Paleo-stress orientations and magnitudes from triaxial testing and stress inversion analysis in Nankai accretionary prism sediments

Progress in Earth and Planetary Science, 2019
Combined knowledge on the magnitude as well as the orientation of paleo-stress is usually not given. Based on drilling investigations and laboratory experiments, we are able to provide both, constraints on paleo-stress magnitude as well as orientation in

Linking Faults, Fractures, and Clay Mineral Occurrence With Fluid Transport in the Accretionary Prism of the Nankai Trough, Japan

Geochemistry, Geophysics, Geosystems, Volume 20, Issue 11, Page 4599-4612, November 2019., 2019
Abstract The interpretation of logging while drilling resistivity oriented images and geophysical logs from Hole C0002 drilled during the International Ocean Discovery Program (IODP) Expeditions 338 and 348 of the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) project revealed a complex structure of the accretionary prism characterized by ...

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

NanTroSEIZE Stage 3: NanTroSEIZE Plate Boundary Deep Riser 3 Expedition 348

, 2015
The Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) is a multidisciplinary investigation of fault mechanics and seismogenesis along subduction megathrusts and includes reflection and refraction seismic imaging, direct sampling by drilling, in situ measurements, and long-term monitoring in conjunction with laboratory and numerical modeling ...

Heat flow estimated from BSR and IODP borehole data: Implication of recent uplift and erosion of the imbricate thrust zone in the Nankai Trough off Kumano

Geochemistry, Geophysics, Geosystems, 2011
Heat flow values were estimated in the Nankai Trough fore‐arc slope region off Kii Peninsula from the Bottom‐Simulating Reflector (BSR) and other data obtained during IODP Expeditions 315 and 316.

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
