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.

Low Hazard–High Risk: A Case Study of the Active Mangatangi Fault

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Activity on low deformation rate faults are challenging to quantify and comparatively understudied. One such fault, the Mangatangi Fault, strikes NE‐SW along the southeastern flanks of the Hunua Ranges c. 52 km south of New Zealand's most populous city, Auckland.

Holocene Slip Behavior and Shallow Structure of the Milun Fault at the Collision–Subduction Transition, Eastern Taiwan

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The Milun Fault forms the northernmost onshore segment of the Longitudinal Valley fault system, a plate‐boundary suture between the Eurasian and Philippine Sea plates in eastern Taiwan, and poses a significant seismic hazard to Hualien City. Despite destructive earthquakes in 1951 and 2018, the shallow structure, long‐term slip behavior, and ...

Fluid‐Driven Cohesive Strengthening: Critical Role of Reaction Kinetics as the Determinant for Frictional Stability

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Following an earthquake, faults lock and regain strength via a combination of healing mechanisms that include pressure solution, contact growth, and cementation. Fault healing dictates strength recovery during the seismic cycle and is therefore a key factor controlling earthquake recurrence intervals, stress drop, and other source properties ...

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).

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.

Breaking up the hanging wall of a rift-border fault: The 2009 Karonga earthquakes, Malawi

The southern East African Rift has an unusually large seismogenic thickness (35–40 km), which is responsible for wide tilted basins and extremely long faults with the potential for M7-8 normal-faulting earthquakes.

Focussing on Proto-Seismogenic Zone of erosional Convergent Margin

, 2004
Great earthquakes in subduction zones occur after stable slip in the proto-seismogenic zone transitions to the unstable slip that characterizes seismogenic zones. Subducted material input to seismogenic zones affects this transition.

Grain Size and Fluid Effects on the Frictional Behavior of Simulated Carbonate Fault Gouge

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Carbonate rocks exhibit a span of clast and grain size in fault zones. However, the effect of grain size distribution on the frictional behavior of carbonate faults and its implications for natural and induced seismicity remain poorly understood.
