THERMOGENIC PETROLEUM POTENTIAL OF THE NANKAI SUBDUCTION ZONE, OFFSHORE SW JAPAN [PDF]
In the Kumano forearc basin, offshore SW Japan, the potential occurrence of hydrocarbons has been inferred from both geophysical surveys which point to the presence of natural gas hydrates, and geochemical analyses of gas samples recovered from boreholes and submarine mud volcanoes.

A numerical study of the dynamics of subduction [PDF]
The mechanics and dynamics of subduction have been studied using 2-D finite element analysis. Two finite element formulations have been employed; one formulation for Newtonian viscous flow and one formulation for linear elasticity and viscoelasticity ...

We investigated ocean bottom pressure (OBP) observation data at six plate subduction zones around the Pacific Ocean. The six regions included the Hikurangi Trough, the Nankai Trough, the Japan Trench, the Aleutian Trench, the Cascadia Subduction Zone ...

Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes
Abstract Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress conditions deep within fault zones.

Modeling seismically induced deformation and fluid flow in the Nankai subduction zone [PDF]
Fluid pressure changes induced by seismic strains in the Nankai subduction zone were investigated through numerical modeling. Seismic strains resulting from dislocations along fault surfaces were coupled to pore pressure generation, and subsequent transient fluid flow was simulated.

Competing Effects of Elastic Heterogeneity and Viscous Flow on Interseismic Coupling at Cascadia
Abstract Interseismic coupling maps are important tools for estimating future earthquake hazard at subduction zones. Often interseismic coupling is estimated from surface velocities using a homogeneous elastic Earth model. However, inversions that incorporate viscoelastic mantle flow or elastic heterogeneity show that each can change the spatial ...

Potential Bias in Inferred Megathrust Slip Rates Induced by the Neglect of Material Heterogeneity
Abstract Accurate knowledge of the pattern of interseismic coupling on megathrusts is critical to preparing for future earthquakes and tsunamis. However, published models for a given fault zone commonly differ widely, making hazard assessment difficult.

Modelling temporal changes in the gravity field in the Nankai Trough Subduction Zone, Japan [PDF]
The Nankai trough subduction zone off southwest Japan is prone to large earthquakes, causing tsunamis and great damages to the nearby islands. Linking the sources of these earthquakes to asperities along the plate interface is of great importance in ...
