Splay Fault Permeability Governs Fluid–Structure Interaction in Accretionary Wedges

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Interactions between upper plate deformation and plate interface seismicity in subduction zones remain poorly understood, but growing evidence indicates that fluid flow along splay faults modulates upper‐plate faulting. Field observations from two exhumed splay faults define end‐member scenarios where impermeable faults trap fluids in their ...

Moment tensor inversion of the 2016 southeast offshore Mie earthquake in the Tonankai region using a three-dimensional velocity structure model: effects of the accretionary prism and subducting oceanic plate

Earth, Planets and Space, 2018
The southeast offshore Mie earthquake occurred on April 1, 2016 near the rupture area of the 1944 Tonankai earthquake, where seismicity around the interface of the Philippine Sea plate had been very low until this earthquake.

Low‐Frequency Ocean Waves Triggered by Tropical Cyclones via Seafloor Distributed Acoustic Sensing

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Propagation of low‐frequency ocean waves, including infragravity (IG) and internal waves, affect ocean dynamics and energy transfer within marine environments. IG waves are long‐period ocean surface waves that can propagate long distances across the ocean and impact the coastlines and deep ocean, while internal waves are buoyancy‐driven ...

Deformation of the Nankai Trough inner accretionary prism: The role of inherited structures [PDF]

, 2016
Accretionary prisms commonly grow seaward, with the strata of the inner prism consisting of older, previously accreted outer prism rocks overlain by thick fore-arc basin strata.

Spatiotemporal Characteristics of Tectonic Tremors in California

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract California, as a transform plate boundary, provides a distinctive tectonic setting and an ideal natural laboratory for investigating tectonic tremors and the slow deformation associated with plate motion. By analyzing continuous seismic records across multiple stations with an envelope correlation method, we identified ∼83,000 tremor events ...

Revisiting interseismic deformation in Nankai: focusing on slip-deficit accumulation in the ETS zone and comparison with Cascadia

Earth, Planets and Space
Various stress-releasing phenomena, such as episodic tremor and slip (ETS) and low-frequency earthquakes, occur at the downdip seismogenic zone in southwest Japan.

Low-grade metamorphism around the down-dip limit of seismogenic subduction zones: Example from an ancient accretionary complex in the Shimanto Belt, Japan [PDF]

, 2011
International audienceReactions involving clay minerals during low-grade metamorphism at the depth of an ancient accretionary complex in the Shimanto Belt, Kyushu, Japan, were studied by integrated transmission electron microscopy-energy dispersive X-ray

Facies analysis provides new insights into event bed deposition in a hadal trench environment

Sedimentology, Volume 73, Issue 2, Page 441-477, February 2026.
ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...

Determination of stress state in deep subsea formation by combination of hydraulic fracturing in situ test and core analysis: A case study in the IODP Expedition 319

, 2013
[1] In situ test of hydraulic fracturing (HF) provides the only way to observe in situ stress magnitudes directly. The maximum and minimum horizontal stresses, SHmax and Shmin, are determined from critical borehole pressures, i.e., the reopening pressure
