Mapping Mantle Flows and Slab Anisotropy in the Cascadia Subduction Zone

Geophysical 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

Geochemistry, 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 ...

Cascadia low frequency earthquakes at the base of an overpressured subduction shear zone

Nature Communications, 2020
Regions of the subducting oceanic crust are often considered to be overpressured, owing to fluid trapped beneath an impermeable seal along the overlying inter-plate boundary.

Applying Automatic Mapping Processing By GMT to Bathymetric and Geophysical Data: Cascadia Subduction Zone, Pacific Ocean [PDF]

Journal of Environmental Geography, 2020
The Cascadia Trench is stretching along the convergent plate boundaries of Pacific Plate, North America Plate and Juan De Fuca Plate. It is an important geomorphological structural feature in the north-east Pacific Ocean.

Seismological structure of the Carpathian-Pannonian region of central Europe [PDF]

, 2010
The extensional Pannonian Basin is set within the convergent arc of the Alpine-Carpathian mountain system in central Europe. Various models have been proposed as mechanisms to drive extension within this collisional setting.

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

Energies, 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

Geoscience 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 ...

Cascadia Subduction Zone Residents’ Tsunami Evacuation Expectations

Geosciences, 2022
The U.S. Pacific Northwest coast must be prepared to evacuate immediately after a Cascadia Subduction Zone earthquake. This requires coastal residents to understand the tsunami threat, have accurate expectations about warning sources, engage in preimpact

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

Oceanography, 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

GeoHazards, 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 ...
