An exponential build-up in seismic energy suggests a months-long nucleation of slow slip in Cascadia

Nature Communications, 2020
Using machine learning algorithms, the authors here identify slow slip precursors in the Cascadia subduction zone to last for months - which in turn argues for a much better predictability of slow slip rupture.

Differential Vulnerability to Ship Strikes Between Day and Night for Blue, Fin, and Humpback Whales Based on Dive and Movement Data From Medium Duration Archival Tags

Frontiers in Marine Science, 2019
We examine the dive and movement behavior of blue, fin, and humpback whales along the US West Coast in regions with high ship traffic where ship strikes have been identified as a major concern.

Evidence for an active transtensional Beaufort Range fault in the northern Cascadia forearc

Seismica
Geologic records of fault slip in subduction forearcs provide critical data on stress and strain in the upper plate and the seismogenic potential of hazardous faults.

Along-strike changes in ETS behavior near the slab edge of Southern Cascadia

Seismica
Episodic tremor and slip (ETS) is well-documented along the entire length of the Cascadia subduction zone. We explore how the occurrence of ETS varies at the southernmost edge of the subduction zone, where geometric complexity and a slab window likely ...

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 ...

In situ measurements of thermal diffusivity in sediments of the methane-rich zone of Cascadia Margin, NE Pacific Ocean

Elementa: Science of the Anthropocene, 2015
Thermal diffusivity (TD) is a measure of the temperature response of a material to external thermal forcing. In this study, TD values for marine sediments were determined in situ at two locations on the Cascadia Margin using an instrumented sediment ...

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,
