Stress orientations in subduction zones and the strength of subduction megathrust faults
Science, 2015Faults well oriented for failure A deck of cards will remain motionless while pressed on from above, but easily separates when sheared. Similarly, the ease by which geological faults rupture depends on the geometry of the fault relative to the size and direction of stress.

Subduction zones are where sediments, oceanic crust, and mantle lithosphere return to and reequilibrate with Earth's mantle. Subduction zones are interior expressions of Earth's 55,000 km of convergent plate margins and are the geodynamic system that builds island arcs.

Conventional structure data from orogenic belts can be related to events of lithospheric plate subduction regardless of the great difference in depth range of the compared sets. Thrust fabrics and rotation zone fabrics are diagnostic of the two possible orientations of vergenz with respect to subduction and of events of flip, i.e., reversal in dip of ...

Age-Dependent Subduction of Oceanic Lithosphere and the Rheology of Subducted Slabs
1983ABSTRACT On the basis of observational data and model calculations the temperature conditions at the depths of the deepest earthquake foci in subduction zones were determined. It is shown that a simple rheological model, in which the transition from elastic-brittle to plastic behaviour is temperature- and pressure-dependent, adequately explains the ...
