Self-healing slip pulses in dynamic rupture models due to velocity-dependent strength Self-healing slip pulses in dynamic rupture models due to velocity-dependent strength
Seismological observations of short slip duration on faults (short rise time on seismograms) during earthquakes are not consistent with conventional crack models of dynamic rupture and fault slip. In these models, the leading edge of rupture stops only when a strong region is encountered, and slip at an interior point ceases only when waves from the stopped edge of slip propagate back to...

Implications of Coulomb plasticity for the velocity dependence of experimental faults Implications of Coulomb plasticity for the velocity dependence of experimental faults
Simulated fault gouges often deform more stably than initially bare surfaces of the same composition. It is important to understand why the sliding stability is enhanced because the presence of gouge on natural faults may have the same effect as seen in experiments, and thus explain the absence of earthquakes at shallow depths. Gouge stabilization in experiments has been attributed to...
