A new chronology for tsunami deposits prior to the 1700 CE Cascadia earthquake from Vancouver Island, Canada [PDF]
Scientific Reports, 2022 Coastal deposits at Tofino, Ucluelet, and Port Alberni in Vancouver Island along the Cascadia subduction zone were re-examined to improve the earthquake history of the southwest coast of Canada.

Seismic evidence for melt-rich lithosphere-asthenosphere boundary beneath young slab at Cascadia [PDF]
Nature CommunicationsThe Lithosphere-Asthenosphere Boundary (LAB) beneath oceanic plates is generally imaged as a sharp seismic velocity reduction, suggesting the presence of partial melts.

Sharp structural variability of the Gorda slab imaged by a fiber array [PDF]
Nature CommunicationsStructural variability at the subduction interface imposes stress and strength heterogeneity that affects the behavior of megathrust earthquakes. Characterizing this variability can be challenging because the slab interface is often deep and seismically ...

Competing Effects of Elastic Heterogeneity and Viscous Flow on Interseismic Coupling at Cascadia
Geophysical Research LettersInterseismic coupling maps are important tools for estimating future earthquake hazard at subduction zones. Often interseismic coupling is estimated from surface velocities using a homogeneous elastic Earth model.

Filling the Gap in Cascadia: The Emergence of Low‐Amplitude Long‐Term Slow Slip
Geochemistry, Geophysics, Geosystems, 2021 Long‐term slow slip events have been observed at several subduction zones around the globe, where they play an integral part in strain release along megathrust faults.
