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 ...

The impact of faulting complexity and type on earthquake rupture dynamics
Communications Earth & Environment, 2022 Earthquakes on thrust faults display a higher double couple component relative to those on strike-slip and normal faults which may be a result of more mature fault zone structure, according to a statistical analysis of global earthquake moment ...

Uncertainty quantification of dynamic earthquake rupture simulations [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021 We present a tutorial demonstration using a surrogate-model based uncertainty quantification (UQ) approach to study dynamic earthquake rupture on a rough fault surface. The UQ approach performs model calibration where we choose simulation points, fit and validate an approximate surrogate model or emulator, and then examine the ...

The Dynamics of Elongated Earthquake Ruptures [PDF]
Journal of Geophysical Research: Solid Earth, 2019 AbstractThe largest earthquakes propagate laterally after saturating the fault's seismogenic width and reach large length‐to‐width ratiosL/W. Smaller earthquakes can also develop elongated ruptures due to confinement by heterogeneities of initial stresses or material properties. The energetics of such elongated ruptures is radically different from that

Simultaneous Rupture Propagation Through Fault Bifurcation of the 2021 Mw7.4 Maduo Earthquake
Geophysical Research Letters, 2022 Fault geometric complexity plays a critical role in earthquake rupture dimension. Fault bifurcations are commonly observed in earthquake geology, yet, robust kinematic rupture processes on bifurcated fault branches are largely missing, limiting our ...

Rupture-dependent breakdown energy in fault models with thermo-hydro-mechanical processes [PDF]
Solid Earth, 2020 Substantial insight into earthquake source processes has resulted from considering frictional ruptures analogous to cohesive-zone shear cracks from fracture mechanics.

Strike-slip fault terminations at seismogenic depths : the structure and kinematics of the Glacier Lakes fault, Sierra Nevada United States [PDF]
, 2008 Structural complexity is common at the terminations of earthquake surface ruptures; similar deformation may therefore be expected at the end zones of earthquake ruptures at depth.
