To better understand the distribution of three dimensional stress states in the Nankai
subduction zone, southwest Japan, we review various stress-related investigations carried …

3. Determination of horizontal stress within the deep interior of the inner wedge; 4.
Investigation of the mechanical state and behavior of the formation; and 5. Characterization …

Breakouts observed in a vertical borehole (C0002A) drilled through two major tectonic
sedimentary formations consisting of forearc basin (upper) and accretionary prism (lower) …

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 …

This study presents a method of two‐dimensional scanning electron microscope image
analysis that directly quantifies microporosity abundance in clay‐rich, fine‐grained …

Natural gas hydrate in sand sediments can increase both the measured compressional
velocity and resistivity. The same geophysical signatures occur, however, in low‐porosity …

Pore waters were taken from core sediments of Sites C0001, C0004, and C0008 on the
landward slope of the Nankai Trough and Site C0002 in the forearc basin of the Nankai …

To reveal the stress state within the Kumano basin, which overlies the Nankai accretionary
prism, we estimated seismic anisotropy from walkaround vertical seismic profiling (VSP) …

We constrain the state of stress to 2 km below seafloor in the Nankai accretionary prism at
the Integrated Ocean Drilling Program (IODP) site C0002F, southwest Japan, based on …

This paper presents a complete set of in situ stress calculations for depths of 200–1400
meters below seafloor at Integrated Ocean Drilling Program (IODP) Site C0002, near the …
