In this work we present a 3D Finite Difference numerical method to model the dynamic spontaneous propagation
of an earthquake rupture on planar faults in an elastic half-space. We implement the Tract...
Supershear transition due to a free surface in 3-D simulations of spontaneous dynamic rupture on vertical strike-slip faults
Supershear transition Earthquake rupture dynamics Earthquake source physics

Supershear rupture propagation has been inferred from seismic observations for natural faults and observed in laboratory experiments. We study the effect of the free surface on the transition of earth...
Three-dimensional boundary integral modeling of spontaneous earthquake sequences and aseismic slip
Three-dimensional boundary integral modeling earthquake sequences aseismic slip
2014/4/8
Fault processes involve complex patterns of seismic events and aseismic slip. This work develops a three-dimensional (3-D) methodology for simulating long-term history of spontaneous seismic and aseis...
Spectral element modeling of spontaneous earthquake rupture on rate and state faults: Effect of velocity-strengthening friction at shallow depths
Spectral element modeling spontaneous earthquake rupture rate and state faults:velocity-strengthening friction at shallow depths
2014/4/8
We develop a spectral element method (SEM) for simulating dynamic rupture on rate and state faults and use it to study how the rupture is affected by a shallow fault region of steady state velocity-st...
