Back to full interseismic plate locking decades after the giant 1960 Chile earthquake

Nature Communications, 2018
Great megathrust earthquakes arise from the sudden release of strain accumulated during centuries of interseismic plate convergence. Here, the authors reconstruct interseismic strain accumulation since the 1960 Chile earthquake, finding a transient ...

Subducting slabs: Jellyfishes in the Earth's mantle [PDF]

Geochemistry, Geophysics, Geosystems, 2010
The constantly improving resolution of geophysical data, seismic tomography and seismicity in particular, shows that the lithosphere does not subduct as a slab of uniform thickness but is rather thinned in the upper mantle and thickened around the transition zone between the upper and lower mantle. This observation has traditionally been interpreted as

The Impact of the Caroline Ridge Subduction on the Geomorphological Characteristics of Major Landforms in the Yap Subduction Zone

Journal of Marine Science and Engineering, 2022
The Caroline Ridge (CR) subduction underneath the Philippine Sea Plate brings complex morphotectonic characteristics to the Yap Subduction Zone (YSZ) compared to other normal intra-oceanic subduction systems.

Dynamics of intraoceanic subduction initiation: 1. Oceanic detachment fault inversion and the formation of supra-subduction zone ophiolites

, 2015
Subduction initiation is a critical link in the plate tectonic cycle. Intraoceanic subduction zones can form along transform faults and fracture zones, but how subduction nucleates parallel to mid-ocean ridges, as in e.g., the Neotethys Ocean during the ...

PALEOZOIC GRANITOID MAGMATISM OF THE URALS: THE REFLECTION OF THE STAGES OF THE GEODYNAMIC AND GEOCHEMICAL EVOLUTION OF A COLLISIONAL OROGEN

Геодинамика и тектонофизика, 2021
The Ural mobile belt is an intracontinental epioceanic orogen that has already gone through all stages of the geodynamic development. Igneous rocks formed during each stage are important indicators for understanding the evolution of this belt and ...

A numerical study of the dynamics of subduction [PDF]

, 1988
The mechanics and dynamics of subduction have been studied using 2-D finite element analysis. Two finite element formulations have been employed; one formulation for Newtonian viscous flow and one formulation for linear elasticity and viscoelasticity ...

Origin and consequences of western Mediterranean subduction, rollback, and slab segmentation

, 2014
The western Mediterranean recorded subduction rollback, slab segmentation and separation. Here we address the questions of what caused Oligocene rollback initiation, and how its subsequent evolution split up an originally coherent fore arc into circum ...

Pacific subduction control on Asian continental deformation including Tibetan extension and eastward extrusion tectonics

Nature Communications, 2019
The India-Asia collision has formed the highest mountains on Earth and is thought to account for extensive intraplate deformation in Asia. The prevailing explanation considers the role of the Pacific and Sunda subduction zones as passive during ...
