Modeling the dynamic rupture propagation on heterogeneous faults with rate- and state-dependent friction
dynamic rupture fault constitutive law fault friction stress heterogeneities
2015/9/10
We investigate the effects of non-uniform distribution of constitutive parameters on the dynamic propagation of
an earthquake rupture. We use a 2D finite difference numerical method and we assume tha...
Scaling of small repeating earthquakes explained by interaction of seismic and aseismic slip in a rate and state fault model
Scaling small repeating earthquakes explained by interaction seismic aseismic slip in a rate state fault model
2014/4/8
Because of short recurrence times and known locations, small repeating earthquakes present a rare predictable opportunity for detailed field observations. They are used to study fault creeping velocit...
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...

The order of weighted sum of noise sequence for stochasticsystem is estimated by using limit theory in probability. Then thedivergence rates of state of unstable AR system driven by noise ofmartingale...
Variability of earthquake nucleation in continuum models of rate-and-state faults and implications for aftershock rates
Variability earthquake nucleation continuum models rate-and-state faults implications for aftershock rates
2014/4/8
Using two continuum models of rate-and-state faults, one with a weaker patch and the other with rheological transition from steady state velocity-weakening to velocity-strengthening friction, we simul...
