A review of the seismotectonics of the Makran Subduction Zone as a baseline for Tsunami Hazard Assessments

Geoscience Letters, 2019
The Makran Accretionary Wedge (900 km across) is a consequence of northward subduction of the oceanic part of the Arabian Plate beneath the Lut and Afghan blocks in the northwestern Indian Ocean.

Changing Sources of Magma Generation Beneath Intra-Oceanic Islands Arcs: An Insight From the Juvenile Kohistan Island Arc, Pakistan Himalaya

, 2006
The Kohistan arc, situated in the Pakistan Himalaya, is a Cretaceous intraoceanic island arc which was initiated during the northward movement of the Indian Plate. The arc was sutured to Asia at ca. 100 Ma.

Generation of normal and adakite-like calc-alkaline magmas in a non-subductional environment: An Sr-O-H isotopic study of the Apuseni Mountains neogene magmatic province, Romania

, 2007
Neogene magmatism in the Apuseni Mountains of Romania was active between 15 and 7 Ma, with an isolated final eruption at 1.6 Ma. Several groups of magmatic rocks can be distinguished in the province on the basis of ages, trace elements and isotopic ...

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 ...

Rheological control of Wadati-Benioff zone seismicity

, 1988
Intermediate and deep focus earthquakes in Wadati-Benioff zones are thought to occur in the cold interiors of downgoing slabs which are significantly stronger than the warmer mantle.

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

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 ...

The metamorphic evolution of an ancient accretionary prism in the southern zone of the Damara Belt in Namibia

, 2013
The Southern Zone of the Damara Belt in central Namibia has an apparent stratigraphic thickness that exceeds 100 km and is comprised of highly strained, metamorphosed clastic sedimentary rocks that are intercalated with slices of metamorphosed basalt and

How weak is the subduction zone interface?

, 2015
Several lines of evidence suggest that subduction zones are weak and that the unique availability of water on Earth is a critical factor in the weakening process. We have evaluated the strength of subduction zone interfaces using two approaches: (i) from
