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.…
Depth Dependence of Coseismic Off-Fault Damage and its Effects on Rupture Dynamics
Roxane Ferry, Marion Y. Thomas, Harsha S. Bhat +1
Faults are complex systems embedded in an evolving medium fractured by seismic ruptures. This off-fault damage zone is shown to be thermo-hydro-mechano-chemically coupled to the ma…
Friction Laws and Numerical Modeling of the Seismic Cycle
M. Y. Thomas, H. S. Bhat
Earthquakes rank among the most destructive manifestations of the Earth's dynamics. Can they be predicted? This is often the first question students ask. To answer that right away:…
On the importance of 3D stress state in 2D earthquake rupture simulations with off-fault deformation
Louise Jeandet Ribes, Marion Y. Thomas, Harsha S. Bhat
During the last decades, many numerical models have been developed to investigate the conditions for seismic and aseismic slip. Those models explore the behavior of frictional faul…
Signature of transition to supershear rupture speed in coseismic off-fault damage zone
Jorge Jara, Lucile Bruhat, Marion Y. Thomas +8
Most earthquake ruptures propagate at speeds below the shear wave velocity within the crust, but in some rare cases, ruptures reach supershear speeds. The physics underlying the tr…
