IODP Expedition 333: Return to Nankai Trough Subduction Inputs Sites and Coring of Mass Transport Deposits [PDF]

Scientific Drilling, 2012
Integrated Ocean Drilling Program (IODP) Expedition 333 returned to two sites drilled during IODP Expedition 322 on the ocean side of the Nankai Trough to pursue the characterization of the inputs to the Nankai subduction and seismogenic zone, as part of

NanTroSEIZE: The IODP Nankai Trough Seismogenic Zone Experiment [PDF]

Scientific Drilling, 2006
The IODP Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) will, for the fi rst time ever, attempt to drill into, sample, and instrument the seismogenic portion of a plate-boundary fault or megathrust within a subduction zone.

The First D/V Chikyu IODP Operations: Successful Logging and Coring During NanTroSEIZE Stage 1 Expeditions [PDF]

Scientific Drilling, 2008
The Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) is a multi-expedition IODP drilling project aimed at drilling, coring, logging, and instrumenting the seismogenic zone of an active subduction margin , in a region thought to generate megathrust

Temporal variation in seismic moment release rate of slow slips inferred from deep low-frequency tremors in the Nankai subduction zone

Earth, Planets and Space, 2020
We examined seismic moment release rates as estimated from deep low-frequency tremors at episodic tremor and slip (ETS) zones on the plate interface in the Nankai subduction zone.

Rapid metabolism fosters microbial survival in the deep, hot subseafloor biosphere

Nature Communications, 2022
In the deep sedimentary biosphere, 80 °C has been proposed as an upper thermal barrier for life. Using a suite of radiotracer experiments, this study reports active methanogenic and sulfate-reducing microbial populations with high cell-specific metabolic

Development of a detection method for short-term slow slip events using GNSS data and its application to the Nankai subduction zone

Earth, Planets and Space, 2022
Using global navigation satellite system (GNSS) data to detect millimeter-order signals of short-term slow slip events (S-SSEs) and to estimate their source parameters, especially duration, is challenging because of low signal-to-noise ratio.

Temporal change in seismic velocity associated with an offshore M W 5.9 Off-Mie earthquake in the Nankai subduction zone from ambient noise cross-correlation

Progress in Earth and Planetary Science, 2018
The Nankai subduction zone off the Kii Peninsula, Japan, has a large potential to generate megathrust earthquakes in the near future. To investigate the temporal variation of stress or strain in the Nankai subduction zone, we estimated the temporal ...

Crustal resistivity structure around the Nankai subduction zone

BUTSURI-TANSA(Geophysical Exploration), 2005
The forearc crust along the Nankai Trough is characterized as an accretionary prism. The unconsolidated sediments on the subducting Philippine Sea plate are underplated to the southwest Japan arc, so that large amount of fluid is supplied to the accretionary prism.

Sporadic low-velocity volumes spatially correlate with shallow very low frequency earthquake clusters

Nature Communications, 2017
In the Nankai subduction zone a low-velocity zone (LVZ) has been detected. Here, the authors present shear wave velocity profiles to show that low frequency earthquakes correlate with the distribution of the LVZ in the Nankai subduction zone.

Tidal sensitivity of tectonic tremors in Nankai and Cascadia subduction zones [PDF]

Journal of Geophysical Research: Solid Earth, 2015
AbstractTectonic tremors in subduction zones, which result from slip at the deep plate interface, are known to exhibit a 12.4 h periodicity in their activity, due to tidal influence. Because tidal stress can be calculated quantitatively, the response of the plate interface can yield quantitative information about its frictional property.
