Characterizing the Cascadia Subduction Zone for Seismic Hazard Assessments

2014
As part of the BC Hydro PSHA project, a new seismic source model of the Cascadia subduction zone (CSZ) was developed using a logic tree approach. The most significant CSZ seismic source parameters are; the location of the eastern edge of the megathrust rupture zone, rupture zone segmentation, the northern limit of rupture, recurrence models, recurrence

Paleoseismicity of the Southern End of the Cascadia Subduction Zone, Northwestern California

Bulletin of the Seismological Society of America, 2012
The southern end of the Cascadia subduction zone (CSZ) in northwestern California poses a high seismic hazard. This study uses the Quaternary stratigraphy of the bays and estuaries to reconstruct coseismic subsidence caused by strong to great earthquakes.

Seismic reflection imaging of two megathrust shear zones in the northern Cascadia subduction zone

Nature, 2004
At convergent continental margins, the relative motion between the subducting oceanic plate and the overriding continent is usually accommodated by movement along a single, thin interface known as a megathrust. Great thrust earthquakes occur on the shallow part of this interface where the two plates are locked together.

SEISMICITY AND STRESS AT THE SOUTHERN END OF THE CASCADIA SUBDUCTION ZONE

1992
Abstract Three dimensional distribution of well-located seismicity is used to delineate the geometry of lithospheric plates comprising the Mendocino triple junction in northern California. After an understanding of the geometry of the plates is established, first motions of the best located earthquakes are analyzed to identify stress orientations ...

The Cascadia Offshore Subduction Zone Observatory Infrastructure Project

The Cascadia Offshore Subduction Zone Observatory (COSZO) is an NSF-funded Mid-scale Research Infrastructure-1 Project that will add seismic and geodetic instrumentation in summer 2026 to the Ocean Observatories Initiative (OOI) Regional Cabled Array (RCA) off Newport, Oregon. In Cascadia, geophysical observations indicate that the megathrust is mostly

Teleseismic imaging of the southeastern Canadian Shield and Cascadia subduction zone

2009
This thesis is divided into two parts that illustrate different approaches to multichannel analysis of broadband, teleseismic array data. In Part I, a range of established techniques is applied to data from a teleseismic experiment conducted across the southeastern Canadian Shield. Multi-event SKS-splitting results yield an average delay time of 0.57±0.
