Geophysical Journal International, 2020
SUMMARYConventional seismic source inversion estimates the earthquake rupture process on an assumed fault plane that is determined a priori. It has been a difficult challenge to obtain the fault geometry together with the rupture process by seismic source inversion because of the nonlinearity of the inversion technique.
