Shallow Creep in the Leaky Stress Shadow of Locked Zones of Subduction Megathrust

Geophysical Research Letters
In some subduction zones such as Nankai, creeping of the shallow part of the megathrust in the stress shadow of deeper locked zones is detected by seafloor geodetic measurements and/or reflected by slow earthquakes (SEQs).

Subducted carbon weakens the forearc mantle wedge in a warm subduction zone [PDF]

Nature Communications
Subducting oceanic plates carry large amounts of carbon into the Earth’s interior. The subducted carbon is mobilized by fluid and encounters ultramafic rocks in the mantle wedge, resulting in changes to the mineral assemblage and mechanical properties of

Slow slip event within a gap between tremor and locked zones in the Nankai subduction zone [PDF]

Geophysical Research Letters, 2016
AbstractWe report on two small long‐term slow slip events (SSEs) within a gap between tremor and locked zones in the Nankai subduction zone, southwest Japan. The SSEs were detected by subtracting the steady state component and postseismic effects of large earthquakes from long‐term and high‐density Global Navigation Satellite System data.

Temperature limits to deep subseafloor life in the Nankai Trough subduction zone [PDF]

Science, 2020
Deep, hot, and more alive than we thought Marine sediments represent a massive microbial ecosystem, but we still do not fully understand what factors shape and limit life underneath the seafloor. Analyzing samples from a subduction zone off the coast of Japan, Heuer et al.

Fluid migration before and during slow earthquakes in the shallow Nankai subduction zone [PDF]

Journal of Geophysical Research: Solid Earth, 2021
Fluid migration in subduction zones is a key controlling factor of slow and megathrust earthquakes at plate boundaries. During the migration, seismic velocity and heterogeneous structures in its pathways may be temporarily varied, preferably triggering slow earthquakes.

Structural control and system-level behavior of the seismic cycle at the Nankai Trough

Earth, Planets and Space, 2020
The Nankai Trough in Southwest Japan exhibits a wide spectrum of fault slip, with long-term and short-term slow-slip events, slow and fast earthquakes, all associated with different segments down the plate interface.

Distribution of dehalogenation activity in subseafloor sediments of the Nankai Trough subduction zone [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2013
Halogenated organic matter buried in marine subsurface sediment may serve as a source of electron acceptors for anaerobic respiration of subseafloor microbes. Detection of a diverse array of reductive dehalogenase-homologous ( rdhA ) genes suggests that subseafloor organohalide-respiring ...

Sedimentary inputs to the Nankai subduction zone: The importance of dispersed ash [PDF]

Geosphere, 2018
We examine the importance of dispersed volcanic ash as a critical component of the aluminosilicate sediment entering the Nankai Trough, located south of Japan’s island of Honshu, via the subducting Philippine Sea plate. Multivariate statistical analyses of an extensive major, trace, and rare earth element data set from bulk sediment and discrete ash ...
