Growth of forearc highs and basins in the oblique Sumatra subduction system
Petroleum Exploration and Development, 2021 Based on structural deformation analysis in the oblique Sumatra subduction system, we review uplift mechanisms of the forearc high and formation of the forearc basin.

Understanding subduction infancy to mature subduction in Southwest Japan via the self-consistent formation of a weak slab interface [PDF]
Scientific Reports, 2023 The weak slab interface controls long-term subduction dynamics. A weak hydrous layer at the slab interface promotes mechanical decoupling between the forearc mantle and the subducting slab and converts a hot forearc mantle to a cold mantle.

Unraveling the diversity of Arc volcanism and deep low-frequency tremors in Southwest Japan from numerical modeling [PDF]
Scientific ReportsDifferences in slab dehydration and fluid transport influence the distribution of magmatism and deep low-frequency tremors in subduction zones. Southwest Japan, particularly Kyushu and Shikoku/Chugoku, exhibits significant along-arc variation in the ...

Reestimation of slab dehydration fronts in Kuril-Kamchatka using updated global subduction zone thermal structures [PDF]
iScience, 2023 Summary: Previous subduction thermal models are inconsistent with the values of forearc heat flow (50–140 mW/m2) and global P‒T conditions of exhumed rocks, both suggesting a shallow environment 200–300°C warmer than model predictions. Here, we revaluate

Normal Faulting Along the Kythira-Antikythira Strait, Southwest Hellenic Forearc, Greece
Frontiers in Earth Science, 2022 Upper-plate normal faults along forearcs often accumulate slip during >Mw 6 earthquakes. Such normal faults traverse the forearc of the Hellenic Subduction System (HSS) in Greece and are the focus of this study. Here, we use detailed field-mapping and

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The fate of fluids released from subducting slab in northern Cascadia [PDF]
Solid Earth, 2012 Large amounts of water carried down in subduction zones are driven upward into the overlying forearc upper mantle and crust as increasing temperatures and pressure dehydrate the subducting crust.
