Rate-and-state Model Casts New Insight into Episodic Tremor and Slow‐slip Variability in Cascadia [PDF]

, 2019
Advances in geodetic and seismic observations have led to the discovery of Episodic Tremor and Slow‐slip (ETS). ETS in Cascadia subduction zone occurs semiregularly and shows intriguing spatio‐temporal variability reportedly associated with frictional ...

The link between great earthquakes and the subduction of oceanic fracture zones [PDF]

, 2012
Giant subduction earthquakes are known to occur in areas not previously identified as prone to high seismic risk. This highlights the need to better identify subduction zone segments potentially dominated by relatively long (up to 1000 yr and more ...

Seismicity, Repeating Earthquakes, and Tomographic Imaging of the Blanco Transform Fault System, Northeast Pacific

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The Blanco transform fault system (BTFS) represents an evolving transform plate boundary in the Northeast Pacific Ocean. Its seismic behavior was captured with a dense network of 54 ocean‐bottom seismometers (OBS) operated for 1 year. We created a high‐resolution earthquake catalog based on different machine‐learning onset pickers.

The Life and Death of a Tectonic Plate: Imaging the Juan de Fuca Plate with Amphibious Seismic Data [PDF]

, 2019
Understanding of Earth’s evolution has been hindered, in part, by the technical challenges associated with placing seismic instruments on the seafloor. As technology improves, more arrays of ocean bottom seismometers are being deployed around the ocean ...

Heterogeneous coupling of the Sumatran megathrust constrained by geodetic and paleogeodetic measurements [PDF]

, 2008
Geodetic and paleogeodetic measurements of interseismic strain above the Sumatran portion of the Sunda subduction zone reveal a heterogeneous pattern of coupling.

Nine‐Year L‐Band InSAR Time Series of Tectonic and Non‐Tectonic Surface Deformation in Northern California

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract This study evaluates the performance of ALOS‐2 ScanSAR time series for resolving tectonic, volcanic, hydrologic, and geomorphic deformation across Northern California. Beginning in 2021, ALOS‐2 acquired ScanSAR data with a 14‐day repeat interval over the region, providing the closest available analog to the recently launched NISAR mission. The

Extent and Duration of the 2003 Cascadia Slow Earthquake [PDF]

, 2005
Inversion of continuous GPS measurements from the Pacific Northwest show the 2003 Cascadia slow earthquake to be among the largest of ten transients recognized here. Twelve stations bracketing slow slip indicate transient slip propagated bi-directionally

Fault Volume Digital Twin to Reproduce the Full Slip Spectrum, Scaling, and Statistical Laws

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors. We show that incorporating an off‐fault damage zone—characterized by distributed fractures surrounding a main fault—can reproduce many key features observed in ...

Rezente submarine Mineralbildungen : Abbild geochemischer Prozesse an aktiven Fluidaustrittsstellen im Aleuten- und Cascadia-Akkretionskomplex [PDF]

, 1998
Subduction zones with accretionary wedges are potential areas for active fluid transport and expulsion. Upward transport of relatively cold fluids is predominately caused by tectonic compression and usually occurs along geologically predefined conduits ...
