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

Subduction Zones: A Short Review
, 2023 Subduction zones are locations on Earth where the oceanic material of one tectonic plate dives below the material (oceanic or continental) of another tectonic plate into the mantle. They are the most complex and dramatic tectonic features on our home planet and have been the subject of intense investigations, some of which pre-date the advent of the ...

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 ...

Fluid‐Mediated Mass Transfer Between Mafic and Ultramafic Rocks in Subduction Zones
Geochemistry, Geophysics, Geosystems, 2022 Metasomatic reaction zones between mafic and ultramafic rocks exhumed from subduction zones provide a window into mass‐transfer processes at high pressure.

Frontiers in Earth Science, 2022 The potential mechanisms that drive the behavior of subducted oceanic plates at the 660-km discontinuity are subject to debate. Here we conduct logistic regression analysis and model selection to determine the key subduction-zone parameters in natural ...

The importance of talc and chlorite ‘‘hybrid’’ rocks for volatile recycling through subduction zones; evidence from the high-pressure subduction melange of New Caledonia [PDF]
, 2008 The transfer of fluid and trace elements from the slab to the mantle wedge cannot be adequately explained by simple models of slab devolatilization. The eclogite-facies melange belt of northern New Caledonia represents previously subducted oceanic crust ...

Seismic Assessments of the Hikurangi and Aleutian-Alaska Subduction Zones [PDF]
, 2023 Subduction zones around the world indicate remarkably diverse and complex systems. In this dissertation, I will focus on the seismic characteristics of two subduction zones: the Hikurangi Subduction Zone (HSZ) and the Aleutian-Alaska Subduction Zone ...

Deformation and transformation of subduction zone hydrous minerals and rocks
, 2021 International audienceHydrous minerals condition water transport and location down to depths in the earth, and are crucial to the overall dynamics in subduction zones. Their presence, destabilisation or growth, can affect the long- or short-term coupling

Geosciences, 2022 We discussed the peculiarities of the seismic cycle in Aleutian subduction zone, characterized by an oblique subduction setting. It was shown that the orientation of the plate convergence vector relative to the subduction zone axis can have a significant
