Modeling Surface Mass Load Displacements Along The Cascadia Subduction Zone [PDF]
, 2018 The Earth’s surface is under constant strain from different mass loads. Surface mass loads, such as the oceans, atmosphere, and continental water reservoirs, exert forces on the elastic solid Earth, inducing crustal deformation.

Seismic images of the megathrust rupture during the 25th October 2010 Pagai earthquake, SW Sumatra: Frontal rupture and large tsunami [PDF]
The Mentawai segment of the Sumatra subduction zone is locked and likely to produce a large earthquake in the near future. A part of this locked zone ruptured on 12 September 2007 producing twin earthquakes of Mw = 8.5 and 7.9.

Tectonics, Volume 45, Issue 9, September 2026.Abstract The mechanisms by which new subduction zones form remain highly debated. Here we use Permo‐Triassic strata to evaluate potential mechanisms for initiation of the Talkeetna‐Bonanza Arc of the northern North American Cordillera. New mapping and analysis of Permian and Upper Triassic strata on the Alaska Peninsula suggest a period of uplift ...

Slab pull, slab weakening, and their relation to deep intra-slab seismicity [PDF]
, 2005 Subduction zone seismicity is highly variable. Great earthquakes occur at few subduction zones around the world, with significant variation in size and frequency of deep events. Interactions between overriding and subducting plates and slab pull strength

Poloidal‐ and Toroidal‐Mode Mantle Flows Underneath the Cascadia Subduction Zone
Geophysical Research Letters, 2020 Several hypotheses have been proposed to explain intriguing circular shear wave splitting patterns in the Pacific Northwest, invoking either 2‐D entrained flows or 3‐D return flows. Here, we present some hitherto unidentified, depth‐dependent anisotropic

Cascadia Slow Earthquake Behaviors Modulated by Tectonic and Environmental Forcings
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Slow earthquakes, including episodic tremor and slip (ETS), are highly sensitive to small stress perturbations, yet their links to tectonic and non‐tectonic forcings remain unclear. Previous studies suggest that annual hydrological cycle dominates the tremor seasonal behavior in northern Cascadia.

Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.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.

Potential Bias in Inferred Megathrust Slip Rates Induced by the Neglect of Material Heterogeneity
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.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.

Two-sided asymmetric subduction; implications for tectonomagmatic and metallogenic evolution of the Lut Block, Eastern Iran [PDF]
, 2011 West directed subduction zones show common characteristics, such as low structural elevation, deep trench, steep slab and a conjugate back-arc basin that are opposite to those of the east directed subduction zones.
