Compiled onshore and offshore paleoseismic data along the Cascadia Subduction zone

The USGS Powell Center Cascadia earthquake hazards working group compiled published onshore and offshore paleoseismic data along the Cascadia subduction zone, spanning sites from Vancouver Island to the Mendocino triple junction.

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.

New Insights on the Structure of the Cascadia Subduction Zone from Amphibious Seismic Data

, 2018
A new onshore-offshore seismic dataset from the Cascadia subduction zone was used to characterize mantle lithosphere structure from the ridge to the volcanic arc, and plate interface structure offshore within the seismogenic zone. The Cascadia Initiative

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

, 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.
