Direct assessment of the hydraulic structure of the plate boundary at the toe of the Nankai accretionary prism
SUMMARY The Nankai Trough is a locus of slow slip, low-frequency earthquakes, and large
magnitude (M w> 8) earthquakes. It is usually assumed that high pore pressure contributes …

The stabilizing effect of high pore-fluid pressure along subduction megathrust faults: Evidence from friction experiments on accretionary sediments from the Nankai …
Pore-fluid pressure is an important parameter in controlling fault mechanics as it lowers the
effective normal stress, allowing fault slip at lower shear stress. It is also thought to influence …
