Evolution of Pore Fluid Pressure in an Accretionary Outer Wedge Over Megathrust Earthquake Cycles: The Northern Cascadia Example

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The evolution of pore fluid pressure ( Pf$P_{\mathrm{f}}$) in the most seaward portion of a subduction accretionary prism plays an essential role in the cycle of tsunamigenic earthquakes. Based on recent geophysical observations, here we propose a testable conceptual model for this evolution for northern Cascadia offshore of Washington.

Metamorphic Dehydration, Fluid Pressure, and the Frictional‐Viscous Transition Along Subduction Megathrusts: Case Study in Cascadia and Implications for Slow Earthquakes

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Relative plate motion in subduction zones transitions from frictional slip to viscous flow with increasing depth and temperature. The frictional‐viscous transition can control the depth extent of megathrust earthquakes and episodic tremor and slip (ETS).

Fluid-Sediment Interactions in the Nankai Subduction Zone (NanTroSEIZE): Pore Fluid and Mineralogical Records [PDF]

, 2013
The Nankai Trough Seismogenic Zone Experiment (IODP), SW Japan, aimed at unraveling hydrologic processes at subduction megathrusts and in situ rock and fluid properties to understand the fault zone behavior during earthquake nucleation and rupture ...

Friction and mineral assemblage measurements from IODP subduction zone samples

, 2020
We combine here the results of laboratory friction experiments and quantification of mineral assemblage for scientific drilling samples recovered from three particularly well-studied subduction zones: the Nankai Trough (SW Japan), Japan Trench (NE Japan),

Prevalence of mud diapirs in the Hyuga-nada subduction zone, southwest Japan, and its implications on hydrogeological processes

Progress in Earth and Planetary Science
Mud volcanoes, common seafloor features in subduction zone forearcs, provide crucial insights into deep hydrogeological systems associated with plate subduction.

Geodetic Evidence of Time‐Dependent Viscoelastic Interseismic Deformation Driven by Megathrust Locking in the Southwest Japan Subduction Zone

Geophysical Research Letters, 2020
The time‐variable features of interseismic deformation in subduction zones are poorly understood and commonly ignored. Here, by incorporating century‐long leveling data and contemporary global navigation satellite systems (GNSS) velocities, we ...

Detection of slow slip event lasting several months in the shallow region of the Suruga Trough, the eastern end of the Nankai Trough, Japan

Progress in Earth and Planetary Science
Numerous deep short-term slow slip events (S-SSEs) and long-term slow slip events (L-SSEs) have been detected in the Nankai Trough subduction zone in southwestern Japan based on Global Navigation Satellite System (GNSS) data.

The metamorphic evolution of an ancient accretionary prism in the southern zone of the Damara Belt in Namibia [PDF]

, 2013
The Southern Zone of the Damara Belt in central Namibia has an apparent stratigraphic thickness that exceeds 100 km and is comprised of highly strained, metamorphosed clastic sedimentary rocks that are intercalated with slices of metamorphosed basalt and

Slip parameters on major thrusts at a convergent plate boundary: regional heterogeneity of potential slip distance at the shallow portion of the subducting plate

Earth, Planets and Space, 2018
Understanding variations of slip distance along major thrust systems at convergent margins is an important issue for evaluation of near-trench slip and the potential generation of large tsunamis.

Integration of borehole geophysical data and core petrophysical properties to model hydrogeological properties of the Nankai subduction zone

, 2023
Les zones de subduction sont le site d’une intense activité sismique et de grandedéformation tectonique. Le pied du prisme d’accrétion ont été longtemps considéréescomme des zones asismiques où l’énergie des séismes de dissipait.
