Geochemistry of continental subduction-zone fluids

Earth, Planets and Space, 2014
The composition of continental subduction-zone fluids varies dramatically from dilute aqueous solutions at subsolidus conditions to hydrous silicate melts at supersolidus conditions, with variable concentrations of fluid-mobile incompatible trace ...

Earthquake Relocation Using Double Difference Method for 2D Modelling of Subducting Slab and Back Arc Thrust in West Nusa Tenggara

Jurnal Penelitian Fisika dan Aplikasinya, 2018
West Nusa Tenggara is classified into earthquake prone zone as it is located between subduction and back arc thrust earthquake sources. Accurate hypocenter determination in this area is necessary for strong motion calculation and earthquake source zone ...

Terrane Collision‐Induced Subduction Initiation: Mode Selection and Implications for Western Pacific Subduction System

Geochemistry, Geophysics, Geosystems
In the regime of plate tectonics, the subduction of an oceanic plate generally terminates with the collision and accretion of continental terranes. Then, a new subduction zone may form in the neighboring oceanic plates, which is defined as the terrane ...

Evolving Subduction Zone Thermal Structure Drives Extensive Forearc Mantle Wedge Hydration

AGU Advances
Hydration of the subduction zone forearc mantle wedge influences the downdip distribution of seismicity, the availability of fluids for arc magmatism, and Earth's long term water cycle.

Analysis of Stress Drop Variations in Fault and Subduction Zones of Maluku and Halmahera Earthquakes in 2019

Jurnal Penelitian Fisika dan Aplikasinya, 2019
The amount of stress released by an earthquake can be calculated with a stress drop, the stress ratio before and after an earthquake where the stress accumulated in a fault or a subduction zone is immediately released during an earthquake. The purpose of

Subduction Zone Magmas

, 2013
The importance of subduction zones, which are major sites of earthquakes, mountain building, and basalt–andesite–rhyolite volcanism, was nicely presented by Stern (Rev Geophys 40:1012, 2002): “Subduction zones are also our planet’s largest recycling system.

Weak asthenosphere of Sumatran backarc revealed by long postseismic geodetic records

Communications Earth & Environment
The viscosity of Earth’s asthenosphere regulates plate motion and surface deformation. Assessing asthenosphere rheology in subduction-zone backarcs is as crucial as in forearc and arc regions for understanding subduction dynamics.

Flexural and Membrane Stresses in Doubly Curved Subducting Slabs

Geochemistry, Geophysics, Geosystems
A subducting slab is a thin doubly curved shell with a complex shape that deforms in interaction with the surrounding mantle. Such a shell can deform in two distinct ways: by in‐plane stretching and shear (“membrane” deformation) and by bending and ...
