Overview of Ground-Motion Issues for Cascadia Megathrust Events: Simulation of Ground-Motions and Earthquake Site Response

Frontiers in Built Environment, 2017
Ground motions for earthquakes of M7.5 to 9.0 on the Cascadia subduction interface are simulated based on a stochastic finite-fault model and used to estimate average response spectra for reference firm soil conditions.

Incorporating telemetry information into capture‐recapture analyses improves precision and accuracy of abundance estimates given spatiotemporally biased recapture effort

Methods in Ecology and Evolution
Natural populations that are rare, cryptic or inaccessible provide a monumental challenge to monitoring, as adequate data are extremely difficult to collect. Surveys often encompass only a small portion of a population's range due to difficult terrain or

Three-dimensional variations of the slab geometry correlate with earthquake distributions at the Cascadia subduction system

Nature Communications, 2018
Variations in seismicity are observed at subduction zones, but the oceanic sides remain poorly resolved. Here, the author presents tomographic results of the Cascadia subduction system demonstrating that there are significant variations of the oceanic ...

Joint seismic/electrical effective medium modelling of hydrate-bearing marine sediments and an application to the Vancouver Island margin [PDF]

, 2008
Remote determination of the hydrate content of marine sediments remains a challenging problem.In the absence of boreholes, the most commonly used approach involves the measurement of Pwavevelocities from seismic experiments.

Late Quaternary Surface Displacements on Accretionary Wedge Splay Faults in the Cascadia Subduction Zone: Implications for Megathrust Rupture

Seismica
Because splay faults branch at a steep dip angle from the plate-boundary décollement in an accretionary wedge, their coseismic displacement can potentially result in larger tsunamis with distinct characteristics compared to megathrust-only fault ruptures,

Decolonizing cascadia?

, 2014
This essay reflects on attempts to organize a conference that sought to trouble the colonial nature of conference structures, academic knowledges and hierarchies, and the ‘Cascadia’ bioregion of Northwestern North ...

How the Transition Region Along the Cascadia Megathrust Influences Coseismic Behavior: Insights From 2‐D Dynamic Rupture Simulations

Geophysical Research Letters, 2019
There is a strong need to model potential rupture behaviors for the next Cascadia megathrust earthquake. However, there exists significant uncertainty regarding the extent of downdip rupture and rupture speed.

Possible Shallow Tectonic Tremor Signals Near the Deformation Front in Central Cascadia

Seismica
To better constrain the locking state of the shallow Cascadia megathrust, we investigate whether shallow tectonic tremor occurs near the deformation front at ~44.5°N during 2015-2024. We focus on two cabled buried ocean bottom seismometers (OBSs) on the
