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.

Microscale cavitation as a mechanism for nucleating earthquakes at the base of the seismogenic zone [PDF]
Nature Communications, 2017 AbstractMajor earthquakes frequently nucleate near the base of the seismogenic zone, close to the brittle-ductile transition. Fault zone rupture at greater depths is inhibited by ductile flow of rock. However, the microphysical mechanisms responsible for the transition from ductile flow to seismogenic brittle/frictional behaviour at shallower depths ...

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.

Seismogenic zonation and seismic hazard estimates in a Southern Italy area (Northern Apulia) characterised by moderate seismicity rates [PDF]
Natural Hazards and Earth System Sciences, 2009 The northernmost part of Apulia, in Southern Italy, is an emerged portion of the Adriatic plate, which in past centuries was hit by at least three disastrous earthquakes and at present is occasionally affected by seismic events of moderate energy. In the

Embrittlement Within Viscous Shear Zones Across the Base of the Subduction Thrust Seismogenic Zone
Geochemistry, Geophysics, Geosystems, 2022 Geophysical observations indicate that patches of localized fracturing occur within otherwise viscous regions of subduction plate boundaries. These observations place uncertainty on the possible down‐dip extent of the seismogenic zone, and as a result ...

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 ...

Generating a seismogenic source zone model for the Pyrenees: A GIS-assisted triclustering approach
, 2021 Seismogenic source zone models, including the delineation and the characterization, still have a role to play in seismic hazard calculations, particularly in regions with moderate or low to moderate seismicity. Seismic source zones establish areas with

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 ...

Large Trench-Parallel Gravity Variations Predict Seismogenic Behavior in Subduction Zones [PDF]
, 2003 We demonstrate that great earthquakes occur predominantly in regions with a strongly negative trench-parallel gravity anomaly (TPGA), whereas regions with strongly positive TPGA are relatively aseismic.
