New 2010 Maule Aftershock Catalog Reveals Structure of the Deep Subduction Interface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract On 27 February 2010, a Mw 8.8 earthquake occurred near Maule in south‐central Chile. The subsequent rapid deployment of a dense network of seismic stations on land was able to capture the first year of its aftershock sequence. Here, we revisit this data set using picking Artificial Intelligence tools, a 3D velocity model of the region and ...

Complex anisotropy beneath the Peruvian flat slab from frequency-dependent, multiple-phase shear wave splitting analysis [PDF]

, 2013
Flat or shallow subduction is a relatively widespread global occurrence, but the dynamics remain poorly understood. In particular, the interaction between flat slabs and the surrounding mantle flow has yet to be studied in detail.

2D visco-elasto-plastic subduction models in the presence of a high density and viscosity continental block: a case study for the slab geometry beneath the Kii Peninsula, southwest Japan

Progress in Earth and Planetary Science
The Philippine Sea (PHS) plate embracing the Shikoku Basin subducts with a relatively young age varying between ~ 15 and 26 Ma. It exhibits a diversity of subduction styles along the Nankai Trough, from shallow beneath Shikoku and Chugoku regions to ...

Dynamic Evolution of Forearc Subsidence Controlled by Slab Geometry

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Several subduction zones worldwide present an enigmatic forearc topography and strain characterized by extension at a forearc ridge near the trench and shortening within a forearc valley located between the ridge and the magmatic arc. The development of this topography has been linked to progressive slab steepening, while strain patterns ...

Tectonic Tremor Reveals Slow Deformation Along the Antarctic–South American Subduction Zone

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Antarctic–South American subduction zone is among the least explored convergent margins and lacks documented large interplate earthquakes despite ongoing convergence. Here we report the discovery of tectonic tremor along this plate boundary using continuous seismic data.

Rheological control of Wadati-Benioff zone seismicity [PDF]

, 1988
Intermediate and deep focus earthquakes in Wadati-Benioff zones are thought to occur in the cold interiors of downgoing slabs which are significantly stronger than the warmer mantle.

Tectonic significance of changes in post-subduction Pliocene-Quaternary magmatism in the south east part of the Carpathian-Pannonian Region [PDF]

, 2010
The south-eastern part of the Carpathian–Pannonian region records the cessation of convergence between the European platform/Moesia and the Tisza–Dacia microplate.

Thermal Conductivity Profile in the Nankai Accretionary Prism at IODP NanTroSEIZE Site C0002: Estimations From High‐Pressure Experiments Using Input Site Sediments

Geochemistry, Geophysics, Geosystems, 2020
Depth profiles of sediment thermal conductivity are required for understanding the thermal structure in active seismogenic zones. During the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE), a scientific drilling project of the International Ocean

Interseismic deformation at the Nankai subduction zone and the Median Tectonic Line, southwest Japan [PDF]

Journal of Geophysical Research: Solid Earth, 2003
GPS velocities in the vicinity of the Nankai Trough, southwest Japan, were inverted into three components: interplate loading due to Nankai Trough subduction, deformation associated with deep slip on the Median Tectonic Line (MTL), and the residual rigid plate motion.

Field and Experimental Observations Show Elevated Shear Strength of Active Margin Sediments Requires Processes Beyond Normal Consolidation

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Near‐seafloor marine sediments on active margins have been shown to be stronger than those on passive margins. However, the reasons for this are not fully understood. To investigate the role of intrinsic properties, we performed resedimentation and oedometer tests and measured undrained shear strength, grain size, mineralogy, and plasticity on
