We emphasize the importance of marine silicate weathering (MSiW) reactions in anoxic
sediment as fundamental in generating alkalinity and cations needed for carbonate …

Twelve submarine mud volcanoes (MV) in the Kumano forearc basin within the Nankai
Trough subduction zone were investigated for hydrocarbon origins and fluid dynamics. Gas …

Strength and slip behaviors of subduction megathrusts are controlled by the physical
properties and stress state not only of the fault zones themselves but also the adjacent wall …

Quantifying the orientation and magnitude of tectonic stresses is essential toward
understanding deformation and faulting in subduction zones. However, constraints on in situ …

We investigate the chlorine isotope disequilibrium between chlorides in pore fluids and
chlorides in seawater and infer its consequences for chlorine isotope exchange between …

The hydromechanical properties of accreted and underthrust sediments are key parameters
controlling the mechanics of earthquakes and the development of fluid pressure in …

The mechanical behavior of the plate boundary fault zone is of paramount importance in
subduction zones, because it controls megathrust earthquake nucleation and propagation …

We identified widely distributed thrust and strike-slip faults within subducting oceanic crust in
the Nankai Trough, southeast of the Kii Peninsula, Japan, on the basis of 2D and 3D seismic …

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 …

Nineteen whole‐round core samples from the Nankai accretionary prism (IODP Expeditions
315, 316, and 333) from a depth range of 28–128 m below sea floor were experimentally …
