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

AGU Advances
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).

Validation framework for semi-stochastic simulations in Cascadia earthquake early warning

Seismica
We generate a synthetic earthquake dataset for the Cascadia region and present a framework for validating simulations for use in testing earthquake early warning (EEW) performance.

Using Subducting Plate Motion to Constrain Cascadia Slab Geometry and Interface Strength

Geochemistry, Geophysics, Geosystems
Subduction zones are home to multiple geohazards driven by the evolution of the regional tectonics, including earthquakes, volcanic eruptions and landslides.

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

Earth, 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

Geochemistry, 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.

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

Geophysical 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

Geodesy 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

Earth 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.
