متن کاملDynamics of a velocity strengthening fault region: Implications for slow earthquakes and postseismic slip
We consider the effect of permanent stress changes on a velocity strengthening rate-and-state fault, through numerical simulations and analytical results on 1D, 2D and 3D models. We show that slip transients can be triggered by perturbations of size roughly larger than Lb = Gdc/bσ, where G is the shear modulus, dc and b are respectively the characteristic slip distance and the coefficient of th...
متن کاملLaboratory observations of slow earthquakes and the spectrum of tectonic fault slip modes
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 discoveries of tremor, slow-slip and low-frequency earthquakes, are less understood. Theoretical models and sparse laboratory observations have pr...
متن کاملSlip weakening as a mechanism for slow earthquakes
Slow slip forms part of the spectrum of fault behaviour between stable creep and destructive earthquakes1,2. Slow slip occurs near the boundaries of large earthquake rupture zones3,4 and may sometimes trigger fast earthquakes2. It is thought to occur in faults comprised of rocks that strengthen under fast slip rates, preventing rupture as a normal earthquake, or on faults that have elevated por...
متن کاملSlow earthquakes, preseismic velocity changes, and the origin of slow frictional stick-slip.
Earthquakes normally occur as frictional stick-slip instabilities, resulting in catastrophic failure and seismic rupture. Tectonic faults also fail in slow earthquakes with rupture durations of months or more, yet their origin is poorly understood. Here, we present laboratory observations of repetitive, slow stick-slip in serpentinite fault zones and mechanical evidence for their origin. We doc...
