Dynamics of intraoceanic subduction initiation: 1. Oceanic detachment fault inversion and the formation of supra-subduction zone ophiolites [PDF]

open access: yes, 2015
Subduction initiation is a critical link in the plate tectonic cycle. Intraoceanic subduction zones can form along transform faults and fracture zones, but how subduction nucleates parallel to mid-ocean ridges, as in e.g., the Neotethys Ocean during the ...

Analysis of Episodic Tremor and Slip in Cascadia Subduction Zone Using the Displacement and Strain Method [PDF]

open access: yes, 2014
Recent studies have found a periodic phenomenon in some subduction zones called episodic tremor and slip (ETS). This kind of event can be detected by GPS stations and PBO stations.

Revisiting interseismic deformation in Nankai: focusing on slip-deficit accumulation in the ETS zone and comparison with Cascadia

open access: yesEarth, Planets and Space
Various stress-releasing phenomena, such as episodic tremor and slip (ETS) and low-frequency earthquakes, occur at the downdip seismogenic zone in southwest Japan.

Anomalous Sediment Consolidation and Alteration From Buried Incoming Plate Seamounts Along the Cascadia Margin

open access: yesGeochemistry, Geophysics, Geosystems
Oceanic plate seamounts are believed to play an important role in megathrust rupture at subduction zones, although consistent relationships between subducting seamounts and plate interface seismicity patterns are not found.

Subduction plate age as a control on elastic upper-plate thickness in Cascadia: Insights from interseismic GNSS observations and implications

open access: yesEarth and Planetary Physics
Understanding the viscoelastic structure of subduction zones is essential for assessing seismic hazards and understanding subduction-zone dynamics.

Strong Shaking From Past Cascadia Subduction Zone Earthquakes Encoded in Coastal Landforms

open access: yesGeophysical Research Letters
Strong earthquakes along subduction zones are often devastating events, but sparse records along some tectonic margins limit our understanding of seismic hazards.

Slow slip events detection algorithm based on an optimization-based signal decomposition framework: A case study in Cascadia zone

open access: yesGeodesy and Geodynamics
Slow Slip Events (SSEs) are critical for understanding subduction zone tectonics and earthquake prediction; however their detection is challenged by low-magnitude-offsets and data gaps.

Influence of Subduction Interface Geometry on Surface Displacements and Slip Processes in Cascadia

open access: yesEarth and Space Science
The subduction interface geometry is particularly important for estimating interplate coupling and surface geodetic motion, which has significant implications for seismic hazard mapping.

The Distribution of Interseismic Locking on the Cascadia Subduction Zone Using Bayesian Methods

open access: yesSeismica
We use a Bayesian probabilistic framework to invert for the kinematic locking distribution on the Cascadia Subduction Zone, constrained by surface deformation data and a prior assumption of the locking pattern.

A Statistical Analysis of Large Magnitude Earthquakes along the Cascadia Subduction Zone

open access: yes
The Pacific Northwest is home to the Cascadia Subduction Zone, a 1,000 km-long megathrust fault that stretches from Northern California to Southern Canada.
