Shallow very-low-frequency earthquakes accompany slow slip events in the Nankai subduction zone [PDF]
Nature Communications, 2018 Slow earthquakes are now increasingly recognised to occur at plate boundaries globally. Here, the authors examine seafloor observational data from the Nankai trough and find that very-low-frequency events and slow-slip events frequently occur together ...

Ambient seafloor noise excited by earthquakes in the Nankai subduction zone. [PDF]
Nat Commun, 2015 AbstractExcitations of seismic background noises are mostly related to fluid disturbances in the atmosphere, ocean and the solid Earth. Earthquakes have not been considered as a stationary excitation source because they occur intermittently. Here we report that acoustic-coupled Rayleigh waves (at 0.7–2.0 Hz) travelling in the ocean and marine sediments,

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).

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

Weakening behavior of the shallow megasplay fault in the Nankai subduction zone
Earth, Planets and Space, 2022 The Nankai Trough megasplay fault hosts diverse modes of fault slip, ranging from slow slip events to megathrust earthquakes, and is responsible for related phenomena such as tsunamis and submarine landslides.

Sedimentary inputs to the Nankai subduction zone: The importance of dispersed ash [PDF]
Geosphere, 2018 We examine the importance of dispersed volcanic ash as a critical component of the aluminosilicate sediment entering the Nankai Trough, located south of Japan’s island of Honshu, via the subducting Philippine Sea plate.

Deformation Process and Mechanism of the Frontal Megathrust at the Nankai Subduction Zone
Geochemistry, Geophysics, Geosystems, 2022 The frontal megathrust of the Nankai Trough subduction zone is recognized as a seismogenic fault based on a record of frictional heating, but the underlying micromechanical processes that act on the fault surface are poorly known. Here we present a layer

Role of plate convergence rate in shaping earthquake recurrence in subduction zones [PDF]
Scientific ReportsUnderstanding the complex interplay of subduction zone processes is key to unravelling the timing and distribution of great earthquake cycles within the framework of the plate tectonics paradigm.

Subducted carbon weakens the forearc mantle wedge in a warm subduction zone [PDF]
Nature CommunicationsSubducting oceanic plates carry large amounts of carbon into the Earth’s interior. The subducted carbon is mobilized by fluid and encounters ultramafic rocks in the mantle wedge, resulting in changes to the mineral assemblage and mechanical properties of
