Mapping Mantle Flows and Slab Anisotropy in the Cascadia Subduction Zone

open access: yesGeophysical Research Letters, 2023
The Cascadia margin is an unusual subduction zone characterized by the downdip movement of young and thin oceanic plates, where mantle flow and intraslab deformation are still unclear. Here we present new anisotropic tomography of the Cascadia subduction

The Hidden History of the South‐Central Cascadia Subduction Zone Recorded on the Juan de Fuca Plate Offshore Southwest Oregon

open access: yesGeochemistry, Geophysics, Geosystems, 2022
New seismic reflection data collected and processed as part of early career scientist training at sea and in classroom projects fill gaps in seismic coverage of the Cascadia subduction zone and provide new insights into anomalous subduction behavior and ...

Toward Models of Impact and Recovery of the US Western Grid from Earthquake Events

open access: yesEnergies, 2022
A Cascadia Subduction Zone (CSZ) earthquake will cause widespread damage to numerous lifelines and infrastructure along the northern US west coast. The goal of the presented research is to provide a bottom up estimate of the impact on and subsequent ...

Isolating non-subduction-driven tectonic processes in Cascadia

open access: yesGeoscience Letters, 2021
Several tectonic processes combine to produce the crustal deformation observed across the Cascadia margin: (1) Cascadia subduction, (2) the northward propagation of the Mendocino Triple Junction (MTJ), (3) the translation of the Sierra Nevada–Great ...

Crustal anisotropy in a subduction zone forearc : Northern Cascadia [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2014
S-wave splitting analyses using high signal-to-noise ratio low frequency earthquake (LFE) templates at 3-component stations across southern Vancouver Island (SVI) and northern Washington indicate the presence of a heterogeneous distribution of crustal anisotropy in the North American plate.

The Cascadia Initiative: A Sea Change In Seismological Studies of Subduction Zones [PDF]

open access: yesOceanography, 2014
Increasing public awareness that the Cascadia subduction zone in the Pacific Northwest is capable of great earthquakes (magnitude 9 and greater) motivates the Cascadia Initiative, an ambitious onshore/offshore seismic and geodetic experiment that takes ...

Probabilistic Tsunami Hazard Analysis for Vancouver Island Coast Using Stochastic Rupture Models for the Cascadia Subduction Earthquakes

open access: yesGeoHazards, 2023
Tsunami hazard analysis is an essential step for designing buildings and infrastructure and for safeguarding people and assets in coastal areas. Coastal communities on Vancouver Island are under threat from the Cascadia megathrust earthquakes and ...
