Controls on early‐rift geometry: new perspectives from the Bilila‐Mtakataka fault, Malawi [PDF]

Geophysical Research Letters, 2018
We use the ~110 km long Bilila‐Mtakataka fault in the amagmatic southern East African Rift, Malawi, to investigate the controls on early‐rift geometry at the scale of a major border fault.

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.

Variable Fault Geometry Suggests Detailed Fault‐Slip‐Rate Profiles and Geometries Are Needed for Fault‐Based Probabilistic Seismic Hazard Assessment (PSHA) [PDF]

Bulletin of the Seismological Society of America, 2018
It has been suggested that a better knowledge of fault locations and slip rates improves seismic hazard assessments. However, the importance of detailed along‐fault‐slip‐rate profiles and variable fault geometry has not yet been explored. We quantify the importance for modeled seismicity rates of using multiple throw‐rate measurements to construct ...

Simultaneous Bayesian Estimation of Non‐Planar Fault Geometry and Spatially‐Variable Slip

Journal of Geophysical Research: Solid Earth, 2021
Large earthquakes are usually modeled with simple planar fault surfaces or a combination of several planar fault segments. However, in general, earthquakes occur on faults that are non‐planar and exhibit significant geometrical variations in both the ...

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.

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 ...

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.
