Stability of pulse-like earthquake ruptures [PDF]
, 2019 Pulse-like ruptures arise spontaneously in many elastodynamic rupture simulations and seem to be the dominant rupture mode along crustal faults. Pulse-like ruptures propagating under steady-state conditions can be efficiently analysed theoretically, but ...

Role of Fluid Injection on Earthquake Size in Dynamic Rupture Simulations on Rough Faults
Geophysical Research Letters, 2020 An outstanding question for induced seismicity is whether the volume of injected fluid and/or the spatial extent of the resulting pore pressure and stress perturbations limit rupture size.

Landers 1992 "reloaded": Integrative dynamic earthquake rupture modeling [PDF]
Journal of Geophysical Research: Solid Earth, 2018 AbstractThe 1992 Mw 7.3 Landers earthquake is perhaps one of the best studied seismic events. However, many aspects of the dynamics of the rupture process are still puzzling, for example, the rupture transfer between fault segments. We present 3‐D spontaneous dynamic rupture simulations, incorporating the interplay of fault geometry, topography, 3‐D ...

Recent Milestones in Unraveling the Full-Field Structure of Dynamic Shear Cracks and Fault Ruptures in Real-Time: From Photoelasticity to Ultrahigh-Speed Digital Image Correlation [PDF]
, 2020 The last few decades have seen great achievements in dynamic fracture mechanics. Yet, it was not possible to experimentally quantify the full-field behavior of dynamic fractures, until very recently.

Seismic characteristics of supershear and sub‐Rayleigh earthquakes: Implication from simple cases
Geophysical Research Letters, 2017 Numerous investigations of supershear earthquakes make a conclusion that a supershear earthquake produces a seismic shock wave on the ground that may increase the resulting destruction. We investigate a supershear rupture promoted by the free surface and

Laboratory observations of slow earthquakes and the spectrum of tectonic fault slip modes [PDF]
, 2016 Slow earthquakes represent an important conundrum in earthquake physics. While regular earthquakes are catastrophic events with rupture velocities governed by elastic wave speed, the processes that underlie slow fault slip phenomena, including recent ...

Rupture dynamics of flat colloidal films
Physical Review Fluids, 2023 Here, we report experimental results on the rupture of flat colloidal films over a large range of volume fractions, 0.00 $\le ϕ\le$ 0.47. The films are formed using a constant fluid volume, ruptured with a needle, and recorded using a high-speed camera.

A physical model for widespread near‐surface and fault zone damage induced by earthquakes
Geochemistry, Geophysics, Geosystems, 2008 I present a rigorous unifying interpretation of the well‐documented widespread near‐surface and fault zone damage induced by earthquakes by simulating three‐dimensional dynamic rupture propagation on a vertical strike‐slip fault.
