Deformation Structures From Splay and Décollement Faults in the Nankai Accretionary Prism, SW Japan(IODP NanTroSEIZE Expedition 316): Evidence for Slow and Rapid Slip in Fault Rocks

Geochemistry, Geophysics, Geosystems, 2020
Drilling during IODP NanTroSEIZE Expedition 316 led to the recovery of cores from the basal décollement in the frontal part of the Nankai accretionary prism and from a splay fault branching from the décollement at 25‐km landward of the prism toe.

Rheology and Biostratigraphy of the Mariana Serpentine Muds Unravel Mud Volcano Evolution

Journal of Geophysical Research: Solid Earth, Volume 124, Issue 11, Page 10752-10776, November 2019., 2019
Abstract In late 2016, the IODP Expedition 366 drilled 21 holes on summits and flanks of three serpentinite mud volcanoes (SMVs) of the Mariana Forearc: Yinazao (Blue Moon), Fantangisña (Celestial), and Asùt Tesoru (Big Blue). The drilling reached the forearc sediments underneath the SMVs only at Site U1498 where, according to data from this study, the

Synthesis of the Laboratory Frictional Properties of a Major Shallow Subduction Zone: The Nankai Trough, Offshore SW Japan

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Nankai Trough has a long history of ≥Mw 8 earthquakes and associated tsunamis. It has been the focus of decades of research, including drilling, providing the opportunity to measure the laboratory frictional properties of shallow accretionary prism samples. We collate all available friction data from the Nankai Trough and correlate it with

Chemical and Noble Gas Isotope Compositions of Formation Gases from a 3 km Deep Scientific Borehole in the Koyna Seismogenic Zone, Western India

Geofluids, Volume 2019, Issue 1, 2019., 2019
A 3 km deep research borehole KFD1 was drilled in the Koyna reservoir‐triggered seismicity region, Western India, between December 2016 and May 2017. The 1967 M 6.3 Koyna earthquake had generated a NNE‐SSW trending surface fissure zone in the Nanel‐Donichawadi‐Kadoli sector. KFD1 is located ~5 km south of Kadoli along the trend of the Donichawadi fault

State of Stress Across Major Faults in the Nankai Subduction Zone Estimated From Wellbore Breakouts

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Quantifying the orientation and magnitude of stress at tectonically active margins and along major fault systems is integral to understanding the mechanics of faulting and earthquakes. Here we use data collected as part of the IODP (Integrated Ocean Drilling Program) Nankai Trough Seismogenic Zone Experiment to constrain in situ stress ...

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
