Direct structural evidence of Indian continental subduction beneath Myanmar
Nature Communications, 2020 Indian continental subduction can explain Cenozoic crustal deformation, magmatic activity and uplift of the Tibetan Plateau following the India-Asia collision.

BSGF - Earth Sciences Bulletin, 2020 The P–T evolution of a mafic eclogite sample from the Haut-Allier was studied in order to constrain the dynamic of the Variscan subduction in the eastern French Massif Central.

Melting of subducted sediments reconciles geophysical images of subduction zones
Nature Communications, 2021 AbstractSediments play a key role in subduction. They help control the chemistry of arc volcanoes and the location of seismic hazards. Here, we present a new model describing the fate of subducted sediments that explains magnetotelluric models of subduction zones, which commonly show an enigmatic conductive anomaly at the trenchward side of volcanic ...

Frontiers in Earth Science, 2021 Evaluating the transfer of stresses from megathrust earthquakes to adjacent segments is fundamental to assess seismic hazard. Here, we use a 3D forward model as well as GPS and seismic data to investigate the transient deformation and Coulomb Failure ...

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 ...

Middle to Late Miocene Contractional Deformation in Costa Rica Triggered by Plate Geodynamics [PDF]
, 2017 Contractional deformation in Costa Rica is usually attributed to the subduction of the aseismic Cocos Ridge. In this work, we review the evidences for contraction in the middle to late Miocene, prior to the arrival of the Cocos Ridge at the Middle ...

Seamount Subduction and Earthquakes [PDF]
Oceanography, 2010 Seamounts are ubiquitous features of the seafloor that form part of the fabric of oceanic crust. When a seamount enters a subduction zone, it has a major affect on forearc morphology, the uplift history of the island arc, and the structure of the downgoing slab.

Science Advances, 2020 Subduction initiation at weakened passive continental margin could be induced by lateral propagation of existing subduction zones. Understanding the conditions for forming new subduction zones at passive continental margins is important for understanding

Boninite and Harzburgite from Leg 125 (Bonin-Mariana Forearc): A Case Study of Magma Genesis during the Initial Stages of Subduction [PDF]
, 1992 Holes drilled into the volcanic and ultrabasic basement of the Izu-Ogasawara and Mariana forearc terranes during Leg 125 provide data on some of the earliest lithosphere created after the start of Eocene subduction in the Western Pacific.

Frontiers in Marine Science, 2022 Motivated by the recurrent formation of eddies in the eastern upwelling areas, we examine cross-basin connectivity that is promoted by coherent, long-lived and long-propagating mesoscale eddies in the Atlantic Ocean.
