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

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.

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.

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.

Progress in Earth and Planetary Science, 2018 Ocean drilling in the Nankai Trough forearc suggests a new scenario for the evolution of the Nankai subduction zone. Continuous subduction since the Late Cretaceous has been a common tectonic scenario, although the plate subduction was transferred from ...

Bridging the gap between low-frequency and very-low-frequency earthquakes
Earth, Planets and Space, 2020 Slow earthquakes that are observed in the > 1 Hz frequency band are called tectonic tremor or low-frequency earthquakes (LFEs) and those in the 0.01–0.10 Hz band are called very-low-frequency earthquakes (VLFEs).

Distribution and depth of bottom-simulating reflectors in the Nankai subduction margin
Earth, Planets and Space, 2018 Surface heat flow has been observed to be highly variable in the Nankai subduction margin. This study presents an investigation of local anomalies in surface heat flows on the undulating seafloor in the Nankai subduction margin.
