Determination of Marine Sediment Strength at Depth from IODP Drilling Data, NanTroSEIZE Transect [PDF]

, 2019
Earthquakes and tsunami events pose significant threats to human life and property. Accordingly, the scientific community is developing an understanding of what controls fault strength and failure mechanics in order to develop physics-based models for ...

Engineering Specifications on LTBMS Telemetry System for NanTroSEIZE 3.5 km Riser Hole [PDF]

, 2020
The international project supported by the Integrated Ocean Drilling Program (IODP) started in autumn in 2007 to drill the area off Kii Peninsula, Japan. This area is one of the most active earthquake zones in the world.

Proceedings of the Integrated Ocean Drilling Program 348: NanTroSEIZE Stage 3: NanTroSEIZE Plate Boundary Deep Riser 3

, 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 ...

Subsurface Gaseous Hydrocarbons and Carbon Dioxide Recorded During the Trans‐Amazon Drilling Project (TADP) in the Acre Basin, Western Amazon

Geofluids, Volume 2025, Issue 1, 2025.
The Trans‐Amazon Drilling Project (TADP) drilled a sequence of claystones, siltstones, and sandstones in the Acre sedimentary basin, reaching a final depth of 923 m. This study characterizes the occurrence and compositional variation of light gaseous hydrocarbons detected using the online gas analysis (OLGA) monitoring system deployed during drilling ...

The Self‐Calibrating Tilt Accelerometer: A Method for Observing Tilt and Correcting Drift With a Triaxial Accelerometer

Earth and Space Science, Volume 11, Issue 11, November 2024.
Abstract We present observations from two field deployments of a calibrated tiltmeter that we name the Self‐Calibrating Tilt Accelerometer (SCTA). The tiltmeter is based upon a triaxial quartz crystal accelerometer; the horizontal channels measure tilt and are periodically rotated into the vertical to obtain a measurement of the acceleration of gravity.

Sediment Provenance Along the Middle Miocene‐Pleistocene Nankai Subduction Zone From Sediment Transport to Accretion: Implications for Stratigraphy in the Accretionary Prism

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 8, August 2024.
Abstract Based on U‐Pb dating of zircon crystals and petrographic analysis, this study provides new insights into the paleogeographic and accretion evolution along SW Japan. Our data are consistent with an older submarine fan identified from drilling in the Shikoku Basin (Kyushu Fan ∼14.7–12.2 Ma), having a mixed sand provenance from the paleo‐Yangtze ...

Frontal Thrust Ramp‐Up and Slow Earthquakes Due To Underthrusting of Basement High in the Nankai Trough

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 7, July 2024.
Abstract Recently, integrated geophysical‐geological surveys in the Nankai subduction zone in Japan have revealed that slow earthquakes repeatedly occur beneath the outer wedge of the forearc. During December 2020 to February 2021, clustered slow earthquakes propagated around the frontal thrust of the accretionary wedge.

Geometrical dependence on the stress and slip tendency acting on the subduction megathrust of the Nankai seismogenic zone off Kumano

Progress in Earth and Planetary Science, 2019
We assess the dependence of megathrust geometry near the updip edge of the Nankai seismogenic zone according to the slip tendency of the megathrust based on a reprocessed 3D PSDM seismic volume image and International Ocean Discovery Program (IODP ...
