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.

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.

Structural Controls on Splay Fault Rupture Dynamics During Cascadia Megathrust Earthquakes

AGU Advances
Great subduction earthquakes (Mw ≥ 8.0) can generate devastating tsunamis by rapidly displacing the seafloor and overlying water column. These potentially tsunamigenic seafloor offsets result from coseismic fault slip and deformation beneath or within ...

Spatiotemporal Characteristics of Tectonic Tremors in California

Geophysical Research Letters
California, as a transform plate boundary, provides a distinctive tectonic setting and an ideal natural laboratory for investigating tectonic tremors and the slow deformation associated with plate motion.

Risk-based multi-hazard microzonation for earthquakes and tsunamis

Frontiers in Earth Science
A multi-hazard spatial mapping for shaking and tsunami risks is necessary for coastal communities that face imminent dangers from megathrust subduction earthquakes.

Halos of Enhanced Sediment Alteration Above Buried Seamounts Approaching the Cascadia Subduction Zone

Geochemistry, Geophysics, Geosystems
Sediment thermal history controls the progress of diagenetic reactions that can alter the mechanical behavior of material entering a subduction zone that then: accretes to the margin, hosts the plate boundary interface, or is carried deeper within the ...
