On the Thermodynamics of Subduction
Journal of Physical Oceanography, 1995 Abstract The thermodynamic processes attendant on the transfer of fluid between a surface mixed layer and a stratified thermocline beneath are discussed. For a parcel of fluid in the mixed layer to pass into the stratified thermocline—to subduct—it must be stratified by buoyancy input; this buoyancy can be supplied by local air–sea exchange and/or by ...

Quantifying continental collision dynamics for Alpine-style orogens
Frontiers in Earth Science, 2022 When continents collide, the arrival of positively buoyant continental crust slows down subduction. This collision often leads to the detachment of earlier subducted oceanic lithosphere, which changes the subsequent dynamics of the orogenic system ...

An Evaluation of Proposed Mechanisms of Slab Flattening in Central Mexico [PDF]
, 2010 Central Mexico is the site of an enigmatic zone of flat subduction. The general geometry of the subducting slab has been known for some time and is characterized by a horizontal zone bounded on either side by two moderately dipping sections.

On the initiation of subduction zones
pure and applied geophysics, 1989 Analysis of the relation between intraplate stress fields and lithospheric rheology leads to greater insight into the role that initiation of subduction plays in the tectonic evolution of the lithosphere. Numerical model studies show that if after a short evolution of a passive margin (time span a few tens of million years) subduction has not yet ...

Bathymetric Highs Control the Along-Strike Variations of the Manila Trench: 2D Numerical Modeling
Frontiers in Earth Science, 2022 The Manila Trench is located at the eastern boundary of the South China Sea (SCS). It develops through the subduction of the SCS beneath the Philippine Sea Plate (PSP) since the early Neogene, driven by the northwestern plate motion of the PSP.

Triggered seismicity associated with the 1990 Nicoya, Costa Rica, M-w=7.0 earthquake [PDF]
, 2009 The 25 March 1990 (M-w = 7.0) subduction megathrust earthquake that occurred offshore the Nicoya Peninsula, Costa Rica, produced a large number of aftershocks on the subduction plate interface as expected and preceded an unusual sequence of earthquakes ...

TerraceM-2: A Matlab® Interface for Mapping and Modeling Marine and Lacustrine Terraces
Frontiers in Earth Science, 2019 The morphology of marine and lacustrine terraces has been largely used to measure past sea- and lake-level positions and estimate vertical deformation in a wealth of studies focused on climate and tectonic processes.

What Controls Maximum Magnitudes of Giant Subduction Earthquakes?
Geochemistry, Geophysics, Geosystems, 2020 Giant earthquakes with magnitudes above 8.5 occur only in subduction zones. Despite the developments made in observing large subduction zone earthquakes with geophysical instruments, the factors controlling the maximum size of these earthquakes are still

Magmatism and tectonic evolution of West Antarctica
Dizhi lixue xuebao, 2021 West Antarctica is mainly composed of five distinct micro-continental blocks, namely Haag Nunataks, Antarctic Peninsula, Thurston Island, Marie Byrd Land and Ellsworth-Whitmore Mountains. In order to understand the geological evolution of West Antarctica,

Earth's rotation variability triggers explosive eruptions in subduction zones [PDF]
, 2015 The uneven Earth’s spinning has been reported to affect geological processes, i.e. tectonism, seismicity and volcanism, on a planetary scale. Here, we show that changes of the length of day (LOD) influence eruptive activity at subduction margins ...
