A b map implying the first eastern rupture of the Nankai Trough earthquakes [PDF]

Nature Communications, 2018
Earthquakes generated from the Nankai Trough have caused much devastation over the years. Here, the authors present a b-value map for the Nankai Trough zone, where the Eastern part of the trough has lower b-values than the West, which may help to explain

Topography of the subducting basement throughout the entire Nankai Trough [PDF]

Scientific Reports
The heterogeneous distributions of large and slow earthquakes in subduction zones are caused by multiple uncertain conditions in the source regions, and the basement topography is considered one of the major controlling factors.

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

Numerical modeling of subduction and evaluation of Philippine Sea Plate tectonic history along the Nankai Trough [PDF]

Scientific Reports, 2023
The subduction of the Philippine Sea (PHS) plate along the Nankai Trough in in southwest Japan is a relatively recent process compared with subduction along the Japan Trench in northeast Japan.

Biological surveys reveal unexpectedly high faunal diversity at Nankai Trough methane seeps

Ecosphere
Cold seeps are chemosynthesis‐based ecosystems powered by microbial primary production that support diverse and specialized faunal assemblages in the deep sea. Despite Nankai Trough in Japan being a geologically active margin hosting numerous seeps, much

Thick slab crust with rough basement weakens interplate coupling in the western Nankai Trough

Earth, Planets and Space
The westernmost Nankai Trough, southwest Japan, exhibits a rapid along-strike reduction in plate coupling in the proximity to the subducting Kyushu-Palau ridge. Yet how and to what extent the ridge subduction impacts physical properties at the megathrust

Detailed Shallow Shear Velocity Structure in the Nankai Trough From Ambient Noise Differential Adjoint Tomography: Implications for Earthquake Generation Mechanisms

Geophysical Research Letters
Seismic and aseismic slip has been reported in the Nankai Trough. In this study we apply ambient noise differential adjoint tomography to obtain a high‐resolution S‐wave velocity (Vs) model in the Nankai Trough.

Link between the Nankai underthrust turbidites and shallow slow earthquakes [PDF]

Scientific Reports, 2023
Trench sediments such as pelagic clay or terrigenous turbidites have long been invoked to explain the seismogenic behavior of the megathrust fault (i.e., décollement).

Thermogenic methane and hydrogen generation in subducted sediments of the Nankai Trough

Communications Earth & Environment
Active and widespread CH4 accumulations and emissions in the Nankai Trough subduction zone are attested by numerous mud volcanoes, gas plumes, and gas hydrates containing biogenic and thermogenic CH4.

Muroto Project: Scientifi c Drilling of the Late Pliocene Forearc Basin Deposit on the West Coast of Muroto Peninsula, Shikoku, Japan [PDF]

Scientific Drilling, 2006
The Muroto Peninsula on the Pacifi c margin of southwest Japan (Fig.1) formed as a result of tectonic events associated with oblique subduction along the Nankai Trough (Sugiyama, 1992, 1994). Late Pliocene forearc basin deposits of the Tonohama Group are
