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...
متن کاملCreep events slip less than ordinary earthquakes
[1] We find that slow seismic events have smaller fault slips compared to ordinary earthquakes with similar dimensions. For ordinary earthquakes, the ratio of slip to fault length is largely consistent, yet the physical controls on this ratio are unknown. Recently discovered slow slip or creep events in which faults move quasi-statically over periods of days to years shed new light on this old ...
متن کاملSlow-slip evolves into megathrust earthquakes in 2D numerical simulations
[1] Slow slip events (SSE) in many subduction zones incrementally stress the adjacent locked megathrust, suggesting that they could potentially either trigger or evolve into damaging earthquakes. We explore this with 2D quasidynamic simulations with rate-state friction, dilatancy, and coupled 1D pore-fluid and heat transport. Steady-state weakening friction allows transient slip to nucleate, bu...
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...
