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.

Do Trench Sediments Affect Great Earthquake Occurrence in Subduction Zones? [PDF]
Pure and Applied Geophysics, 1989 Seismic energy release is dominated by the underthrusting earthquakes in subduction zones, and this energy release is further concentrated in a few subduction zones.

Subduction zones are characterized by multiple behaviors, dynamics, or geometries. Most of them results from the complex interplay between various parameters. In this article, we define the most common parameters used by scientists and then mention the studies where (set of) parameters are tested empirically, or experimentally.

Creeping subduction zones are weaker than locked subduction zones
Nature Geoscience, 2017Faults that are fully or partially locked pose the greatest seismic hazard because they accumulate stress that can then be released in large earthquakes. In contrast, other faults continuously creep. The creeping versus locked behaviour is probably related to the frictional properties of the fault and the effective normal stress on the fault, but it is

Viscosity of Fluids in Subduction Zones
Science, 2004The viscosities of aqueous fluids with 10 to 80 weight percent dissolved silicates have been measured at 600° to 950°C and 1.0 to 2.0 gigapascals by in situ observation of falling spheres in the diamond anvil cell. The viscosities at 800°C range from 10 –4 to 10 0.5 pascal seconds.

Subduction is a major process that plays a first-order role in the dynamics of the Earth. The sinking of cold lithosphere into the mantle is thought by many authors to be the most important source of energy for plates driving forces. It also deeply modifies the thermal and chemical structure of the mantle, producing arc volcanism and is responsible for

Fluid Processes in Subduction Zones
Science, 1990Fluids play a critical role in subduction zones and arc magmatism. At shallow levels in subduction zones (<40 kilometers depth), expulsion of large volumes of pore waters and CH 4 -H 2 O fluids produced by diagenetic and low-grade metamorphic reactions affect the thermal and rheological ...
