Segmentation of the Main Himalayan Thrust Illuminated by Bayesian Inference of Interseismic Coupling [PDF]

Geophysical Research Letters, 2020
We use a recent compilation of geodetic data of surface displacements in a fully Bayesian approach to derive a probabilistic estimate of interseismic coupling along the Main Himalayan Thrust (MHT).

Geodetic Constraints on Segment-Scale Slip Rates and Interseismic Coupling Along the Havran–Balıkesir Fault Zone, NW Anatolia, Türkiye [PDF]

Sensors
This study presents a new high-resolution GNSS-derived velocity field and the first internally consistent, segment-resolved block model for the Havran–Balıkesir Fault Zone (HBFZ) in western Anatolia.

Fault valving and pore pressure evolution in simulations of earthquake sequences and aseismic slip [PDF]

Nature Communications, 2020
Coupling between fault zone fluid flow, permeability evolution, and elastic stress transfer produces fault valving and fluid-driven aseismic slip and pore pressure pulses.

Interseismic Coupling, Asperity Distribution, and Earthquake Potential on Major Faults in Southeastern Tibet

Geophysical Research Letters, 2023
Southeastern (SE) Tibet is one of the most seismically active regions in mainland China, but the spatial distribution of interseismic coupling that quantifies seismic hazard is unknown along most major faults.

3D architecture and complex behavior along the simple central San Andreas fault [PDF]

Nature Communications
The central San Andreas Fault (CSAF) exhibits a simple linear large-scale fault geometry, yet seismic and aseismic deformation features vary in a complex way along the fault. Here we investigate fault zone behaviors using geodetic observation, seismicity

Potential Bias in Inferred Megathrust Slip Rates Induced by the Neglect of Material Heterogeneity

Geophysical Research Letters
Accurate knowledge of the pattern of interseismic coupling on megathrusts is critical to preparing for future earthquakes and tsunamis. However, published models for a given fault zone commonly differ widely, making hazard assessment difficult ...

Interseismic Coupling beneath the Sikkim–Bhutan Himalaya Constrained by GPS Measurements and Its Implication for Strain Segmentation and Seismic Activity

Remote Sensing, 2020
The Sikkim–Bhutan seismic gap has witnessed a long earthquake quiescence since the 1714 M7.5~8.5 earthquake. The state of stress accumulation beneath the Sikkim–Bhutan Himalaya and its spatial correlation with seismicity remains unclear due to the lack ...

Bridging the gap between subduction dynamics and the long-term strength of the Sunda megathrust [PDF]

Nature Communications
The link between great earthquakes and subduction dynamics across a wide range of scales remains a crucial, yet elusive, tenet of the seismotectonics of convergent margins. Here, we show high-performance computational simulations of the three-dimensional

Coupling fraction model to interpret the motion of non-fully coupled strike-slip faults

Frontiers in Earth Science, 2023
Despite coupling fractions being extensively used in the interseismic period, the coexistence of locking and creeping mechanisms and the correlation between the coupling fraction and locking depth remain poorly understood because of the lack of a ...

Physics-Based Approach to Deep Interseismic Creep: Implications for North Tabriz Fault Behavior Using MCMC

Engineering Proceedings, 2023
Many studies assume that the distribution of a fault slip rate remains constant with time when examining surface deformation. However, recent numerical simulations have shown that dynamic rupture can penetrate regions with increased friction and diffuse ...
