3-D numerical modelling of the feedback between deformation and thermal structure during subduction initiation for the French Lesser Antilles
E. Momoh, S. Tait, H. S. Bhat
We used 3-D thermomechanical modelling to investigate conditions during subduction-zone initiation and early thermal development with focus on the Lesser Antilles. Our model impose…
Coupled Transient Processes Govern Intraplate Earthquake Swarm Evolution: Insights from the 2019-2020 Palghar Sequence
Ratna Bhagat, Pathikrit Bhattacharya, K. M. Sreejith +2
Earthquake swarms provide a natural window into fault response to transient perturbations, yet their driving processes are commonly interpreted using fluid-driven and aseismic-slip…
Tidal sensitivity of tremors in a mixed fast and slow earthquake system in northeastern Japan
Yishuo Zhou, Hideo Aochi, Alexandre Schubnel +2
Tidal modulation of tectonic tremors provides a sensitive measure of fault response to small stress perturbations, yet how this response varies in a mixed fast and slow earthquake…
Supershear Rupture Indicator in Near-fault Particle Motion
Suli Yao, Hongfeng yang, Harsha S. Bhat +1
Earthquake rupture propagation speed is an essential source parameter that fundamentally controls hazard and risk. In this paper, we develop and demonstrate the capability of near-…
Fault volume digital twin to reproduce the full slip spectrum, scaling and statistical laws
M. Almakari, N. Kheirdast, C. Villafuerte +7
Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors.…
FASTDASH: An Implementation of 3D Earthquake Cycle Simulation on Complex Fault Systems Using the Boundary Element Method Accelerated by H-matrices
Jinhui Cheng, Harsha S. Bhat, Michelle Almakari +2
Fault systems have geometrically complex structures in nature, such as stepovers, bends, branches, and roughness. Many geological and geophysical studies have shown that the geomet…
