A transdisciplinary and community-driven database to unravel subduction zone initiation [PDF]

open access: yesNature Communications, 2020
Despite numerous advances in our understanding of subduction since the theory of plate tectonics was established, the mechanisms of subduction zone initiation remain highly controversial.

Uncovering and quantifying the subduction zone sulfur cycle from the slab perspective. [PDF]

open access: yesNat Commun, 2020
Sulfur belongs among H2O, CO2, and Cl as one of the key volatiles in Earth’s chemical cycles. High oxygen fugacity, sulfur concentration, and δ34S values in volcanic arc rocks have been attributed to significant sulfate addition by slab fluids.

Illuminating subduction zone rheological properties in the wake of a giant earthquake. [PDF]

open access: yesSci Adv, 2019
We invert postseismic geodetic data to reveal subduction zone mechanical properties following a megathrust earthquake in Chile. Deformation associated with plate convergence at subduction zones is accommodated by a complex system involving fault slip and

Subduction initiation terranes exposed at the front of a 2 Ma volcanically-active subduction zone

open access: yesEarth and Planetary Science Letters, 2019
The development of ideas leading to a greater understanding of subduction initiation is limited by the scarcity of present-day examples. Furthermore, the few examples identified so far unfortunately provide few insights into the nature of magmatism at ...

Control of slab tears and slab flat wedging on volcanism in the Alaska subduction zone [PDF]

open access: yesScientific Reports
Multistage plate subduction plays a crucial role in magmatism; however, the mechanisms by which deep geodynamic processes govern volcanism in the Alaska subduction zone remain controversial. Using numerous travel-time data from several seismic arrays, we

Slab Temperature Evolution Over the Lifetime of a Subduction Zone

open access: yesGeochemistry Geophysics Geosystems, 2021
The thermal evolution of subducting slabs controls a range of subduction processes, yet we lack a robust understanding of how thermal structure develops over a subduction zone's lifetime. We investigate the time‐dependence of slab thermal structure using

Features of the Largest Earthquake Seismic Cycles in the Western Part of the Aleutian Subduction Zone

open access: yesGeosciences, 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

Paleotsunamis on the Southern Hikurangi Subduction Zone, New Zealand, Show Regular Recurrence of Large Subduction Earthquakes

open access: yesThe Seismic Record, 2021
Geological records of subduction earthquakes, essential for seismic and tsunami hazard assessment, are difficult to obtain at transitional plate boundaries, because upper-plate fault earthquake deformation can mask the subduction zone signal.

Subduction Duration and Slab Dip [PDF]

open access: yes, 2020
The dip angles of slabs are among the clearest characteristics of subduction zones, but the factors that control them remain obscure. Here, slab dip angles and subduction parameters, including subduction duration, the nature of the overriding plate, slab
