A Symmetry-based Method for Kinematic Analysis of Large-slip Brittle Fault Zones
We apply a symmetry-based, statistical method for kine matic analysis of mesoscale fault-zone structures to resolve the trans port directions for the Rosario fault zone and Lopez StructuralCom plex in the San Juan Islands. Both moderately dipping fault zones accommodated large amounts of Late Cretaceous slip ( > 30 km), but the transport direction of nappes overlying these fault zones is con...
متن کاملDeconvoluting complex structural histories archived in brittle fault zones
Brittle deformation can saturate the Earth's crust with faults and fractures in an apparently chaotic fashion. The details of brittle deformational histories and implications on, for example, seismotectonics and landscape, can thus be difficult to untangle. Fortunately, brittle faults archive subtle details of the stress and physical/chemical conditions at the time of initial strain localizatio...

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 کاملDilatant strengthening as a mechanism for slow slip events
[1] The mechanics of slow slip events (SSE) in subduction zones remain unresolved. We suggest that SSE nucleate in areas of unstable friction under drained conditions, but as slip accelerates dilatancy reduces pore pressure p quenching instability. Competition between dilatant strengthening and thermal pressurization may control whether slip is slow or fast. We model SSE with 2‐D elasticity, ra...
